Biography[]
Blaise Pascal was born in Clermont-Ferrand, France on 19 June 1623, and he was educated by his father, a tax collector in Rouen. Pascal's early studies included fluids, pressure, and vacuum, and he built 20 "Pascaline calculators", the first mechanical calculator. Pascal also accidentally invented the roulette machine with his "perpetual motion machine", and he also developed the probability theory. His inventions and discoveries helped to develop the future of geometry, physics, and computer science, and Pascal would later become a theologian, supporting the Jansenism school of Catholicism. Pascal notably created "Pascal's Wager", which stated that, through calculation of risks and benefits, it is better to believe in God, as, if He does exist, humans will be rewarded for their faith, while they will suffer if they do not, and that, if He does not exist, humans can only stand to gain from believing in Him while losing nothing by not believing. Pascal died in 1662 at the age of 39 from a stomach tumor and tuberculosis.
