Pythagoras was a great mathematician. He studied numbers and organized the so-called Pythagorean Brotherhood. Pythagoras studied odd numbers, even numbers, prime numbers, composite numbers, affinity numbers and shape numbers. He proved the Pythagorean theorem (similar to China's Pythagorean theorem) and was very happy to kill 100 bulls to celebrate. So Pythagoras theorem is also called hundred cows theorem. But Pythagoras also failed. For example, his old man refused to admit the existence of irrational numbers, and all his students asked him what was the hypotenuse of a right triangle with a side length of 1? As a result, he scolded the students! !

Horizon: Fermat's Last Theorem

Lord Fermat himself has a nine-to-five job, but in his spare time, he likes to study mathematics. He likes doing math problems, especially writing the answer process in the blank of the book. After Fermat's death, people sorted out his math books and papers. As a result, I found a problem in a book: if the n power of x plus the n power of y equals the n power of z, and n is greater than 2, then x, y and z have no integer solutions. There is a sentence next to this question: "I have given a wonderful proof of this question, but the blank of this book is too small for me to write!" " "This sentence has puzzled later mathematicians for more than 350 years. (It is also an extremely complicated proof, which is not wonderful at all. )

It is said that a man once tried to commit suicide, and he arranged what to do for himself at the last minute. Among them, he arranged to go to the library to read books, accidentally turned to Fermat's last theorem, and began to study. When he woke up, the suicide time he had arranged for himself had passed, so he began a long mathematics study, but unfortunately, his compatriots could not solve the problem of proving Fermat's Last Theorem until his death.
