Newton the Alchemist: Science, Enigma, and the Quest for Nature's "Secret Fire" by William Newman

John Maynard Keynes famously cast Isaac Newton not as the first scientist of the age of reason, but the last of the magicians. How should we interpret the million words he wrote, in secret, on alchemy? What should we make of Newton's heretical religious views? William Newman talks us through the best books for a better understanding of the complex man who was one of the greatest physicists of all time.

B efore we talk about the books, it might be helpful if you could briefly put Isaac Newton into the context of the Scientific Revolution of the 17th century.  What was Newton’s contribution?

The first of the books about Isaac Newton you’ve chosen is a biography, Never at Rest by Richard Westfall. Is this the  biography of Newton to read?

It’s a magisterial book. It’s the only treatment of Newton that really tries to give a detailed study of the totality of his science alongside his religion and his work on alchemy, which covered more than 30 years. It is a magnificent product. It’s somewhat dated now, because it appeared in 1980 and Newton scholarship has recently experienced a remarkable change. Some of the other books that I recommended represent attempts to come to terms with sections of Newton’s work in a deeper way than Westfall was able to do in 1980.

Part of the reason for that is because we now have digital sites like the Newton Project in the UK, which has been editing Newton’s theological and religious writings—his prophetic writings more generally—and then the Chymistry of Isaac Newton site that I am the general editor of at Indiana University, that’s been editing the alchemical papers, Newton’s work on chemistry. Westfall didn’t have access to all of that in 1980. So there’s a lot of material that Westfall wasn’t able to take account of, yet all the same, his work is a magnificent synthesis.

You mentioned Newton’s alchemical papers. His work on alchemy is your area of expertise and the subject of your latest book: Newton the Alchemist. Can his alchemical work be seen as foundational for modern science or was it a dead end?

There is currently a widespread ‘master narrative’ of Newton’s alchemy, though one with which I disagree. The major scholars of the subject at that time, especially Westfall, argued that the impact of alchemy on Newton’s more mainstream science lay in his emphasis on invisible forces that could act over a considerable space, such as gravitational attraction. The reason why a lodestone attracted iron at a distance was because of a hidden sympathy between the two, like the occult sympathies governing magical phenomena. Couldn’t this sort of explanation have stimulated Newton to think of gravity in terms of an immaterial attraction? And wasn’t alchemy based on the idea that some materials react with others because of a similar principle of affinity? Thus the idea that Newton’s involvement with alchemy was part of a quest to understand gravitational attraction was born. Contemporary sources ranging from popular outlets such as Wikipedia to serious scholarly monographs echo this theme.

The next book is A Portrait of Isaac Newton by Frank Manuel, which is also a biography. It starts with his childhood in Lincolnshire and has chapters on his time at Cambridge and then in public life in London. What does it add to the story that Westfall doesn’t?

Manuel’s book was published in 1968, so it’s considerably earlier than Westfall’s. Manuel was a brilliant historian and perhaps an even more brilliant writer. I personally think that, of all the books written on Newton, his is stylistically the most engaging. It’s just a terrific read.

The book attempts to provide a kind of Freudian psychoanalytic study of Newton’s character. He tries to explain Newton’s psychology in terms of his childhood lack of a father. One thing that’s interesting about Manuel—and for that matter Westfall and almost everybody else who has come later—is that all these folks were influenced to some degree, perhaps without even realizing it, by John Maynard Keynes .

There was a famous Sotheby’s auction of Newton manuscripts by his heirs in 1936 and Keynes managed to acquire about half of them. Most of them he subsequently gave to King’s College Cambridge, where they remain, but he wrote an extraordinary article called “ Newton the Man” which was published posthumously in 1947. In it, he argues famously that Newton was not the first scientist of the age of reason, but rather the last of the magicians. He tries to debunk the 18th-century view of Newton as a supreme rationalist and even possibly a deist. [Deists, in the 18th century, were people who believed in a supreme benevolent being who had set the universe in motion, but rejected the notion of an interventionist Christian God]

This focus on Newton’s non-scientific side leads us neatly to the next of the books you’ve selected, Newton and the Origins of Civilization by Buchwald and Feingold. This is the latest word on Newton’s biblical-chronological studies.

Jed Buchwald and Mordechai Feingold point out that in the 17th century there was a widespread view among alchemists that the totality of ancient mythology was just encoded alchemy. There are many examples one could give, but I’ll stick with one that comes up in Newton’s “Index Chemicus”, a very long concordance of the alchemical writings that he read. He talks about Osiris, the Egyptian god, as being a sort of salt. He’s relying there on a 17th-century alchemist named Michael Maier, who interpreted Egyptian mythology as encoded alchemy. Maier argued that these stories about the Egyptian gods and goddesses and so forth were actually recipes that were dressed up as though the Egyptians were talking about actual divinities. That was the view of Maier and Newton interprets Maier in his own work on alchemy.

But in other writings on chronology Newton interprets Osiris literally as a god, though in a certain, restricted sense. Newton in his chronological writings worked with Euhemerus’s interpretation of mythology, in which the gods and goddesses of the ancients were originally human beings who were then treated as heroes and catasterised, so to speak, into the heavens as divinities. In other words, his chronological theory based on Egyptian mythology runs directly at odds with the alchemical theory of ancient mythology that he’s taking from Michael Maier. These are very distinct ways of looking at mythology. They are in fact contradictory and mutually exclusive.

I would argue that Newton did not himself believe that the ancients were encoding alchemy in their mythology. Instead, I suspect he thought people like Michael Maier were using mythology as a way of writing alchemical riddles that then had to be decoded if one was going to carry their alchemy into practice.

Part of the book is about the attacks on Newton in England and France and the demise of the science of chronology. Could you tell us a bit about that?

Newton was trying to build his chronology of the ancient world through studying the Bible and using what he knew about mythology. He really thought that you could extract actual dates out of biblical and mythological literature, with the help of astronomy and other scientific tools that he had at his disposal. For example, he tries to date Jason and the Argonauts’ adventures according to what he knew about the precession of the equinoxes. There’s a precession of one degree every 72 years, so he was able to work backwards from what he knew about the position of the equinoctial colures in the 1680s and 1690s and later.

So he’s incorporating astronomical material as a way of pinpointing the dates that he gets from ancient literature. That fell out of style after Newton’s death and by the 19th century it was considered rather ridiculous.

Another key feature of the book is the fact that Feingold and Buchwald have a very different view of Newton’s anti-trinitarianism than the one you get in other writers like Westfall.

So Newton didn’t believe in the Trinity, which was a highly controversial and dangerous position at at that time. In what way do Feingold and Buchwald offer a different view?

Again we need to go back to Keynes. Keynes thought that Newton was a heretic, that he is an anti-trinitarian from the early 1670s, if not earlier. That position has been picked up by other people, for example Westfall. The evidence for it is primarily the fact that Newton refused to take holy orders in 1675. Entering holy orders was a condition of his fellowship at Trinity College. He managed to get a special dispensation and, according to Westfall, Keynes, and various others, the reason why he refused to take holy orders was because he was effectively a crypto-heretic and would not agree to swear that the Trinity—in which the Father, Son, and Holy Spirit are of the same ‘substance’—was a legitimate way of interpreting Christianity.

How does that fit with the next book, Rob Iliffe’s Priest of Nature, because he talks at some length about Newton’s heterodox anti-trinitarianism?

Iliffe takes a noncommittal position in Priest of Nature . There’s no question, of course, that Newton was a heretic. The problem is when did he commit to that idea? Most of his papers on his theological views date from, at the earliest, the 1680s. So there really isn’t much evidence from the 1670s. Iliffe spends a lot of time in his book arguing that Newton came out of a Puritan background and that he was intensely religious from day one. He argues that Newton was heavily influenced by an apothecary named Clark with whom he lived in Grantham when he was a student there at the King’s School, and that the origins of his later heretical views are an outgrowth of this early and intense religiosity.

Newton then entered Trinity College, Cambridge in 1661. Among his papers is a list of his sins that he wrote out in 1662, some of which seem quite trivial, like stealing cherry cobs from a friend in Grantham. He also repents of having wanted to burn down the house of his mother and his stepfather, a guy named Barnabas Smith. To Iliffe these admissions provide evidence of a highly Puritanical young Newton, whereas Feingold and Buchwald regard them as aberrations and point to the relative absence of religious themes in Newton’s surviving student notebooks.

In terms of sins, threatening to burn down his stepfather’s house sounds like quite a serious one.

What happened was that Newton’s father died directly before  he was born in 1642. His mother remarried the rector of a nearby town named Barnabas Smith, but Barnabas Smith was not interested in having the infant Newton in his house. So, although the house was only a couple of miles away, Newton was raised by his grandmother rather than his mother. She lived with Barnabas Smith for seven years and then he died too. Newton was eleven when Barnabas Smith died and his mother came back to live with him.

This is the basis for Manuel’s psychoanalysis. He claims that Newton was essentially angry throughout his entire life because his mother had been snatched away from him by Barnabas Smith.

Can you tell us about his broader heresy: he wasn’t just anti-trinitarian, was he? He thought the church fathers were fraudulent as well. And he was a strong believer that religious pluralism was a good thing. Is that a fair characterization?

Yes, but it’s more complicated. On the one hand, Newton wanted to claim that in order to be a good Christian all you had to do was profess that Jesus was the Son of God, the Father, and that love was the guiding principle, so basic tenets of Christianity. On the other hand, he was vehemently anti-Catholic and this comes out very clearly in his manuscripts. He claims the Nicene Creed, where the Trinity becomes an official part of Christianity, was a “great Apostasy,” and that behind it was a diabolical influence that converted Christianity essentially into a kind of paganism.

So he was vehemently opposed to the Trinity and to the early upholders of the Trinity like the Church father, Athanasius. And he writes that monks are perverts and goes on like this time and time again throughout his manuscripts. So on the one hand he’s very open to a simple view of Christianity, on the other he thinks Catholicism is evil.

And is his objection to the Trinity that it has no biblical warrant?

The final book you’ve chosen is by Niccolo Guicciardini and it’s called Isaac Newton and Natural Philosophy . It’s a much more recent publication. What does this book add to the picture?

Guicciardini’s is the first synthetic book that really tries to incorporate what you could call the new Newton scholarship. He has read and analysed Newton and the Origin of Civilization , Buchwald and  Feingold’s work. He’s also quite familiar with Iliffe’s work. He knows some of my work on Newton’s alchemy and he really does try to come to a new synthesis. You get a picture of Newton not so much as a kind of psychopath—that you get in Manuel and to some degree Westfall—but rather Newton as a kind of ‘Caltech geek,’ as Mordechai Feingold has put it. He is somebody who’s on the spectrum, but is not outright crazy.

To what extent did Newton’s achievements in natural philosophy lead him or others to dismiss the views he held on biblical literalism and chronology?

I would say that Newton’s influence in natural philosophy ultimately led away from the very things that he was trying to push not just in chronology, but also in religion more generally. For example, the second edition of the Principia , his major work on gravitation and so forth, includes something called the “General Scholium”, which is an attempt to argue for the necessity of God as the being that orders the universe. That’s absent from the first edition of the Principia . Newton was clearly worried that his natural philosophical work was going to lead, if not directly to atheism, then to a kind of disregard for religion. So you see him inserting these attempts to link his natural philosophical ideas to the necessity of religion in various different works of his.

Another example would be in the 1717 edition of the Optics . The Optics contains so-called “queries” that are hypothetical and Newton frames them in the form of questions. The last query makes a strong argument against Descartes’s idea that there is a fixed amount of motion in the universe, that motion is just getting transferred from one microscopic corpuscle to another, and so that motion could go on forever. Newton argues directly against that and for the necessity of what he calls “active principles”, which ultimately clearly go back to God. He thinks there’s an active principle behind gravity, that there’s an active principle behind magnetism and that there’s an active principle behind electricity. Clearly he’s trying to link these natural phenomena back to the necessity for the existence of a divinity.

So he was very worried about this and he was right to be so. Ultimately the Newtonian world picture did make it unnecessary to invoke direct divine causation. This is one of the reasons why Newton doesn’t like Descartes, because he felt that Cartesianism would lead to atheism. But ultimately the same thing could be said of his own natural philosophy.

Did he address that directly?

In the “General Scholium” he argues very clearly not only that there is a God, but that God is the Lord, the ruler of all. He has a very Old Testament view of God, which is obviously related to his unitarianism. He thinks that Jesus was the son of God, but Jesus nonetheless is not part of God in the way that the trinitarians believe.

There’s another issue that is worth mentioning and that is the issue of compartmentalization of Newton’s thought, a topic that Iliffe discusses. Newton was essentially brilliant at everything that he undertook seriously. Obviously, he was particularly successful in the realm of natural philosophy, what we would call physics, but the same can be said of his religious writings. They really are highly original and extremely ingenious, even if you don’t believe them. The same can be said of his alchemical writing. He was making compounds that people may or may not have discovered even today.

This leads to a different question, which is, how did all of these different pursuits integrate or did they? I hinted at this earlier with the issue of chronology and alchemy and the interpretation of mythology, and how it seems that Isaac Newton was keeping the alchemical and the historical interpretations of mythology quite distinct.

The issue of compartmentalization has really come to the fore as a result of more and more rigorous scholarship on these different aspects of Newton’s thought. These works that I’ve recommended to you, in particular Buchwald and Feingold and Iliffe, are carrying out research on particular aspects of Isaac Newton’s thought in more and more detail. And so the question of how to deal with all of these different sides of Newton has become really very problematic. Guicciardini deals with this I think rather successfully, but nonetheless questions remain as to how you approach this extreme compartmentalization. Is there a relationship between Newton’s ideas on physics and his ideas on alchemy, for example, and if so, what is its precise character?

Even if Newton hadn’t found the unifying factor amongst all these things, Newton must have thought there must be some coherence between them.

I’m not sure that’s right. I don’t know. The problem is you have this guy who is clearly an out-of-control genius. Isaac Newton gets interested in something and he pursues it to the nth degree. He almost can’t control himself. It’s like he can’t turn his brain off. So he just happens to be incredibly good at almost anything he does. Let me give you a parallel example from personal experience. I had a colleague years ago, at Indiana University, who was a brilliant philosopher of science. He was also an Epicurean cook and he also was so good at playing the French horn that he was able to play it in an orchestra in a major city. Did he think all those things were connected? I’m not so sure.

If someone believes in a God who’s the author of the universe, then it implies there must be a coherence between all areas of knowledge. I suppose that’s why I thought he must he must have felt there was some sort of coherence between all these things—some underlying laws.

I think that’s true, but at such an abstract and general level that it might not even touch Isaac Newton’s actual work. For instance, Newton’s view of Christianity ultimately boiled down to very general precepts such as ‘Love thy neighbour,’ ‘Profess the reality of Jesus Christ as the Son of the Father,’ and that kind of thing. So all of the incredibly detailed work that he did in interpreting prophecy, for example, or in writing against the Trinity, may not really have interacted with those very general precepts in any significant way. Isaac Newton was a virtuoso at practically everything he undertook, and virtuosity in multiple areas of endeavour need not imply their interconnectedness.

The problem of assuming an underlying unity to Isaac Newton’s thought also emerges from an examination of his alchemy. The issue with alchemy is problematic because alchemical writings are often filled with references to God. And the reason for that I think is because alchemists themselves were constantly under threat of being accused of counterfeiting and so forth. So they tried to build up the picture of themselves as extremely religious people. I really think that’s the case. When [the Newton historian] Betty Jo Dobbs interpreted that material in his manuscripts she came to the conclusion that, ‘Yes, of course, this is really all about Isaac Newton’s religion.’ Yet there’s actually very little evidence to support Dobbs’s view, because if you look at the work Isaac Newton wrote on theology, there are practically no references to alchemy. In reality it appears that he kept these topics in fairly watertight compartments. So as historians we have to be very, very careful not to make assumptions. Typically we want to say all of these things are related, but maybe not. They may simply reflect virtuoso performances in a variety of unrelated or only loosely related areas rather than manifestations of a single underlying quest for unity.

Although Isaac Newton is well known for his discoveries in optics (white light composition) and mathematics ( calculus ), it is his formulation of the three laws of motion —the basic principles of modern physics—for which he is most famous. His formulation of the laws of motion resulted in the law of universal gravitation .

After interrupted attendance at the grammar school in Grantham, Lincolnshire , England , Isaac Newton finally settled down to prepare for university, going on to Trinity College, Cambridge , in 1661, somewhat older than his classmates. There he immersed himself in Aristotle ’s work and discovered the works of René Descartes before graduating in 1665 with a bachelor’s degree.

Isaac Newton was born to a widowed mother (his father died three months prior) and was not expected to survive, being tiny and weak. Shortly thereafter Newton was sent by his stepfather, the well-to-do minister Barnabas Smith, to live with his grandmother and was separated from his mother until Smith’s death in 1653.

What did Isaac Newton write?

Isaac Newton is widely known for his published work Philosophiae Naturalis Principia Mathematica (1687), commonly known as the  Principia . His laws of motion first appeared in this work. It is one of the most important single works in the history of modern science .

Isaac Newton (born December 25, 1642 [January 4, 1643, New Style], Woolsthorpe, Lincolnshire , England—died March 20 [March 31], 1727, London) was an English physicist and mathematician who was the culminating figure of the Scientific Revolution of the 17th century. In optics , his discovery of the composition of white light integrated the phenomena of colours into the science of light and laid the foundation for modern physical optics. In mechanics , his three laws of motion , the basic principles of modern physics , resulted in the formulation of the law of universal gravitation . In mathematics , he was the original discoverer of the infinitesimal calculus . Newton’s Philosophiae Naturalis Principia Mathematica ( Mathematical Principles of Natural Philosophy , 1687) was one of the most important single works in the history of modern science.

Born in the hamlet of Woolsthorpe, Newton was the only son of a local yeoman , also Isaac Newton, who had died three months before, and of Hannah Ayscough. That same year, at Arcetri near Florence, Galileo Galilei had died; Newton would eventually pick up his idea of a mathematical science of motion and bring his work to full fruition . A tiny and weak baby, Newton was not expected to survive his first day of life, much less 84 years. Deprived of a father before birth, he soon lost his mother as well, for within two years she married a second time; her husband, the well-to-do minister Barnabas Smith, left young Isaac with his grandmother and moved to a neighbouring village to raise a son and two daughters. For nine years, until the death of Barnabas Smith in 1653, Isaac was effectively separated from his mother, and his pronounced psychotic tendencies have been ascribed to this traumatic event. That he hated his stepfather we may be sure. When he examined the state of his soul in 1662 and compiled a catalog of sins in shorthand, he remembered “Threatning my father and mother Smith to burne them and the house over them.” The acute sense of insecurity that rendered him obsessively anxious when his work was published and irrationally violent when he defended it accompanied Newton throughout his life and can plausibly be traced to his early years.

After his mother was widowed a second time, she determined that her first-born son should manage her now considerable property. It quickly became apparent, however, that this would be a disaster, both for the estate and for Newton. He could not bring himself to concentrate on rural affairs—set to watch the cattle, he would curl up under a tree with a book. Fortunately, the mistake was recognized, and Newton was sent back to the grammar school in Grantham , where he had already studied, to prepare for the university. As with many of the leading scientists of the age, he left behind in Grantham anecdotes about his mechanical ability and his skill in building models of machines, such as clocks and windmills . At the school he apparently gained a firm command of Latin but probably received no more than a smattering of arithmetic. By June 1661 he was ready to matriculate at Trinity College , Cambridge , somewhat older than the other undergraduates because of his interrupted education.

When Newton arrived in Cambridge in 1661, the movement now known as the Scientific Revolution was well advanced, and many of the works basic to modern science had appeared. Astronomers from Nicolaus Copernicus to Johannes Kepler had elaborated the heliocentric system of the universe . Galileo had proposed the foundations of a new mechanics built on the principle of inertia . Led by René Descartes , philosophers had begun to formulate a new conception of nature as an intricate, impersonal, and inert machine. Yet as far as the universities of Europe, including Cambridge, were concerned, all this might well have never happened. They continued to be the strongholds of outmoded Aristotelianism , which rested on a geocentric view of the universe and dealt with nature in qualitative rather than quantitative terms.

Like thousands of other undergraduates, Newton began his higher education by immersing himself in Aristotle’s work. Even though the new philosophy was not in the curriculum, it was in the air. Some time during his undergraduate career, Newton discovered the works of the French natural philosopher Descartes and the other mechanical philosophers, who, in contrast to Aristotle, viewed physical reality as composed entirely of particles of matter in motion and who held that all the phenomena of nature result from their mechanical interaction. A new set of notes, which he entitled “ Quaestiones Quaedam Philosophicae ” (“Certain Philosophical Questions”), begun sometime in 1664, usurped the unused pages of a notebook intended for traditional scholastic exercises; under the title he entered the slogan “Amicus Plato amicus Aristoteles magis amica veritas” (“Plato is my friend, Aristotle is my friend, but my best friend is truth”). Newton’s scientific career had begun.

The “Quaestiones” reveal that Newton had discovered the new conception of nature that provided the framework of the Scientific Revolution. He had thoroughly mastered the works of Descartes and had also discovered that the French philosopher Pierre Gassendi had revived atomism , an alternative mechanical system to explain nature. The “Quaestiones” also reveal that Newton already was inclined to find the latter a more attractive philosophy than Cartesian natural philosophy, which rejected the existence of ultimate indivisible particles. The works of the 17th-century chemist Robert Boyle provided the foundation for Newton’s considerable work in chemistry. Significantly, he had read Henry More , the Cambridge Platonist, and was thereby introduced to another intellectual world, the magical Hermetic tradition, which sought to explain natural phenomena in terms of alchemical and magical concepts. The two traditions of natural philosophy, the mechanical and the Hermetic, antithetical though they appear, continued to influence his thought and in their tension supplied the fundamental theme of his scientific career.

Although he did not record it in the “Quaestiones,” Newton had also begun his mathematical studies. He again started with Descartes, from whose La Géometrie he branched out into the other literature of modern analysis with its application of algebraic techniques to problems of geometry . He then reached back for the support of classical geometry. Within little more than a year, he had mastered the literature; and, pursuing his own line of analysis, he began to move into new territory. He discovered the binomial theorem , and he developed the calculus , a more powerful form of analysis that employs infinitesimal considerations in finding the slopes of curves and areas under curves.

By 1669 Newton was ready to write a tract summarizing his progress, De Analysi per Aequationes Numeri Terminorum Infinitas (“On Analysis by Infinite Series”), which circulated in manuscript through a limited circle and made his name known. During the next two years he revised it as De methodis serierum et fluxionum (“ On the Methods of Series and Fluxions ”). The word fluxions , Newton’s private rubric, indicates that the calculus had been born. Despite the fact that only a handful of savants were even aware of Newton’s existence, he had arrived at the point where he had become the leading mathematician in Europe.

When Newton received the bachelor’s degree in April 1665, the most remarkable undergraduate career in the history of university education had passed unrecognized. On his own, without formal guidance, he had sought out the new philosophy and the new mathematics and made them his own, but he had confined the progress of his studies to his notebooks. Then, in 1665, the plague closed the university, and for most of the following two years he was forced to stay at his home, contemplating at leisure what he had learned. During the plague years Newton laid the foundations of the calculus and extended an earlier insight into an essay, “Of Colours,” which contains most of the ideas elaborated in his Opticks . It was during this time that he examined the elements of circular motion and, applying his analysis to the Moon and the planets , derived the inverse square relation that the radially directed force acting on a planet decreases with the square of its distance from the Sun —which was later crucial to the law of universal gravitation. The world heard nothing of these discoveries.

Isaac Newton

Isaac Newton was an English physicist and mathematician famous for his laws of physics. He was a key figure in the Scientific Revolution of the 17th century.

(1643-1727)

Who Was Isaac Newton?

In 1687, he published his most acclaimed work, Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) , which has been called the single most influential book on physics. In 1705, he was knighted by Queen Anne of England, making him Sir Isaac Newton.

Early Life and Family

Newton was born on January 4, 1643, in Woolsthorpe, Lincolnshire, England. Using the "old" Julian calendar, Newton's birth date is sometimes displayed as December 25, 1642.

Newton was the only son of a prosperous local farmer, also named Isaac, who died three months before he was born. A premature baby born tiny and weak, Newton was not expected to survive.

When he was 3 years old, his mother, Hannah Ayscough Newton, remarried a well-to-do minister, Barnabas Smith, and went to live with him, leaving young Newton with his maternal grandmother.

The experience left an indelible imprint on Newton, later manifesting itself as an acute sense of insecurity. He anxiously obsessed over his published work, defending its merits with irrational behavior.

At age 12, Newton was reunited with his mother after her second husband died. She brought along her three small children from her second marriage.

Isaac Newton's Education

Newton was enrolled at the King's School in Grantham, a town in Lincolnshire, where he lodged with a local apothecary and was introduced to the fascinating world of chemistry.

His mother pulled him out of school at age 12. Her plan was to make him a farmer and have him tend the farm. Newton failed miserably, as he found farming monotonous. Newton was soon sent back to King's School to finish his basic education.

Perhaps sensing the young man's innate intellectual abilities, his uncle, a graduate of the University of Cambridge's Trinity College , persuaded Newton's mother to have him enter the university. Newton enrolled in a program similar to a work-study in 1661, and subsequently waited on tables and took care of wealthier students' rooms.

Scientific Revolution

When Newton arrived at Cambridge, the Scientific Revolution of the 17th century was already in full force. The heliocentric view of the universe—theorized by astronomers Nicolaus Copernicus and Johannes Kepler, and later refined by Galileo —was well known in most European academic circles.

Philosopher René Descartes had begun to formulate a new concept of nature as an intricate, impersonal and inert machine. Yet, like most universities in Europe, Cambridge was steeped in Aristotelian philosophy and a view of nature resting on a geocentric view of the universe, dealing with nature in qualitative rather than quantitative terms.

During his first three years at Cambridge, Newton was taught the standard curriculum but was fascinated with the more advanced science. All his spare time was spent reading from the modern philosophers. The result was a less-than-stellar performance, but one that is understandable, given his dual course of study.

It was during this time that Newton kept a second set of notes, entitled "Quaestiones Quaedam Philosophicae" ("Certain Philosophical Questions"). The "Quaestiones" reveal that Newton had discovered the new concept of nature that provided the framework for the Scientific Revolution. Though Newton graduated without honors or distinctions, his efforts won him the title of scholar and four years of financial support for future education.

In 1665, the bubonic plague that was ravaging Europe had come to Cambridge, forcing the university to close. After a two-year hiatus, Newton returned to Cambridge in 1667 and was elected a minor fellow at Trinity College, as he was still not considered a standout scholar.

In the ensuing years, his fortune improved. Newton received his Master of Arts degree in 1669, before he was 27. During this time, he came across Nicholas Mercator's published book on methods for dealing with infinite series.

Newton quickly wrote a treatise, De Analysi , expounding his own wider-ranging results. He shared this with friend and mentor Isaac Barrow, but didn't include his name as author.

In June 1669, Barrow shared the unaccredited manuscript with British mathematician John Collins. In August 1669, Barrow identified its author to Collins as "Mr. Newton ... very young ... but of an extraordinary genius and proficiency in these things."

Newton's work was brought to the attention of the mathematics community for the first time. Shortly afterward, Barrow resigned his Lucasian professorship at Cambridge, and Newton assumed the chair.

Isaac Newton’s Discoveries

Newton made discoveries in optics, motion and mathematics. Newton theorized that white light was a composite of all colors of the spectrum, and that light was composed of particles.

His momentous book on physics, Principia , contains information on nearly all of the essential concepts of physics except energy, ultimately helping him to explain the laws of motion and the theory of gravity. Along with mathematician Gottfried Wilhelm von Leibniz, Newton is credited for developing essential theories of calculus.

Isaac Newton Inventions

Newton's first major public scientific achievement was designing and constructing a reflecting telescope in 1668. As a professor at Cambridge, Newton was required to deliver an annual course of lectures and chose optics as his initial topic. He used his telescope to study optics and help prove his theory of light and color.

The Royal Society asked for a demonstration of his reflecting telescope in 1671, and the organization's interest encouraged Newton to publish his notes on light, optics and color in 1672. These notes were later published as part of Newton's Opticks: Or, A treatise of the Reflections, Refractions, Inflections and Colours of Light .

The Apple Myth

Between 1665 and 1667, Newton returned home from Trinity College to pursue his private study, as school was closed due to the Great Plague. Legend has it that, at this time, Newton experienced his famous inspiration of gravity with the falling apple. According to this common myth, Newton was sitting under an apple tree when a fruit fell and hit him on the head, inspiring him to suddenly come up with the theory of gravity.

While there is no evidence that the apple actually hit Newton on the head, he did see an apple fall from a tree, leading him to wonder why it fell straight down and not at an angle. Consequently, he began exploring the theories of motion and gravity.

It was during this 18-month hiatus as a student that Newton conceived many of his most important insights—including the method of infinitesimal calculus, the foundations for his theory of light and color, and the laws of planetary motion—that eventually led to the publication of his physics book Principia and his theory of gravity.

Isaac Newton’s Laws of Motion

In 1687, following 18 months of intense and effectively nonstop work, Newton published Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) , most often known as Principia .

Principia is said to be the single most influential book on physics and possibly all of science. Its publication immediately raised Newton to international prominence.

Principia offers an exact quantitative description of bodies in motion, with three basic but important laws of motion:

A stationary body will stay stationary unless an external force is applied to it.

Force is equal to mass times acceleration, and a change in motion (i.e., change in speed) is proportional to the force applied.

For every action, there is an equal and opposite reaction.

Newton and the Theory of Gravity

Newton’s three basic laws of motion outlined in Principia helped him arrive at his theory of gravity. Newton’s law of universal gravitation states that two objects attract each other with a force of gravitational attraction that’s proportional to their masses and inversely proportional to the square of the distance between their centers.

These laws helped explain not only elliptical planetary orbits but nearly every other motion in the universe: how the planets are kept in orbit by the pull of the sun’s gravity; how the moon revolves around Earth and the moons of Jupiter revolve around it; and how comets revolve in elliptical orbits around the sun.

They also allowed him to calculate the mass of each planet, calculate the flattening of the Earth at the poles and the bulge at the equator, and how the gravitational pull of the sun and moon create the Earth’s tides. In Newton's account, gravity kept the universe balanced, made it work, and brought heaven and Earth together in one great equation.

Isaac Newton & Robert Hooke

Not everyone at the Royal Academy was enthusiastic about Newton’s discoveries in optics and 1672 publication of Opticks: Or, A treatise of the Reflections, Refractions, Inflections and Colours of Light . Among the dissenters was Robert Hooke , one of the original members of the Royal Academy and a scientist who was accomplished in a number of areas, including mechanics and optics.

While Newton theorized that light was composed of particles, Hooke believed it was composed of waves. Hooke quickly condemned Newton's paper in condescending terms, and attacked Newton's methodology and conclusions.

Hooke was not the only one to question Newton's work in optics. Renowned Dutch scientist Christiaan Huygens and a number of French Jesuits also raised objections. But because of Hooke's association with the Royal Society and his own work in optics, his criticism stung Newton the worst.

Unable to handle the critique, he went into a rage—a reaction to criticism that was to continue throughout his life. Newton denied Hooke's charge that his theories had any shortcomings and argued the importance of his discoveries to all of science.

In the ensuing months, the exchange between the two men grew more acrimonious, and soon Newton threatened to quit the Royal Society altogether. He remained only when several other members assured him that the Fellows held him in high esteem.

The rivalry between Newton and Hooke would continue for several years thereafter. Then, in 1678, Newton suffered a complete nervous breakdown and the correspondence abruptly ended. The death of his mother the following year caused him to become even more isolated, and for six years he withdrew from intellectual exchange except when others initiated correspondence, which he always kept short.

During his hiatus from public life, Newton returned to his study of gravitation and its effects on the orbits of planets. Ironically, the impetus that put Newton on the right direction in this study came from Robert Hooke.

In a 1679 letter of general correspondence to Royal Society members for contributions, Hooke wrote to Newton and brought up the question of planetary motion, suggesting that a formula involving the inverse squares might explain the attraction between planets and the shape of their orbits.

Subsequent exchanges transpired before Newton quickly broke off the correspondence once again. But Hooke's idea was soon incorporated into Newton's work on planetary motion, and from his notes it appears he had quickly drawn his own conclusions by 1680, though he kept his discoveries to himself.

In early 1684, in a conversation with fellow Royal Society members Christopher Wren and Edmond Halley, Hooke made his case on the proof for planetary motion. Both Wren and Halley thought he was on to something, but pointed out that a mathematical demonstration was needed.

In August 1684, Halley traveled to Cambridge to visit with Newton, who was coming out of his seclusion. Halley idly asked him what shape the orbit of a planet would take if its attraction to the sun followed the inverse square of the distance between them (Hooke's theory).

Newton knew the answer, due to his concentrated work for the past six years, and replied, "An ellipse." Newton claimed to have solved the problem some 18 years prior, during his hiatus from Cambridge and the plague, but he was unable to find his notes. Halley persuaded him to work out the problem mathematically and offered to pay all costs so that the ideas might be published, which it was, in Newton’s Principia .

Upon the publication of the first edition of Principia in 1687, Robert Hooke immediately accused Newton of plagiarism, claiming that he had discovered the theory of inverse squares and that Newton had stolen his work. The charge was unfounded, as most scientists knew, for Hooke had only theorized on the idea and had never brought it to any level of proof.

Newton, however, was furious and strongly defended his discoveries. He withdrew all references to Hooke in his notes and threatened to withdraw from publishing the subsequent edition of Principia altogether.

Halley, who had invested much of himself in Newton's work, tried to make peace between the two men. While Newton begrudgingly agreed to insert a joint acknowledgment of Hooke's work (shared with Wren and Halley) in his discussion of the law of inverse squares, it did nothing to placate Hooke.

As the years went on, Hooke's life began to unravel. His beloved niece and companion died the same year that Principia was published, in 1687. As Newton's reputation and fame grew, Hooke's declined, causing him to become even more bitter and loathsome toward his rival.

To the very end, Hooke took every opportunity he could to offend Newton. Knowing that his rival would soon be elected president of the Royal Society, Hooke refused to retire until the year of his death, in 1703.

Newton and Alchemy

Following the publication of Principia , Newton was ready for a new direction in life. He no longer found contentment in his position at Cambridge and was becoming more involved in other issues.

He helped lead the resistance to King James II's attempts to reinstitute Catholic teaching at Cambridge, and in 1689 he was elected to represent Cambridge in Parliament.

While in London, Newton acquainted himself with a broader group of intellectuals and became acquainted with political philosopher John Locke . Though many of the scientists on the continent continued to teach the mechanical world according to Aristotle , a young generation of British scientists became captivated with Newton's new view of the physical world and recognized him as their leader.

One of these admirers was Nicolas Fatio de Duillier, a Swiss mathematician whom Newton befriended while in London.

However, within a few years, Newton fell into another nervous breakdown in 1693. The cause is open to speculation: his disappointment over not being appointed to a higher position by England's new monarchs, William III and Mary II, or the subsequent loss of his friendship with Duillier; exhaustion from being overworked; or perhaps chronic mercury poisoning after decades of alchemical research.

It's difficult to know the exact cause, but evidence suggests that letters written by Newton to several of his London acquaintances and friends, including Duillier, seemed deranged and paranoiac, and accused them of betrayal and conspiracy.

Oddly enough, Newton recovered quickly, wrote letters of apology to friends, and was back to work within a few months. He emerged with all his intellectual facilities intact, but seemed to have lost interest in scientific problems and now favored pursuing prophecy and scripture and the study of alchemy.

While some might see this as work beneath the man who had revolutionized science, it might be more properly attributed to Newton responding to the issues of the time in turbulent 17th century Britain.

Many intellectuals were grappling with the meaning of many different subjects, not least of which were religion, politics and the very purpose of life. Modern science was still so new that no one knew for sure how it measured up against older philosophies.

Gold Standard

In 1696, Newton was able to attain the governmental position he had long sought: warden of the Mint; after acquiring this new title, he permanently moved to London and lived with his niece, Catherine Barton.

Barton was the mistress of Lord Halifax, a high-ranking government official who was instrumental in having Newton promoted, in 1699, to master of the Mint—a position that he would hold until his death.

Not wanting it to be considered a mere honorary position, Newton approached the job in earnest, reforming the currency and severely punishing counterfeiters. As master of the Mint, Newton moved the British currency, the pound sterling, from the silver to the gold standard.

The Royal Society

In 1703, Newton was elected president of the Royal Society upon Robert Hooke's death. However, Newton never seemed to understand the notion of science as a cooperative venture, and his ambition and fierce defense of his own discoveries continued to lead him from one conflict to another with other scientists.

By most accounts, Newton's tenure at the society was tyrannical and autocratic; he was able to control the lives and careers of younger scientists with absolute power.

In 1705, in a controversy that had been brewing for several years, German mathematician Gottfried Leibniz publicly accused Newton of plagiarizing his research, claiming he had discovered infinitesimal calculus several years before the publication of Principia .

In 1712, the Royal Society appointed a committee to investigate the matter. Of course, since Newton was president of the society, he was able to appoint the committee's members and oversee its investigation. Not surprisingly, the committee concluded Newton's priority over the discovery.

That same year, in another of Newton's more flagrant episodes of tyranny, he published without permission the notes of astronomer John Flamsteed. It seems the astronomer had collected a massive body of data from his years at the Royal Observatory at Greenwich, England.

Newton had requested a large volume of Flamsteed's notes for his revisions to Principia . Annoyed when Flamsteed wouldn't provide him with more information as quickly as he wanted it, Newton used his influence as president of the Royal Society to be named the chairman of the body of "visitors" responsible for the Royal Observatory.

He then tried to force the immediate publication of Flamsteed's catalogue of the stars, as well as all of Flamsteed's notes, edited and unedited. To add insult to injury, Newton arranged for Flamsteed's mortal enemy, Edmund Halley, to prepare the notes for press.

Flamsteed was finally able to get a court order forcing Newton to cease his plans for publication and return the notes—one of the few times that Newton was bested by one of his rivals.

Final Years

Toward the end of this life, Newton lived at Cranbury Park, near Winchester, England, with his niece, Catherine (Barton) Conduitt, and her husband, John Conduitt.

By this time, Newton had become one of the most famous men in Europe. His scientific discoveries were unchallenged. He also had become wealthy, investing his sizable income wisely and bestowing sizable gifts to charity.

Despite his fame, Newton's life was far from perfect: He never married or made many friends, and in his later years, a combination of pride, insecurity and side trips on peculiar scientific inquiries led even some of his few friends to worry about his mental stability.

By the time he reached 80 years of age, Newton was experiencing digestion problems and had to drastically change his diet and mobility.

In March 1727, Newton experienced severe pain in his abdomen and blacked out, never to regain consciousness. He died the next day, on March 31, 1727, at the age of 84.

Newton's fame grew even more after his death, as many of his contemporaries proclaimed him the greatest genius who ever lived. Maybe a slight exaggeration, but his discoveries had a large impact on Western thought, leading to comparisons to the likes of Plato , Aristotle and Galileo.

Although his discoveries were among many made during the Scientific Revolution, Newton's universal principles of gravity found no parallels in science at the time.

Of course, Newton was proven wrong on some of his key assumptions. In the 20th century, Albert Einstein would overturn Newton's concept of the universe, stating that space, distance and motion were not absolute but relative and that the universe was more fantastic than Newton had ever conceived.

Newton might not have been surprised: In his later life, when asked for an assessment of his achievements, he replied, "I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself now and then in finding a smoother pebble or prettier shell than ordinary, while the great ocean of truth lay all undiscovered before me."

Sir Isaac Newton (Jan. 4, 1643–March 31, 1727) was a superstar of physics, math, and astronomy even in his own time. He occupied the chair of Lucasian Professor of Mathematics at the University of Cambridge in England, the same role later filled, centuries later, by Stephen Hawking . Newton conceived of several laws of motion , influential mathematical principals which, to this day, scientists use to explain how the universe works.

Early Years and Influences

Newton was born in 1642 in a manor house in Lincolnshire, England. His father had died two months before his birth. When Newton was 3 his mother remarried and he remained with his grandmother. He was not interested in the family farm, so he was sent to Cambridge University to study.

Newton was born just a short time after the death of  Galileo , one of the greatest scientists of all time. Galileo had proved that the planets revolve around the sun, not the earth as people thought at the time. Newton was very interested in the discoveries of Galileo and others. Newton thought the universe worked like a machine and that a few simple laws governed it. Like Galileo, he realized that mathematics was the way to explain and prove those laws.

Laws of Motion

Newton formulated laws of motion and gravitation. These laws are math formulas that explain how objects move when a force acts on them. Newton published his most famous book, "Principia," in 1687 while he was a mathematics professor at Trinity College in Cambridge. In "Principia," Newton explained three basic laws that govern the way objects move. He also described his theory of gravity, the force that causes things to fall down. Newton then used his laws to show that the planets revolve around the suns in orbits that are oval, not round.

The three laws are often called Newton’s Laws. The first law states that an object that is not being pushed or pulled by some force will stay still or will keep moving in a straight line at a steady speed. For example, if someone is riding a bike and jumps off before the bike is stopped, what happens? The bike continues on until it falls over. The tendency of an object to remain still or keep moving in a straight line at a steady speed is called inertia.

The second law explains how a force acts on an object. An object accelerates in the direction the force is moving it. If someone gets on a bike and pushes the pedals forward, the bike will begin to move. If someone gives the bike a push from behind, the bike will speed up. If the rider pushes back on the pedals, the bike will slow down. If the rider turns the handlebars, the bike will change direction.

The third law states that if an object is pushed or pulled, it will push or pull equally in the opposite direction. If someone lifts a heavy box, they use force to push it up. The box is heavy because it is producing an equal force downward on the lifter’s arms. The weight is transferred through the lifter’s legs to the floor. The floor also presses upward with an equal force. If the floor pushed back with less force, the person lifting the box would fall through the floor. If it pushed back with more force, the lifter would fly up in the air.

Importance of Gravity

When most people think of Newton, they think of him sitting under an apple tree observing an apple fall to the ground. When he saw the apple fall, Newton began to think about a specific kind of motion called gravity. Newton understood that gravity was a force of attraction between two objects. He also understood that an object with more matter or mass exerted the greater force or pulled smaller objects toward it. That meant that the large mass of the Earth pulled objects toward it. That is why the apple fell down instead of up and why people don’t float in the air.

He also thought that maybe gravity was not just limited to the Earth and the objects on the earth. What if gravity extended to the Moon and beyond? Newton calculated the force needed to keep the Moon moving around the earth. Then he compared it with the force that made the apple fall downward. After allowing for the fact that the Moon is much farther from the Earth and has a much greater mass, he discovered that the forces were the same and that the Moon is also held in orbit around Earth by the pull of earth’s gravity.

Disputes in Later Years and Death

Newton moved to London in 1696 to accept the position of warden of the Royal Mint. For many years afterward, he argued with Robert Hooke over who had actually discovered the connection between elliptical orbits and the inverse square law, a dispute that ended only with Hooke's death in 1703.

In 1705, Queen Anne bestowed a knighthood upon Newton, and thereafter he was known as Sir Isaac Newton. He continued his work, particularly in mathematics. This led to another dispute in 1709, this time with German mathematician Gottfried Leibniz. They both quarreled over which of them had invented calculus.

One reason for Newton's disputes with other scientists was his overwhelming fear of criticism, which led him to write, but then postpone publication of, his brilliant articles until after another scientist created similar work. Besides his earlier writings, "De Analysi" (which didn't see publication until 1711) and "Principia" (published in 1687), Newton's publications included "Optics" (published in 1704), "The Universal Arithmetic" (published in 1707), the "Lectiones Opticae" (published in 1729), the "Method of Fluxions" (published in 1736), and the "Geometrica Analytica" (printed in 1779).

On March 20, 1727, Newton died near London. He was buried in Westminster Abbey, the first scientist to receive this honor. 

Newton’s calculations changed the way people understood the universe. Prior to Newton, no one had been able to explain why the planets stayed in their orbits. What held them in place? People had thought that the planets were held in place by an invisible shield. Newton proved that they were held in place by the sun’s gravity and that the force of gravity was affected by distance and mass. While he was not the first person to understand that the orbit of a planet was elongated like an oval, he was the first to explain how it worked.

Isaac Newton

Isaac Newton (1642-1727) was an English mathematician and physicist widely regarded as the single most important figure in the Scientific Revolution for his three laws of motion and universal law of gravity. Newton's laws became a fundamental foundation of physics, while his discovery that white light is made up of a rainbow of colours revolutionised the field of optics.

Isaac Newton was born on 25 December 1642. His family in Woolsthorpe, Lincolnshire, was of the yeomanry class, but it was clear that Isaac was destined for a career other than farming. Isaac's father died a few months before he was born, and his stepfather, a minister, died when he was 14. His mother was Hannah Ayscough, and her second husband insisted that Isaac be separated from his mother for a number of years. Some historians have read into this period of neglect the cause of Newton's notoriously prickly character and hypersensitivity to criticism later in life.

The young Isaac had a prodigious interest in all things mechanical, and he made several working models of his own, but he did not do particularly well at school. He was mischievous and once sent out into the night sky a series of candle-lit lanterns, which startled the local villagers into thinking a shower of comets was about to strike them down. An uncle of Isaac was adamant he was sent to study law at Trinity College, Cambridge, in June 1661. It was not law, though, but mathematics at which the young scholar excelled.

Isaac supplemented his orthodox education by taking private lessons with the mathematician and theologian Isaac Barrow (1630-1677). Barrow would later recommend Newton for his own soon-to-be-vacant chair at Trinity College. Newton graduated in April 1665, but any hope of a quick career launch was scuppered when there was an outbreak of the Black Death plague . Isaac was obliged to return to the family home in Woolthorpe for a year or more.

Newton's Approach to Knowledge

Isaac did not waste his year of forced seclusion as he launched into a series of scientific investigations, so much so that he described 1665 to 1666 as his "year of wonder" (Burns, 217). Newton discovered "the binomial theory, the differential and integral calculus, and the refraction of light, and he began to work out the theory of universal gravitation" ( ibid ). Heady stuff. Newton was determined to use all manner of methodologies and thinking, from alchemy to mechanical philosophy , in order to find out scientific truths that can be expressed mathematically. To this end, he relentlessly squirrelled away kernels of ancient and contemporary knowledge, experimentation, and even lore in a few select and very private leather-bound volumes, thus preserving his findings for later consumption when his scientific theories became clearer. As Newton himself once stated in a private letter, "If I have seen further it is by standing on the shoulders of giants" (Wootton, 341).

Newton was also a Protestant Christian (although an unorthodox one in private) and saw no conflict in his endeavours to explain why things happened the way they do in the physical world with the story of the Bible . Indeed, the imperfections of the physical world his theories proved all required, Newton said, a Creator to adjust them every now and then. Some Christians saw this as denying the perfection of the Creator, others saw it as support for having a Creator in the first place. For Newton, space was "an eminent effect of God ," and "he seems to have gone so far as to later identify space with the immensity of God, so that the biblical pronouncements that 'In Him we live, and move, and have our being' (Acts 17:28) was taken quite literally" (Henry, 89).

Like many thinkers of the time, Newton was convinced that great knowledge had been gained and then lost over the centuries and so careful research of past intellectual endeavours was essential in order to recapture this lost wisdom (known as prisca sapientia ). This belief in a lost or secret knowledge – a peculiar eccentricity for a scientist – may also explain why Newton was notoriously reticent to publish his own discoveries. He seemed to relish secrecy, just as was the tradition of the great alchemists of the Middle Ages. Fortunately for the progress of humanity, Newton did eventually make his ground-breaking research public.

Newton's Spectrum of Light

Newton did not find the esteemed Royal Society very receptive to his new ideas, particularly on optics, and so he got his foot in the door of that institution by designing a reflective telescope in 1668. This type of telescope used a curved mirror made of a tin and copper alloy, which improved the clarity of the image seen by reducing chromatic aberration, that is, when all colours fail to converge in a single point (a problem of glass lenses at the time). Newton's telescope had a magnification of 40 times and was ten times shorter than the standard refracting telescope of the same strength would have been. The Royal Society was hooked, and Newton was elected to that learned body in 1672; he then submitted his research on optics, which had, in fact, made his super-duper telescope possible.

Between 1666 and 1668, Newton had conducted optical experiments where he captured a narrow beam of light through an aperture, which was then projected onto a wall in a dark room. The light was made to shine through a prism. Others had done this sort of thing before, but, significantly, Newton put his prism near the hole and far from the wall on which was projected a block of rainbow colours: red, orange, yellow, green, blue, indigo, and violet. Even more crucial – in what he called his experimentum crucis – Newton then had various colour beams of the split white light go through a second prism, and these left that second prism the same colour as they entered, i.e. they could not be split further. Newton was thus able to develop a new theory of light, which was that white light is made up of a spectrum of different colours, each with a different angle of refraction, just like a rainbow one could see in the sky after a shower of rain. In the rainbow in the sky, drops of water function as a prism, that is, the white light is refracted. Newton also discovered that in the tiny airspace between a lens and a sheet of glass, coloured concentric rings can be seen, and these are now called Newton's rings.

Newton's idea of heterogeneous light, published in Philosophical Transactions in 1672, went directly against the standard theory of the time, which was the inverse of Newton's. Champions of the standard theory included Robert Hooke (1635-1703), who dismissed Newton's theory and later even accused him of plagiarism (without foundation). Newton, who was "of somewhat paranoid temperament" (Burns, 73) and "socially dysfunctional" (Jardine, 36), promptly withdrew from the Royal Society and would not even accept its presidency until Hooke had departed this earth. In 1704, Newton finally published his work on light in detail in his Optics . It took some time for Newton's theory to become widely accepted, but it is now a cornerstone of the science of optics.

Newton's Law of Gravity

The German astronomer Johannes Kepler created the most accurate yet system of planetary astronomy, with the heavenly bodies moving in elliptical orbits around the Sun and not the traditional model of perfect circles as proposed by thinkers from Claudius Ptolemy (c. 100 to c. 170) to Nicolaus Copernicus (1473-1543). The discovery that the planets increased their speed as they drew closer to the Sun was essential for Newton to build his own work upon. Newton's law of gravity would provide the cause for Kepler's keen observations of elliptical planetary motions. Encouraged, both with words and money, by his good friend Edmund Halley (1656-1742), Newton finally presented his theory of gravity in Mathematical Principles of Natural Philosophy ( Philosophiae Naturalis Principia Mathematica ), published in 1687.

The effects of gravity have been known since antiquity. Ancient thinkers formed theories as to why objects fell to the ground, the most common being that this was because Earth was the very centre of the universe and so some mysterious force attracted all objects to the central point. Similarly, thinkers like Galileo Galilei (1564-1642) had pondered what kind of force was responsible for the Sun seemingly pulling orbiting planets more speedily to its centre the closer they got to it. Magnetism was often suggested as the answer, but many thinkers remained unconvinced.

An apple may not have actually fallen from a branch and hit Newton on the head, but it does seem that his observation of fruit falling set him pondering what force was involved and how to measure it. Newton had also noticed many other 'attractions' and 'repulsions' between many other objects and substances, and so he began to formulate a theory that could measure such phenomena and finally bring together (or at least reconcile) two ancient but often opposing strands of human thought: mechanics and mathematics.

In his Principia , Newton put forward his theory of universal gravitation, but first, he presented a system of mathematical laws, which became known as 'Newton's laws of motion', here summarised by W. E. Burns:

That there is an attractive force between bodies that varies with the inverse square of the distance between them – and Newton's three laws of motion – 1. a body at rest or in motion in a straight path will tend to stay in that state, 2. a change of motion in a body varies with the force impressed, and 3. each action has an equal and opposite reaction. (218)

Newton then presented his theory of gravity:

That between any two bodies in the universe there exists a force directly proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance. (Burns, 245)

Newton's theory of gravity was universal because it applied to everything from spinning planets to the movement of comets to the tides of the sea to that apocryphal apple dropping from a tree. The law of gravity (actually called a 'law' by Newton only in his later Optics ) applied equally to terrestrial affairs and to the heavens. Newton could now make accurate predictions of the effects of gravity. This was a new science. Of course, not everyone immediately adopted Newton's theories. The mechanical philosophers and the Cartesian followers of René Descartes (1596-1650), for example, could not accept that one physical body can affect another body without something, a third element, touching the two. Put simply, gravity was rather mysterious, since nobody, not even Newton, knew where it came from, why it exists, and who or what ensures its persistence. Contemplation on this fact and the inference that these forces act without any consideration of humanity led in some ways to a disenchantment regarding a new and pitiless world, at least for those who did not believe that a god of some kind was behind it all.

Recognition: The Greatest Scientist

Newton's work on gravity was ultimately well received, particularly in England , and he was made a fellow of Trinity College in 1687. Two years later, Newton became the Lucasian Professor of Mathematics there. A circle of devoted international followers sprang up around Newton, including the Swiss mathematician Nicolas Fatio de Duillier (1664-1753), who became very close to him. From 1688, Newton became ambitious to forge a political career. The scientist had hoped to move to London but suffered a nervous breakdown in 1693, perhaps because of the end of his relationship with Fatio de Duillier but certainly made worse by his chronic insomnia and possibly even a consequence of mercury poisoning, a key ingredient of Newton's experiments in alchemy. Recovered by 1696, Newton was made the warden of the royal mint in the Tower of London , which carried with it both prestige and a handsome salary. Newton, taking a hands-on approach which had not been required for what was, in effect, an honorary position, impressed his employers so much that he was made the mint master in 1699. He performed the role with remarkable dedication for the next 28 years, much to the chagrin of the countless counterfeiters he identified (who were then invariably hanged).

It was also in 1699 that Newton was appointed a member of the French Royal Academy of Sciences, the first foreigner to gain entry. In 1703, he was elected President of the Royal Society, and he used his position to skew the society's endeavours much more towards practical experimentation (as opposed to merely reading the academic papers of others) throughout his tenure, which ended in 1727. Less admirable was his ongoing feud with the German mathematician Gottfried Wilhelm Leibniz , which significantly held back mathematics in Britain . Newton accused Leibniz of plagiarising his work on the calculus (a mathematical tool for calculating curves and their areas). In reality, both men had developed the calculus independently, and although most historians consider Newton to have got there first, Leibniz's version was superior. Newton was knighted by Anne, Queen of Great Britain (r. 1702-1714) in 1705, probably more for his service in the royal mint than his tremendous contribution to science, but, nevertheless, it was a memorable moment for all scientists past and present since he was the first to be so honoured.

Death & Legacy

Newton was famous in his own lifetime for his discoveries, as we have seen with his various appointments to prestigious institutions at home and abroad. Rather oddly for a man so associated with science, Newton spent his final years studying biblical prophecies, an area he believed was just as valid as scientific experimentation. Sir Isaac Newton died of kidney failure on 20 March 1727; he was 84 years old. He had never married and left no children. Newton was given a state funeral and buried in Westminster Abbey. Alexander Pope provided the memorable epitaph:

Nature and Nature's Laws lay hid by Night: GOD said, Let Newton be! And all was Light. (Wootton, 361)

Newton, in one of those statements he frequently made where one wonders if he is being genuinely modest, remarked upon his career and discoveries in the following terms:

I don't know what I may seem to the world but, as to myself, I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me. (Gleick, 4)

There would be many more breakthroughs in science after Newton, but nothing as revolutionary as his work until the development in the 20th century of relativity and quantum physics.

There developed a definite movement, known as Newtonianism, which pushed the idea that scientific knowledge should be presented as a series of mathematical laws which could predict tendencies of motion in relation to hypothetical accelerative forces. In addition, because Newton's research was so complex and inaccessible to the majority, a great number of writers sprang up who simplified Newton's work so that it could be understood by the reasonably well-educated. Newtonianism gradually spread across Europe to become the dominant approach in universities and amongst intellectuals. Newton's approach to knowledge, spread to new minds by such thinkers as Voltaire (1694-1778) in his Elements of Newton's Philosophy (1738), was an important part of the Enlightenment movement, where the improvement of the human condition became the ultimate goal of philosophy and science, despite Newton having split those two disciplines apart forever. Even that great modern genius Albert Einstein (1879-1955), with his new theory of relativity, could not overthrow Newtonianism but only extend it to new and bold horizons. As Einstein once said of Newton: "He stands before us strong, certain, and alone" (Gleick, 9).

Sir Isaac Newton contributed significantly to the field of science over his lifetime. He invented calculus and provided a clear understanding of optics. But his most significant work had to do with forces, and specifically with the development of a universal law of gravitation and his laws of motion . 

Isaac Newton was born on Christmas Day to a poor farming family in Woolsthorpe, England, in 1642. At the time of Newton's birth England used the Julian calendar, however, when England adopted the Gregorian calendar in 1752, his birthday became 4th January 1643. 

Isaac Newton arrived in the world only a few months after his father, Isaac Newton Sr, had died. "The boy expected to live managing the farm in the place of the father he had never known," wrote James Gleick in "Isaac Newton" ( Vintage, 2004 ). 

However, when it became clear a farming life was not for him, Newton attended Trinity College in Cambridge, England. "He did not know what he wanted to be or do, but it was not tend sheep or follow the plough and the dung cart," wrote Gleick. While there, he took an interest in mathematics, optics, physics, and astronomy . 

After his graduation, he began to teach at the college and was appointed as the second Lucasian Chair there. Today, the chair is considered the most renowned academic chair in the world, held by the likes of Charles Babbage and Stephen Hawking .

In 1689, Newton was elected as a member of parliament for the university. In 1703, he was elected as president of the Royal Society, a fellowship of scientists that still exists today. He was knighted by Queen Anne in 1705. He never married.

What are Isaac Newton's laws of motion?

Newton's most famous work came with the publication of his " Philosophiae Naturalis Principia Mathematica " ("Mathematical Principles of Natural Philosophy"), generally called Principia. In it, he determined the three laws of motion for the universe .

Newton's first law describes how objects move at the same velocity unless an outside force acts upon them. (A force is something that causes or changes motion.) Thus, an object sitting on a table remains on the table until a force — the push of a hand, or gravity — acts upon it. Similarly, an object travels at the same speed unless it interacts with another force, such as friction.

His second law of motion provided a calculation for how forces interact. The law states that a force is equal to the change in the momentum (mass multiplied by velocity) per change in time. Therefore, when more force is applied to an object, its acceleration also increases, but when the mass of the object increases and the force remains constant, its acceleration decreases.

Newton's third law states that for every action in nature, there is an equal and opposite reaction. If one body applies a force on a second, then the second body exerts a force of the same strength on the first, in the opposite direction. 

From all of this, Newton calculated the universal law of gravitation. He found that as two bodies move farther away from one another, the gravitational attraction between them decreases by the inverse of the square of the distance. Thus, if the objects are twice as far apart, the gravitational force is only a fourth as strong; if they are three times as far apart, it is only a ninth of its previous power.

These laws helped scientists understand more about the motions of planets in the solar system , and of the moon around Earth.

Related: What makes Newton's laws work? Here's the simple trick.

A popular myth tells of an apple falling from a tree in Newton's garden, which brought Newton to an understanding of forces, particularly gravity. Whether the incident actually happened is unknown, but historians doubt the event — if it occurred — was the driving force in Newton's thought process.

The myth tells of Isaac Newton having returned to his family farm in Woolsthorpe, escaping Cambridge for a short time as it was dealing with a plague outbreak. As he sat in the farm's orchard, an apple fell from one of the trees (in some tellings it hit Newton on the head). Watching this happen, Newton began to consider the forces that meant the apple always fell directly towards the ground, beginning his examination of gravity.

One of the reasons that this story gained a foothold in popular understanding is that it is an anecdote Newton himself seems to have shared. "Toward the end of his life, Newton told the apple anecdote around four times, although it only became well known in the nineteenth century," wrote Patricia Fara, a historian of science at the University of Cambridge, in a chapter of " Newton's Apple and Other Myths about Science " (Harvard University Press, 2020).

However, it would be at least 20 years before Newton published his theories on gravity. It seems more likely that Newton used the story as a means of connecting the concept of gravity's impact on objects on Earth with its impact on objects in space for his contemporary audience.

The apple tree in question — known as the "Flower of Kent" — still blooms in the orchard of Woolsthorpe Manor, and is now a popular tourist attraction.

— Physicists crack unsolvable three-body problem using drunkard's walk  

While a student, Newton was forced to take a two-year hiatus when plague closed Trinity College. At home, he continued to work with optics, using a prism to separate white light, and became the first person to argue that white light was a mixture of many types of rays, rather than a single entity. He continued working with light and color over the next few years and published his findings in " Opticks " in 1704.

Disturbed by the problems with telescopes at the time, he invented the reflecting telescope, grinding the mirror and building the tube himself. Relying on a mirror rather than lenses, the telescope presented a sharper image than refracting telescopes at the time. Modern techniques have reduced the problems caused by lenses, but large telescopes such as the James Webb Space Telescope use mirrors. 

As a student, Newton studied the most advanced mathematical texts of his time. While on hiatus, he continued to study mathematics, laying the ground for differential and integral calculus. He united many techniques that had previously been considered separately, such as finding areas, tangents, and the lengths of curves. He wrote De Methodis Serierum et Fluxionum in 1671 but was unable to find a publisher.

Newton also established a cohesive scientific method, to be used across disciplines. Previous explorations of science varied depending on the field. Newton established a set format for experimentation still used today.

However, not all of Newton's ideas were quite as revolutionary. In P rincipia, Newton describes how rarefied vapor from comet tails is pulled into Earth's gravitational grasp and enables the movements of the planet's fluids along with the "most subtle and useful part of our air, and so much required to sustain the life of all things with us."

How did Sir Isaac Newton die?

Newton died in 1727 during his sleep at the age of 84. Although the cause of death is unknown, a 1979 study published by Newton's own Royal Society suggests mercury poisoning may have contributed to the decline of his physical and mental health. During the exhumation of his body, large amounts of mercury were found in the scientist's system, likely due to his work with alchemy. Newton conducted several experiments to convert base metals, such as mercury and copper into precious metals, such as gold and silver. 

"In 1693 Newton suffered from insomnia and poor digestion; and he also wrote irrational letters to friends. Although most scholars have attributed Newton's breakdown to psychological factors, it is possible that mercury poisoning may have been the principal cause," wrote L. W. Johnson and M. L. Wolbarsht " Mercury Poisoning: A probable cause of Isaac Newton's physical and mental ills: Notes and Records of the Royal Society of London Vol. 34. No. 1. " .

After his death, his body was moved to a more prominent place in Westminster Abbey. His white and grey marble monument stands in the nave of the Abbey's choir screen and boasts sculptures of Newton lounging surrounded by children using the many instruments, such as telescopes, associated with Newton's work. The inscription on the monument — originally written in Latin — reads: 

" Here is buried Isaac Newton, Knight, who by a strength of mind almost divine, and mathematical principles peculiarly his own, explored the course and figures of the planets, the paths of comets, the tides of the sea, the dissimilarities in rays of light, and, what no other scholar has previously imagined, the properties of the colours thus produced. Diligent, sagacious and faithful, in his expositions of nature, antiquity and the holy Scriptures, he vindicated by his philosophy the majesty of God mighty and good, and expressed the simplicity of the Gospel in his manners. Mortals rejoice that there has existed such and so great an ornament of the human race! He was born on 25th December 1642, and died on 20th March 1726. " The date of his death on his monument is given in the Julian calendar.

Biography Sir Isaac Newton

Early Life of Newton

Sir Isaac Newton was born on Christmas Day, in 1643, to a relatively poor farming family. His father died three months before he was born. His mother later remarried, but her second husband did not get on with Isaac; leading to friction between Isaac and his parents. The young Isaac attended school at King’s School, Grantham in Lincolnshire (where his signature is still inscribed on the walls.) Isaac was one of the top students, but before completing his studies his mother withdrew him from school, so Isaac could work as a farmer. It was only through the intervention of the headmaster that Isaac was able to return to finish his studies; he passed his final exams with very good results and was able to go to Trinity College, Cambridge.

Newton at Cambridge

Sir Isaac Newton, has been referred to as one of the greatest geniuses of history. His mathematical and scientific achievements give credence to such a view. His many accomplishments in the field of science include:

Developing a theory of calculus . Unfortunately, at the same time as Newton, calculus was being developed by Leibniz.  When Leibniz published his results, there was a bitter feud between the two men, with Newton claiming plagiarism. This bitter feud lasted until Leibniz death in 1713, it also extended between British mathematicians and the continent.

Mathematical achievements of Newton

• Generalized binomial theorem
• Newton’s identities,
• Newton’s method,
• Classified cubic plane curves (polynomials of degree three in two variables),
• Substantial contributions to the theory of finite differences,
• Use of fractional indices
• Used geometry to derive solutions to Diophantine equations.
• Used power series with confidence and to revert power series.
• Discovered a new formula for pi.

Scientific Achievements of Newton

• Optics – Newton made great advancements in the study of optics. In particular, he developed the spectrum by splitting white light through a prism.
• Telescope – Made significant improvements to the development of the telescope. However, when his ideas were criticised by Hooke, Newton withdrew from the public debate. He developed an antagonistic and hostile attitude to Hooke, throughout his life.
• Mechanics and Gravitation . In his famous book Principia Mathematica . (1687) Newton explained the three laws of motion that laid the framework for modern physics. This involved explaining planetary movements.

Newton hit on the head with an Apple

The most popular anecdote about Sir Isaac Newton is the story of how the theory of gravitation came to him, after being hit on the head with a falling apple. In reality, Newton and his friends may have exaggerated this story. Nevertheless, it is quite likely that seeing apples fall from trees may have influenced his theories of gravity.

Newton’s Religious Beliefs

As well as being a scientist, Newton actually spent more time investigating religious issues. He read the Bible daily, believing it to be the word of God. Nevertheless, he was not satisfied with the Christian interpretations of the Bible. For example, he rejected the philosophy of the Holy Trinity; his beliefs were closer to the Christian beliefs in Arianism (basically there was a difference between Jesus Christ and God)

Newton – Bible Code

Newton was fascinated with the early Church and also the last chapter of the Bible Revelations. He spent many hours poring over the Bible, trying to find the secret Bible Code. He was rumoured to be a Rosicrucian. The religious beliefs that Newton held could have caused serious embarrassment at the time. Because of this, he kept his views hidden, almost to the point of obsession. This desire for secrecy seemed to be part of his nature. It was only on his death that his papers were opened up. The bishop who first opened Newton’s box, actually found them too shocking for public release, therefore, they were kept closed for many more years.

Newton and Alchemy

Newton was also interested in alchemy. He experimented on many objects, using a lot of Mercury. Very high levels of mercury in his bloodstream may have contributed to his early death and irregularities in later life.

Newton was made a member of the Royal Society in 1703. He was also given the job of Master of Mint in 1717. He took this job seriously and unofficially was responsible for moving England from the silver standard to the gold standard.

Newton was an extraordinary polymath; the universe simply fascinated him. He sought to discover the hidden and outer mysteries of life. With his sharp intellect and powers of concentration, he was able to contribute to tremendous developments in many areas of science. He was a unique individual. John Maynard Keynes , a twentieth-century genius, said of Newton:

“I do not think that any one who has pored over the contents of that box which he packed up when he finally left Cambridge in 1696 and which, though partly dispersed, have come down to us, can see him like that. Newton was not the first of the age of reason. He was the last of the magicians, the last of the Babylonians and Sumerians, the last great mind which looked out on the visible and intellectual world with the same eyes as those who began to build our intellectual inheritance rather less than 10,000 years ago. Isaac Newton, a posthumous child born with no father on Christmas Day, 1642, was the last wonderchild to whom the Magi could do sincere and appropriate homage.” [1]

9 Best Isaac Newton Books and Biographies

Isaac Newton’s name is synonymous with the scientific revolution of the 17th century. Newton contributed significantly to the fields of mathematics , physics, and astronomy, and his discoveries continue to influence modern scientific research. If you’re interested in learning more about Newton’s life and work, there are many excellent books to choose from. In this article, we’ll explore some of the best Isaac Newton books to read.

Understanding Isaac Newton’s Contributions to Science and Mathematics

Isaac Newton is widely considered one of the most influential scientists in history. His contributions to science and mathematics have had a profound impact on our understanding of the world around us. In this article, we will explore some of Newton’s most significant contributions and their practical applications.

Newton’s Laws of Motion

One of Newton’s most significant contributions to science is his three laws of motion. These laws explain the relationship between an object’s motion and the forces acting on it. The first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The second law states that the force acting on an object is equal to its mass times its acceleration. The third law states that for every action, there is an equal and opposite reaction.

Newton’s laws of motion have practical applications in many fields, from engineering to sports. For example, engineers use these laws to design cars, airplanes, and bridges that are safe and efficient. Athletes use them to improve their performance in sports such as gymnastics, diving, and figure skating.

If you want to learn more about Newton’s laws of motion, we recommend reading “Newton’s Laws of Motion” by Subodh Mahanti. This book offers a thorough, accessible explanation of Newton’s work and features many helpful illustrations and diagrams.

The Universal Law of Gravitation

Another of Newton’s most famous contributions is the universal law of gravitation. This law states that every particle in the universe attracts every other particle with a force proportional to their masses and the distance between them. In other words, the greater the mass of an object, the greater its gravitational pull, and the farther apart two objects are, the weaker their gravitational attraction.

The universal law of gravitation has had a profound impact on our understanding of the universe. It has helped us explain phenomena such as the orbits of planets around the sun, the tides, and the behavior of black holes.

If you want to learn more about Newton’s work in gravity, we recommend reading “ Newton and the Counterfeiter ” by Thomas Levenson. This book delves into the story of Newton’s quest to root out counterfeiters while exploring his groundbreaking work in gravity. It is a fast-paced, engaging read that weaves together intellectual history and true crime .

Calculus and its Applications

Calculus is another area in which Newton made crucial contributions. He invented calculus simultaneously with German mathematician Gottfried Wilhelm Leibniz, and the two are generally credited with its creation. Calculus is a branch of mathematics that deals with rates of change and slopes of curves.

Calculus has practical applications in many fields, from physics to economics. For example, physicists use calculus to study the motion of objects, while economists use it to study the behavior of markets and economies.

If you want to learn more about calculus, we recommend reading “ Calculus Made Easy ” by Silvanus P. Thompson. This book teaches the basics of calculus without getting bogged down in excessive mathematical jargon. It is written in accessible language and features many helpful examples and exercises.

In conclusion, Isaac Newton’s contributions to science and mathematics have had a profound impact on our understanding of the world around us. His laws of motion, universal law of gravitation, and work in calculus continue to be studied and applied today.

Isaac Newton’s Most Influential Works

Isaac Newton is widely regarded as one of the most influential scientists in history. His contributions to the fields of physics and mathematics are still studied and admired today. In this article, we will take a closer look at three of his most significant works.

Philosophiæ Naturalis Principia Mathematica

“ Philosophiæ Naturalis Principia Mathematica ,” often referred to simply as the “Principia,” is Newton’s masterpiece and one of the most significant works in the history of science. In it, he lays out his laws of motion and theory of gravity. For readers interested in engaging directly with Newton’s work, the “Principia” is an obvious choice. In “ The Principia: The Authoritative Translation and Guide ” by I. Bernard Cohen and Anne Whitman, readers can explore the “Principia” with the help of a modern translation and extensive annotations.

The “Principia” is not only a scientific work but also a philosophical one. Newton’s ideas about the nature of the universe and the role of mathematics in understanding it were groundbreaking. His laws of motion and theory of gravity revolutionized the way scientists understood the physical world and laid the foundation for modern physics.

Opticks: Or, A Treatise of the Reflections, Refractions, Inflections and Colours of Light

Newton’s work on optics also made significant contributions to the field of physics. In “ Opticks: Or, A Treatise of the Reflections, Refractions, Inflections and Colours of Light ,” Newton explores the properties of light and offers a scientific explanation for many optical phenomena. The book is fascinating both for its historical significance and for the beauty of its prose.

One of the most interesting aspects of “Opticks” is Newton’s experiments with prisms. He discovered that white light is actually made up of different colors and that each color has a different wavelength. This discovery led to the development of the modern theory of color and the understanding of how light interacts with matter.

The Chronology of Ancient Kingdoms Amended

Although less well-known than his work in math and physics, Newton also made contributions to the field of history. In “ The Chronology of Ancient Kingdoms Amended ,” Newton argues that the timeline of ancient history needs to be revised based on new astronomical observations. The book is a fascinating glimpse into a lesser-known area of Newton’s intellectual pursuits.

Newton’s approach to history was heavily influenced by his scientific background. He believed that historical events could be understood and explained through careful observation and analysis, just like scientific phenomena. His work on the chronology of ancient kingdoms challenged traditional views of history and paved the way for a more scientific approach to the study of the past.

Overall, Isaac Newton’s contributions to science and mathematics are immeasurable. His work laid the foundation for modern physics and helped shape our understanding of the universe. His legacy continues to inspire scientists and scholars today.

Isaac Newton

By: History.com Editors

Updated: October 16, 2023 | Original: March 10, 2015

Isaac Newton is best know for his theory about the law of gravity, but his “Principia Mathematica” (1686) with its three laws of motion greatly influenced the Enlightenment in Europe. Born in 1643 in Woolsthorpe, England, Sir Isaac Newton began developing his theories on light, calculus and celestial mechanics while on break from Cambridge University. 

Years of research culminated with the 1687 publication of “Principia,” a landmark work that established the universal laws of motion and gravity. Newton’s second major book, “Opticks,” detailed his experiments to determine the properties of light. Also a student of Biblical history and alchemy, the famed scientist served as president of the Royal Society of London and master of England’s Royal Mint until his death in 1727.

Isaac Newton: Early Life and Education

Isaac Newton was born on January 4, 1643, in Woolsthorpe, Lincolnshire, England. The son of a farmer who died three months before he was born, Newton spent most of his early years with his maternal grandmother after his mother remarried. His education was interrupted by a failed attempt to turn him into a farmer, and he attended the King’s School in Grantham before enrolling at the University of Cambridge’s Trinity College in 1661.

Newton studied a classical curriculum at Cambridge, but he became fascinated by the works of modern philosophers such as René Descartes, even devoting a set of notes to his outside readings he titled “Quaestiones Quaedam Philosophicae” (“Certain Philosophical Questions”). When the Great Plague shuttered Cambridge in 1665, Newton returned home and began formulating his theories on calculus, light and color, his farm the setting for the supposed falling apple that inspired his work on gravity.

Isaac Newton’s Telescope and Studies on Light

Newton returned to Cambridge in 1667 and was elected a minor fellow. He constructed the first reflecting telescope in 1668, and the following year he received his Master of Arts degree and took over as Cambridge’s Lucasian Professor of Mathematics. Asked to give a demonstration of his telescope to the Royal Society of London in 1671, he was elected to the Royal Society the following year and published his notes on optics for his peers.

Through his experiments with refraction, Newton determined that white light was a composite of all the colors on the spectrum, and he asserted that light was composed of particles instead of waves. His methods drew sharp rebuke from established Society member Robert Hooke, who was unsparing again with Newton’s follow-up paper in 1675. 

Known for his temperamental defense of his work, Newton engaged in heated correspondence with Hooke before suffering a nervous breakdown and withdrawing from the public eye in 1678. In the following years, he returned to his earlier studies on the forces governing gravity and dabbled in alchemy.

Isaac Newton and the Law of Gravity

In 1684, English astronomer Edmund Halley paid a visit to the secluded Newton. Upon learning that Newton had mathematically worked out the elliptical paths of celestial bodies, Halley urged him to organize his notes. 

The result was the 1687 publication of “Philosophiae Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy), which established the three laws of motion and the law of universal gravity. Newton’s three laws of motion state that (1) Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it; (2) Force equals mass times acceleration: F=MA and (3) For every action there is an equal and opposite reaction.

“Principia” propelled Newton to stardom in intellectual circles, eventually earning universal acclaim as one of the most important works of modern science. His work was a foundational part of the European Enlightenment .

With his newfound influence, Newton opposed the attempts of King James II to reinstitute Catholic teachings at English Universities. King James II was replaced by his protestant daughter Mary and her husband William of Orange as part of the Glorious Revolution of 1688, and Newton was elected to represent Cambridge in Parliament in 1689. 

Newton moved to London permanently after being named warden of the Royal Mint in 1696, earning a promotion to master of the Mint three years later. Determined to prove his position wasn’t merely symbolic, Newton moved the pound sterling from the silver to the gold standard and sought to punish counterfeiters.

The death of Hooke in 1703 allowed Newton to take over as president of the Royal Society, and the following year he published his second major work, “Opticks.” Composed largely from his earlier notes on the subject, the book detailed Newton’s painstaking experiments with refraction and the color spectrum, closing with his ruminations on such matters as energy and electricity. In 1705, he was knighted by Queen Anne of England.

Isaac Newton: Founder of Calculus?

Around this time, the debate over Newton’s claims to originating the field of calculus exploded into a nasty dispute. Newton had developed his concept of “fluxions” (differentials) in the mid 1660s to account for celestial orbits, though there was no public record of his work. 

In the meantime, German mathematician Gottfried Leibniz formulated his own mathematical theories and published them in 1684. As president of the Royal Society, Newton oversaw an investigation that ruled his work to be the founding basis of the field, but the debate continued even after Leibniz’s death in 1716. Researchers later concluded that both men likely arrived at their conclusions independent of one another.

Death of Isaac Newton

Newton was also an ardent student of history and religious doctrines, and his writings on those subjects were compiled into multiple books that were published posthumously. Having never married, Newton spent his later years living with his niece at Cranbury Park near Winchester, England. He died in his sleep on March 31, 1727, and was buried in Westminster Abbey .

A giant even among the brilliant minds that drove the Scientific Revolution, Newton is remembered as a transformative scholar, inventor and writer. He eradicated any doubts about the heliocentric model of the universe by establishing celestial mechanics, his precise methodology giving birth to what is known as the scientific method. Although his theories of space-time and gravity eventually gave way to those of Albert Einstein , his work remains the bedrock on which modern physics was built.

• “If I have seen further it is by standing on the shoulders of Giants.”
• “I can calculate the motion of heavenly bodies but not the madness of people.”
• “What we know is a drop, what we don't know is an ocean.”
• “Gravity explains the motions of the planets, but it cannot explain who sets the planets in motion.”
• “No great discovery was ever made without a bold guess.”

PM Modi releases three books on Venkaiah Naidu says former Vice President's biography would inspire people

The books released include the biography of the former vice president titled venkaiah naidu – life in service, celebrating bharat – the mission and message of shri m venkaiah naidu as 13th vice president of india and mahaneta – life and journey of shri m venkaiah naidu..

Venkaiah Naidu, several other leaders and prominent personalities attended the event in Hyderabad.

These books will inspire people and show them the right direction

Speaking on the occasion, Modi said he is happy that he got the opportunity to release the books and expressed confidence that the former Vice President's biography would inspire people. He further said thousands of party workers, including himself, got the opportunity to learn from Naidu.

"Tomorrow, 1st July, is Venkaiah Naidu's birthday. His life journey is completing 75 years. These 75 years have been of extraordinary achievements. These 75 years have been of amazing milestones. I am happy that today I have got the opportunity to release his biography as well as 2 more books. I believe that these books will inspire people and show them the right direction of national service. I have had the opportunity to work with Venkaiah Naidu for a very long time. When he was the national president of the party, when he was a senior cabinet colleague in the government when he was the Vice President of the country and the Chairman of the Rajya Sabha," said the Prime Minister. 

PM Modi further said that he was the only minister in India who worked for rural development during the time of Atal ji and worked with us as a senior colleague in the cabinet as the Urban Development Minister.

"It has been 50 years since the Emergency was imposed by Congress by tarnishing the prestige of the Constitution. Venkaiah ji was among those who fought against the Emergency and at that time Venkaiah ji was in jail for about 17 months. I consider him as my true comrade who was tested in the fire of Emergency. Power is not a means of happiness but a means of service and accomplishment of resolutions. Venkaiah ji proved this even when he got the opportunity to join Atal Bihari Vajpayee ji's government. Venkaiah ji knew that he would probably get any ministry he wished for, but he went ahead and said that it would be good if I was given the Rural Development Ministry. Naidu ji wanted to serve the villagers, poor and farmers. He was the only minister in India who worked for rural development during the time of Atal ji and worked with us as a senior colleague in the cabinet as the Urban Development Minister," he added. 

The books released by Prime Minister include:

• Biography of the former Vice President titled “Venkaiah Naidu – Life in Service” authored by Shri S Nagesh Kumar, former Resident Editor of The Hindu, Hyderabad edition
• “Celebrating Bharat – The Mission and Message of Shri M Venkaiah Naidu as 13th Vice–President of India”, a Photo chronicle compiled by Dr. I.V. Subba Rao, Former Secretary to Vice-President of India
• Pictorial biography in Telugu titled “Mahaneta – Life and Journey of Shri M. Venkaiah Naidu” authored by Shri Sanjay Kishore.

NIGHT FLYER: Harriet Tubman and the Faith Dreams of a Free People , by Tiya Miles

Harriet Tubman led such an eventful life — so filled with hardship, extreme peril and close calls — that even an atheist might find it hard to deny that her nine decades of survival on this Earth were nothing short of miraculous.

Tubman herself credited God with guiding her dangerous work as a conductor on the Underground Railroad during the 1850s; she made an estimated 13 trips below the Mason-Dixon line and spirited as many as 80 souls north, often all the way to Canada. Tubman’s own escape in 1849 was legendary. After a first attempt with her brothers, who were so frightened that they insisted on turning back to their enslaver’s estate near the Chesapeake Bay, an undaunted Tubman made the treacherous 90-mile journey from Maryland to Pennsylvania on her own.

“Where others saw shut doors and unscalable brick walls, she dreamed into being tunnels and ladders,” the historian Tiya Miles writes in “Night Flyer,” a short biography of Tubman that is the first in a new series, called Significations and edited by Henry Louis Gates Jr., about notable Black figures. For decades after her death in 1913, Tubman’s extraordinary life was mostly relegated to books for children and young adults. Thorough, probing biographies by the historians Catherine Clinton and Kate Clifford Larson were published two decades ago. More recently, Tubman was the subject of a Hollywood biopic and “She Came to Slay,” an illustrated volume by the historian Erica Armstrong Dunbar, featuring a drawing of a pistol-toting Tubman on the cover.

Perhaps inevitably, all the pop-cultural attention has been double-edged, commemorating Tubman’s formidable accomplishments while also making it harder to discern who she actually was. Miles admits that before she started this project, Tubman “had become a stock figure in my imagination, a known hero in the cast of characters that we might call the abolitionist avengers.” Recognizing Tubman’s idiosyncrasies and physical ailments “resizes Tubman the cultural icon to human scale.”

Miles calls “Night Flyer” a “faith biography,” emphasizing Tubman’s spirituality along with her ecological awareness, expressed as a profound attentiveness to the natural world. Miles also draws on the life stories of “similar women,” such as the preachers Jarena Lee and Zilpha Elaw , to try to illuminate some of the more interior experiences that Tubman took care to keep hidden.

Such gaps in the historical record are familiar to Miles. Having written about Indigenous people and African Americans, including in the National Book Award-winning “All That She Carried,” she frequently faces what she has called “the conundrum of the archives.” Tubman did not read or write; she dictated her life story to “typically white, middle-class, antislavery women,” like her first biographer, Sarah Bradford. Although usually “well-meaning,” Tubman’s amanuenses sometimes “demeaned” her, casting her as an exotic, almost otherworldly figure.

There are a number of haunting moments in the new biography Candy Darling: Dreamer, Icon, Superstar , written by critic and former Village Voice columnist Cynthia Carr. There’s the revelation that Peter Hujar, whose prolific and sensitive documentation of queer New York in the 1970s and ’80s includes a striking image of Darling on what became her deathbed, would die in that very same room 13 years later when the hospital floor was repurposed to care for those with HIV. Carr also reveals that Darling’s funeral was held in the same room of the Campbell Funeral Chapel on the Upper East Side as Judy Garland’s — a Hollywood connection Darling might have appreciated.

But perhaps most striking is a moment that comes early in the book. We learn that in the 1950s actress Christine Jorgensen , one of the most famous trans women of the 20th century, had moved into a house just a 30-minute walk from Darling’s childhood home in Massapequa Park, Long Island. “Candy would make her way over there, then walk back and forth in front of the house hoping to see Jorgensen appear,” Carr writes. “But she never did.”

Candy Darling would go on to appear in 10 films, most notably Andy Warhol’s 1971 Women in Revolt (directed by Paul Morrissey), as well as plays by Tennessee Williams, Jackie Curtis, and Tom Eyen. She was the subject of “Walk on the Wild Side” (1972), perhaps Lou Reed’s best-known song, and she inspired music and lyrics written by the Rolling Stones. She was photographed not only by Hujar, but also by the likes of Richard Avedon, Laura Rubin, and Francesco Scavullo, and she would be featured on the cover of After Dark magazine , in the pages of Esquire , Women’s Wear Daily , Photoplay , and multiple issues of Interview , among other publications. Despite her death in 1974 at the age of 29, due to lymphoma, her legacy has rippled across multiple generations, influencing artists ranging from Greer Lankton to Anohni to St. Vincent.

But the story that Carr brings to light of a young Darling is so palpable — ensconced in the brutal conformity of Long Island (birthplace of Levittown ), quietly hoping to encounter a trans foremother in person, perhaps seeking a bit of Jorgensen’s knowledge and experience in a world where most people refused to acknowledge the possibility of transgender existence, perhaps also hoping for a bit of her stardust (Jorgensen transmuted her extraordinarily public outing into a decades-long career as a performer, public speaker, and activist). But even without meeting her, Jorgensen must have offered some sense that Darling was not alone, that there was a precedent for her existence, and that one could achieve some measure of the fame she coveted.

Given the celebrity Darling did achieve, it’s notable that there hasn’t been a biography until now, 50 years after her passing. There is the 2009 documentary film Beautiful Darling , but it is littered throughout with both casual and vehement transphobia. The heavy influence on the film of Darling’s close friend and unreliable narrator Jeremiah Newton feels overbearing at times, though he does deserve credit for becoming the keeper of her physical archive and ashes when her mother, Theresa Slattery, sought to rid herself of them. He also went on to record countless interviews with people who knew Darling, creating an archive Carr acknowledges as crucial to her work on the book.

Darling herself, as Carr is careful to note, was an unreliable narrator whose obfuscations were widely acknowledged by those in her life, whether they be tall tales about how she’d spent an evening or fabrications about her upbringing. But the author emphasizes that Darling was not only in the position of having to craft her own existence but also of reckoning with the painful contradiction that, more often than not, her fame was attached to the public pigeonholing her as a drag queen or “transvestite,” and not as the woman she knew herself to be.

Unlike the documentary, Carr’s biography is extremely well-researched and deeply empathetic. Readers witness the relentless transphobia Darling faced, but also come to understand her fabulations and dissimulations as both coping mechanisms and a refusal to accept the limitations others tried to impose on her. With no home of her own at any point in her adulthood and largely without money, Darling’s existence was precarious, even as she walked into some of New York’s toniest parties on the arm of Warhol at the height of his fame.

That said, the fact that she was a lithe White woman who fit within the beauty standards of her time gave her entrée not available to many of her non-White trans contemporaries or those whose bodies don’t conform to entrenched and largely unattainable beauty standards. I don’t note this to critique Darling; she used what she had to survive. Instead I raise the point to critique a discriminatory society and, by extension, historical record. This book offers a rich and nuanced portrait of what it took to fly in the face of that society, and to do so with great style and flourish. It’s crucial to have full, compelling portraits of those who broke ground, proving that we can be both flawed and remarkable. And here we learn unquestionably that Darling was a remarkable woman.

Candy Darling: Dreamer, Icon, Superstar by Cynthia Carr (2024) is published by Farrar, Straus and Giroux and is available online and through independent booksellers.
