Galois kept arguing with his professors, nobody would let him in to a top university. He got into a duel over a girl, knew he would lose, and stayed up all night writing his stuff, got killed and nobody could read his hand writing. 50 years later turns out he'd solved some major problems ( squaring the circle, trisecting the angle ). And when you connect today with cipher AES-GCM thats "Galois Counter Mode"
