The ultimate academic cliffhanger. Pierre de Fermat smugly announces his "marvelous proof" for what would become his famous Last Theorem—then promptly exits the mortal realm before sharing it. For the next 358 years, mathematicians collectively lost sleep trying to figure out what this mathematical tease had discovered. The margin was apparently large enough for his boast but mysteriously insufficient for the actual proof. Classic mathematician move: drop a revolutionary claim, refuse to elaborate, die.
