Newton's Other Side

Hi everyone, welcome to Cold-Knowledge Blind Box. The person we're talking about today is...

If he were around today, he would definitely count as an academic superstar. He's the name you couldn't avoid in school. Physics class covers mechanics and mentions him. Math class covers calculus and can't skip him. Even astronomy, when talking about universal gravitation, has to start with him. Yes, he is Isaac Newton, the man countless people call "the greatest scientist in human history." But you may not know that this scientific giant's life is far more dramatic than what the textbooks say. Before he turned 26 he had already made discoveries that changed the world, but after 30 he became obsessed with stock trading and turned into a "leek" (a sucker, as the slang goes), and he also put on a series of "academic palace dramas" with the great minds of his time. Today, let's set aside the "perfect Newton" from the textbooks and talk about a life that was both great and "real to the point of being uncomfortable."

(Sound effect: a soft rustle of turning pages)

First, let's talk about Newton's "cheat-code start." In 1665, a great plague broke out in London. Yes, you heard right, the famous "Great Plague of London," a disaster that killed more than 80,000 people, and the whole city was in a panic. At that time Newton, 22 years old, was studying at Trinity College, Cambridge. When the university saw the situation, it quickly sent the students home to avoid the disease. If that happened today, plenty of people would probably be stuck at home scrolling on their phones and ordering takeout. But who was Newton? He shut himself in the attic of his family home in the countryside and began a mode of "closed-door training."

Want to guess what he did during those 18 months? Let me put it this way: those two months were worth more research than most people's entire lives! First he came up with the "generalized binomial theorem," which later became a basic tool of advanced mathematics. Then, even more outrageously, he started working on calculus (yes, the subject that today's college students dread the most). Although it wasn't formally named yet, he had already thoroughly grasped its core ideas. More importantly, he set his sights on two "ultimate questions": first, why does an apple fall to the ground (which later led to universal gravitation), and second, what on earth is light (which later led to his theory of optics). Later, people called these 18 months Newton's "year of wonders," like a martial arts novel where the hero falls into a cave, finds a secret manual, and in one night opens all his blocked meridians. Except Newton's "secret manual" was his own brain.

When the plague ended, Newton went back to school to continue his studies, and he happened to take over the position of his teacher Barrow, becoming the Lucasian Professor of Mathematics at Cambridge. This title was no small thing. It was like the "academic throne" of Cambridge, and everyone who held it was a heavyweight. For example, Stephen Hawking, who wrote A Brief History of Time, held it for 30 years. You'd think such an impressive figure would have packed lecture halls, but Newton refused to play by the rules. His lectures were so "hardcore" that students couldn't follow them, and fewer and fewer people came to listen, until eventually almost no one signed up. You might think this would hurt his career. On the contrary! With no one bothering him, he became even more focused. He built the world's first "reflecting telescope," which was far clearer than the refracting telescopes of the time. He systematically organized his theories of optics. He was even invited by the Queen of England to tea. A true academic superstar.

But good days didn't last long. Newton soon ran into his lifelong nemesis, Robert Hooke. Hooke was no minor figure. He was a few years older than Newton, and at that time he was already a "heavyweight" in the Royal Society of England. He discovered "Hooke's law" (the one stating that the restoring force of a spring is proportional to its deformation). He was also a master of the microscope, and even the word "cell" was coined by him. Yes, the "cell" you learned about in biology class was first named by Hooke as he stared at a piece of cork. If the two had cooperated, they might have made even more great discoveries. But unfortunately, one had a hot temper and the other was a nitpicker, and when they came together it was like Mars crashing into Earth.

Their first clash was over optics. Newton believed light was made of "particles" (later called the "corpuscular theory"), while Hooke supported the "wave theory" (along with Huygens and his school). Newton wrote a paper to rebut him, and the very first paragraph directly named and insulted Hooke, which made Hooke furious: "What makes you think I'm wrong? I'm the grandfather of the microscope!" Even worse, Newton's great work Opticks, which he had been holding back for years, could have been published much earlier. But Hooke and Huygens teamed up to attack him, and Newton got so angry that he locked the manuscript in a drawer and didn't publish until after Hooke had died. By then Huygens had also passed away, and no one was left to argue with him. His "corpuscular theory" then dominated the scientific world for over 100 years, until Einstein proved "wave-particle duality" in 1905. (So it turned out that neither Newton nor Hooke had been entirely wrong.)

(Sound effect: low, dramatic narrative music)

The most famous conflict was over the "law of universal gravitation." Nowadays we love to tell the story of "Newton gets hit by an apple, then discovers universal gravitation." But honestly, that's probably made up. Newton's niece, wanting to brag about her uncle, invented the story that an apple hit him on the head, and later Voltaire embellished it in a book, and the whole world went along with it. In reality, Newton studied gravity because he had read Hooke's and other scientists' discussions about planetary motion. In particular, Hooke had already proposed the "inverse square law" (that gravitational force is inversely proportional to the square of the distance), but Hooke wasn't strong enough at math, so he could only make a rough guess.

Newton was different. He pulled out calculus, the great weapon, and in nine pages of paper he worked out that if gravity followed the inverse square law, then planetary orbits must be ellipses (which was later proven to be completely correct). He wrote his results up as Mathematical Principles of Natural Philosophy, which became the "bible" of science. But when it came time to publish, he needed financial help from his good friend Halley (the same Halley after whom Halley's Comet is named). By then Hooke wasn't having it: "I said the inverse square law long ago! You must have borrowed my ideas!" He asked Halley to plead with Newton on his behalf: "At least mention my name in the book, would you?" Newton reluctantly wrote a line in a note: "Hooke also discussed similar problems." But Hooke felt it wasn't enough and kept pushing the issue. Newton then went fully dark. In the second edition of the book, everything about Hooke was deleted. Hooke later died bitter and frustrated. And after Newton became president of the Royal Society, he used the society's move to destroy Hooke's manuscripts and portraits. Today we don't even know what Hooke looked like. Some guess that he was badly hunchbacked. And Newton's famous line, "If I have seen further, it is by standing on the shoulders of giants," which was actually written to Hooke, may have been a sarcastic jab: "With your hunched back, you couldn't even reach my shoulders!"

(Sound effect: a mocking chuckle)

Newton's skill at picking fights wasn't limited to Hooke, either. He also clashed with the director of the Greenwich Observatory, Flamsteed. This director spent 40 years observing 2,935 stars, with records so precise they were almost unbelievable, but because he was such a perfectionist, he kept delaying publication of his star catalogue. In 1680, two comets appeared in Europe. The director judged that it was the same comet returning, and Newton at first disagreed, but later changed his mind and never once mentioned the director's contribution. Even worse, Newton's good teammate Halley (yes, the same Halley of Halley's Comet) secretly gave Newton the star catalogue that the director had not yet published, and Newton used it right away. In 1712, when he became president of the Royal Society, he and Halley published the star catalogue together. The director was so angry that he paid out of his own pocket to buy back 400 copies and burned 300 of them on the spot. It wasn't until six years after his death that his widow had the authorized star catalogue printed.

(Sound effect: a tense standoff)

And then there was the "calculus war" with the German genius Leibniz. We now know that the two independently invented calculus (Newton used his "method of fluxions," while Leibniz used simpler notation). But at the time, to win the title of "inventor," Newton had the Royal Society anonymously publish a report saying Newton's method was superior. Later it was discovered that the "anonymous reviewer" was Newton himself! Leibniz was furious, the scientists of mainland Europe all sided with Leibniz, and British scholars stubbornly stuck to Newton's notation system. As a result, British mathematics fell behind the rest of the world by more than a hundred years, and the center of academic gravity slowly shifted to France.

(Sound effect: soothing music)

But let's not focus only on Newton's "dark history." His achievements before the age of 26 were epoch-making, whichever one you pick: calculus laid the foundations of modern mathematics, universal gravitation explained the laws of celestial motion, his optical theory let us see the nature of light, and reflecting telescopes are still used in observatories today... In 1696, a Swiss mathematician named Johann Bernoulli deliberately gave all of Europe's mathematicians a hard problem, the "brachistochrone problem," and secretly sent it to Newton hoping to humiliate him. Newton got home at four in the afternoon, saw the letter, stayed up all night, and sent the answer back by four in the morning, signed "an old Englishman" (Newton was 54 at the time). When Bernoulli received the answer, he was astonished: "From this claw, I recognize the lion!" (In other words: this style of solving the problem can only belong to Newton!)

(Sound effect: warm closing music)

So what was the real Newton like? He was a genius: before he turned 26 he already stood at the peak of science. He was also an ordinary human: he held grudges, he was jealous, he fell out with peers over reputation, and in his later years he was obsessed with alchemy (trying to turn base metals into gold) and lost his fortune in stock trading (it's said he lost so much he didn't even have underwear left). But it is exactly this "complexity" that makes him more real. Scientific progress has never come from "perfect saints." It has come from people who dare to think, dare to fight, and who are even a bit of a "troublemaker."

So the next time you hear the story of "Newton and the apple," you can smile and tell your friends: "Don't believe it. That might have been made up by his niece, or it might have been a bit Voltaire added." But don't forget that what truly made Newton great was not the apple, not Hooke, not any single argument. It was the 18 months he spent during the plague, and every page of formulas he wrote in that lonely attic, and his eternal questioning of "why" about this world.

(Music fades out)

Well, that's all for today's "Chronicles of Scientists." I'm your host, [Your Name], and I'll see you next time.
