The Enigma of Fermat's Last Theorem
Fermat's Last Theorem was conjectured by Pierre de Fermat in 1637. It states that no three positive integers a, b, and c satisfy the equation an + bn = cn for any integer value of n greater than 2.
The theorem was famously proven by Andrew Wiles in 1994, using sophisticated techniques from modern mathematics. You can learn more about his work here!
