description Pierre de Fermat Overview
Pierre de Fermat was a 17th-century French lawyer and mathematician whose work profoundly shaped number theory. He developed deductive methods within mathematics and explored concepts like prime numbers and perfect numbers. His significant contributions influenced generations of mathematicians. Fermat’s enduring legacy rests on his numerous conjectures, notably the Last Theorem, which remained unresolved for centuries and continues to challenge researchers today.
He is primarily studied by students and scholars of mathematical history and number theory.
help Pierre de Fermat FAQ
What is Pierre de Fermat most famous for?
Fermat is most famous for Fermat's Last Theorem, the claim that no positive integers solve `a^n + b^n = c^n` for integers `n` greater than 2. Andrew Wiles finally proved the theorem in the 1990s.
Was Pierre de Fermat a professional mathematician?
No, Fermat was a French lawyer and magistrate who did mathematics privately. Despite that, his work strongly shaped number theory, analytic geometry, probability, and calculus.
What is Fermat's little theorem used for?
Fermat's little theorem is a basic result in modular arithmetic involving prime numbers. It appears in number theory and in modern cryptographic ideas that depend on arithmetic modulo primes.
Did Fermat work with Pascal on probability?
Yes, Fermat corresponded with Blaise Pascal about gambling problems in the 1650s. Their exchange is often treated as one of the starting points of mathematical probability theory.
