Grigory Perelman, the Russian who seems to have solved one of the hardest problems in mathematics, has declined one of the discipline's top awards.
Trích dẫn:
At Leningrad University, which Perelman entered in 1982, at the age of sixteen, he took advanced classes in geometry and solved a problem posed by Yuri Burago, a mathematician at the Steklov Institute, who later became his Ph.D. adviser. There are a lot of students of high ability who speak before thinking, Burago said. Grisha was different. He thought deeply. His answers were always correct. He always checked very, very carefully. Burago added, He was not fast. Speed means nothing. Math doesnt depend on speed. It is about deep.
