This man names the special case of the Archimedean spiral when n is set to two. Gauss showed that any number which can be expressed as a power of two times the product of numbers named for this man can be the number of sides in a constructible polygon. He is also the namesake of the statement that a to the p is equal to a modulo p if p is prime, and he proposed that light waves travel through the principle of least time. His most famous idea was proven by Andrew Wiles. For 10 points, name this namesake of a type of primes and a theorem that states that x^n plus y^n equals z^n has no solution for n greater than 2, his "last theorem."
