At 11, he was solving scientific mysteries. Built one of history's earliest calculators. But a gambling problem led him to crack the mathematics of chance
Blaise Pascal's early genius and invention of a mechanical calculator were overshadowed by his collaboration with Pierre de Fermat to solve the 'Problem of Points,' which laid the foundation for modern probability theory.Summary
Blaise Pascal was a prodigy who wrote about vibrating bodies at age 11 and developed a mechanical calculator, the Pascaline, before turning 19 to assist his father with tax calculations. His mathematical journey took a pivotal turn in 1654 when he began corresponding with Pierre de Fermat to solve the 'Problem of Points,' a gambling question about how to fairly divide stakes when a game ends early. Pascal introduced the concept of mathematical expectation and used recursive methods to calculate probabilities, while Fermat analyzed possible outcomes. This collaboration established the mathematical framework for probability theory, which later expanded into economics, actuarial science, and the social sciences. Pascal eventually abandoned mathematics after a religious experience following a carriage accident, but his work on a gambling puzzle had fundamentally changed how humanity understands uncertainty.
