Galois1811was born in a small town in France on October 25th, and 1832 died in a duel with his rival in love on May 25th. He discovered a new mathematical theory in middle school, solved the problem of finding the roots of quintic equation that puzzled the mathematical community for hundreds of years, and was the first to put forward the concept of "group". The school contributed its own manuscript, but it lost twice. The most ridiculous thing is that it was "completely incomprehensible" when it was returned for the third time. He also participated in the French Revolution, but he died in a duel with his rival because of love and revolution. We can only know his charm from more than 60 pages of draft paper kept by his brother.
