He Solved a 358-Year-Old Problem. Alone. In His Attic. #history #shorts

[00:00:00]In 1637, a French mathematician named Pierre de Fermat scribbled a note in the margin of a book. He had discovered something extraordinary, he wrote. A proof so elegant it would change mathematics forever. But the margin, he added, was too narrow to contain it. Then he died.

[00:00:21]And for 358 years, every mathematician in the world tried to find that proof. The greatest mathematical minds of every generation attempted it. All failed. In 1986, a Princeton professor named Andrew Wiles decided to try, but told no one. For 7 years, he worked alone in his attic, building an entirely new [music] branch of mathematics to solve a problem no one had solved in 3 and 1/2 centuries.

[00:00:51]In 1993, he announced his proof to the world. The mathematical community celebrated.

[00:00:57]Then a colleague found a flaw. The proof was incomplete.

[00:01:02]Wiles spent another year working in secret.

[00:01:05]And then he found something in his own failed approach, a fragment of an earlier method that [music] combined with everything else completed the proof.

[00:01:15]He later said the moment he saw it, he stared at it for 20 minutes in disbelief.

[00:01:20]It was the most beautiful thing he had ever seen.

[00:01:24]The proof was complete.

[00:01:26]358 years after Fermat wrote his note, one man in an attic had finally mastered it.
