Homage to Pierre de Fermat’s old problem, which stated that xn + yn = zn has no solutions for positive integers x, y, and z, if n is greater than 2. This became known as Fermat’s Last Theorem.
There are many solutions for n = 2, such as when x = 3, y = 4, and z = 5. Fermat said he had a proof that n could not be larger than 2, but neglected to write it down.
For 350 years no one could prove whether it was true or not. Finally in 1993, Andrew Wiles (with help from Richard Taylor) solved the problem. Fermat was right.
