Meet Isaac Newton (1643–1727): a sickly, premature baby that nobody expected to survive, who grew up to become possibly the most famous scientist who has ever lived. Not a bad glow-up.
Yes, there was an apple. No, it (probably) did not bonk him on the head — that part got added later to make the story better. But watching an apple fall really did set him wondering: why does the apple drop, while the Moon stays up? His brain-melting answer: the Moon is falling — it's just moving sideways so fast that it keeps missing the Earth. That single idea, gravity, holds the whole Solar System together.
To do his physics, Newton needed a new kind of maths for things that change — so he just… invented calculus. Then he sat on it for nearly twenty years without properly publishing it, because he hated criticism and couldn't be bothered with the drama.
Which was awkward, because over in Germany a man named
When he wasn't reinventing the universe, Newton was a secret alchemist, trying to turn ordinary metal into gold and hunting for a magic "philosopher's stone." He actually wrote more about alchemy and religion than about physics.
Later he ran the Royal Mint and became a real-life crime-fighter, personally tracking down coin-forgers and sending them to the gallows. He also once slid a blunt needle behind his own eyeball just to see what would happen to his vision. Genius, yes. Role model for eye safety, absolutely not.
His famous law of motion still fits on a sticky note — force equals mass times acceleration:
