What mathematical event occurred in 1640?

Answer 1

In 1640, the mathematician Pierre de Fermat famously stated his Last Theorem, which posited that there are no three positive integers (a), (b), and (c) that satisfy the equation (a^n + b^n = c^n) for any integer value of (n) greater than 2. He wrote this assertion in the margin of his copy of an ancient Greek text, claiming to have a proof that was too large to fit in the margin. This conjecture remained unproven for over 350 years until it was finally proven by Andrew Wiles in 1994. Fermat's Last Theorem has since become one of the most famous problems in mathematics.
