At age 19, Pascal invented the first calculating machine. At age 23, Pascal proved the existence of the [[vacuum]], which made possible barometers, hydraulic devices and hypodermic syringes.

Pascal is credited with developing the mathematical [[Probability|theory of probability]] (along with Fermat), and he discovered the significance of what is now known as [[Pascal's triangle]]. He also contributed to [[calculus]].

''Experimenting with the vacuum, Pascal published in 1663 his study TRAITÉ DE LA PESANTEUR DE LA MASSE DE L'AIR, where he argued that "experiments are the true teachers which one must follow in physics"... Pascal´s studies deeply influenced the development of modern essay writing. The idea of intuition as presented in Pensées had an impact on the philosophy of [[Jean-Jacques Rousseau]] (1712-1778), [[Edmund Husserl]] (1859-1938), and [[Henri Bergson]] (1859-1941) '' [http://kirjasto.sci.fi/bpascal.htm]
