While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem standing for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra, and the subfield of Galois connections. He died at age 20 from wounds suffered in a duel.Created by: Ninjaivery hard 30% Évariste GaloisÉvariste Galois411Stefan BanachStefan Banach426David HilbertDavid Hilbert301Bertrand RussellBertrand Russell223mathematics riddles » Which Greek inventor is called the "father of pneumatics"?Ctesibius or Ktesibios or Tesibius was a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt. He wrote the first treatises on the science of compressed air and its uses in pumps (and even cannons).
