The Obsession

Isaac Newton

Newton spent more years on alchemy than on physics. This is not a rumour or a revisionist claim. When John Maynard Keynes bought Newton’s personal papers at auction in 1936, he read them overnight and the next morning told the Royal Society: “Newton was not the first of the age of reason. He was the last of the magicians.”

The papers ran to a million words. Recipes for transmuting metals. Diagrams of the philosopher’s stone. Notes on alchemical allegory in the Book of Revelation, which Newton believed encoded the end of the world with specific dates. He worked on this material from roughly 1666 until his death in 1727. Sixty-one years. For context, the Principia Mathematica — the book that invented classical mechanics and became the foundation of modern science — took him eighteen months, and he considered it a detour from his real work.

The real work, in his view, was to read the mind of God. Alchemy was one language God had used. Scripture was another. Mathematics was a third. Newton believed they all decoded to the same message if you could find the Rosetta Stone between them. He never found it. He tried every day until he died.

Talk to Newton and don’t expect focus. Or rather — expect too much focus, on things you didn’t come to discuss. Ask him about gravity and he’ll take forty minutes to get to your question, because he’ll first need to establish what Hermes Trismegistus wrote about corpuscles, why the ancient Egyptians knew more than his Cambridge colleagues, and how the temple of Solomon’s dimensions encode the relative masses of the celestial spheres. He isn’t changing the subject. To him, it is the subject. Gravity and alchemy were chapters of the same book.

He’ll inspect you the way he inspected everything — patiently, suspiciously, as though you might be hiding the answer. He lived alone. He died a virgin at 84. He wrote a list of 48 sins he’d committed, aged 19, including “Punching my sister” and “Threatening my mother and father Smith to burn them and the house over them.” He never made peace with the stepfather who sent him away at three. He never made peace with anyone who disagreed with him on anything. Hooke — who’d been dead for six years when Newton moved — had his portrait “lost” on the move. His rival Leibniz, who arguably invented calculus at the same time, was accused in a committee Newton personally organized, using evidence Newton personally wrote under other names.

The mind that discovered the laws of motion was not a well-adjusted mind. It was a mind that could not stop. The same engine that tore through motion and optics kept tearing, into metal, into scripture, into the prophecies of Daniel, because stopping was not available to him. What he wanted was to understand everything, and he’d rather have died trying than accepted partial answers.

You can try to change the subject. He’ll let you think you have.


Three questions to start with:

  • Alchemy or physics — which one was the real work, and which was the detour?
  • Hooke, Leibniz, Flamsteed. You destroyed all three. Any regrets?
  • You believed the Book of Revelation encoded the date of the end of the world. What year did your calculations give you?

Biography

Sir Isaac Newton was an English polymath who was a mathematician, physicist, astronomer, alchemist, theologian, author and inventor. He was a key figure in the Scientific Revolution and the Enlightenment that followed. His book Philosophiæ Naturalis Principia Mathematica, first published in 1687, achieved the first great unification in physics and established classical mechanics. Newton also made seminal contributions to optics, and shares credit with the German mathematician Gottfried Wilhelm Leibniz for formulating infinitesimal calculus, although he developed calculus years before Leibniz. Newton contributed to and refined the scientific method, and his work is considered the most influential in bringing forth modern science.

Timeline

The story of Isaac Newton, told in moments.

1643 Birth

Born premature on Christmas Day (Old Style calendar) at Woolsthorpe Manor, Lincolnshire. Small enough to fit in a quart mug, his mother said. His father, a farmer who couldn't sign his own name, died three months before.

1665 Life

The plague closes Cambridge. Newton retreats to Woolsthorpe for two years. Alone on the family farm, he develops calculus, experiments with prisms to split white light into colors, and begins thinking about gravity. He is 23. He tells no one.

1684 Event

Edmond Halley visits Newton in Cambridge and asks what shape a planet's orbit would take under an inverse-square law of gravity. Newton answers immediately: an ellipse. He'd solved it years ago and lost the paper. Halley persuades him to write it up.

1687 Event

Publishes the Principia. Three volumes. Halley pays for the printing out of his own pocket after the Royal Society spent its budget on a history of fish. The book unifies terrestrial and celestial mechanics into a single framework. It will dominate physics for over two centuries.

1693 Life

Suffers a nervous breakdown. Sends paranoid letters to friends accusing them of conspiracies. Stops doing science almost entirely. Some historians suspect mercury poisoning from his decades of alchemy experiments. Hair samples taken centuries later confirm toxic levels of mercury.

1696 Life

Leaves Cambridge for London to become Warden of the Royal Mint. Then Master. He personally hunts counterfeiters, interrogates suspects, and sends men to the gallows. He is ruthlessly effective at the job.

1704 Event

Publishes Opticks after waiting decades. He'd done the experiments in the 1660s and 70s. He delayed publication until Hooke was dead. Hooke had criticized his theory of light for thirty years.

1727 Death

Dies in his sleep in Kensington, London. He is 84. He never married. Never traveled abroad. Likely died a virgin. His body lay in state in Westminster Abbey for a week before burial. Voltaire, visiting England, attended the funeral and later wrote that Newton was buried "like a king who had done well by his subjects."

Show full timeline (12 entries)
1703 Life

Elected President of the Royal Society. He'll hold the position for 24 years, until his death. He uses it to settle scores, particularly against Robert Hooke and Gottfried Leibniz in the calculus priority dispute.

1705 Life

Knighted by Queen Anne at Trinity College, Cambridge. The first scientist to receive the honor.

1717 Life

Spends more time on alchemy and biblical chronology than physics. His unpublished alchemical writings total over a million words. He tries to calculate the date of the apocalypse. He settles on no earlier than 2060.

2016 Legacy

A handwritten copy of the Principia sells at auction for .7 million. Newton wrote fewer than 500 copies for the first edition. About 200 survive.

In Their Own Words (20)

Bullialdus wrote that all force respecting the Sun as its center & depending on matter must be reciprocally in a duplicate ratio of the distance from the center.

Letter to Edmund Halley (June 20, 1686) quoted in I. Bernard Cohen and George E. Smith, ed.s, The Cambridge Companion to Newton (2002) p. 204, 2002

One [method] is by a Watch to keep time exactly. But, by reason of the motion of the Ship, the Variation of Heat and Cold, Wet and Dry, and the Difference of Gravity in different Latitudes, such a watch hath not yet been made.

Written in remarks to the 1714 Longitude committee; quoted in Longitude (1995) by Dava Sobel, p. 52 (i998 edition) ), 1995

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 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.

Memoirs of the Life, Writings, and Discoveries of Sir Isaac Newton (1855) by Sir David Brewster (Volume II. Ch. 27). Compare: "As children gath'ring pebbles on the shore", John Milton, Paradise Regained, Book iv. Line 330, 1855

I keep the subject constantly before me, and wait 'till the first dawnings open slowly, by little and little, into a full and clear light.

Reply upon being asked how he made his discoveries, as quoted in "Biographia Britannica: Or the Lives of the Most Eminent Persons who Have Flourished in Great Britain from the Earliest Ages Down to the Present Times, Volume 5 ", by W. Innys, (1760), p. 3241. Fuller quote:, 1760

A good watch may serve to keep a recconing at Sea for some days and to know the time of a Celestial Observ[at]ion: and for this end a good Jewel watch may suffice till a better sort of Watch can be found out. But when the Longitude at sea is once lost, it cannot be found again by any watch.

Letter to Josiah Burchett (1721), quoted in Longitude (1995) by Dava Sobel, p. 60, 1721
