Blaise Pascal (1623-1662) contributed to the development of hydraulics, the calculus, and the mathematical theory of probability.

Short Biography:

In mathematics, Pascal is known for his work on conic sections and, with Pierre de Fermat, the probability theory. He discussed Pascal's triangle, a triangular array of numbers in which each number is the sum of the pair of numbers above it.

In physics, Pascal's chief work concerned fluid pressure and hydraulics. Pascal's principle states that the pressure everywhere in a fluid is the same, so that pressure applied at one point is transmitted equally to all parts of the container. This is the principle of the hydraulic press and jack.

In 1654, he went into the Jansenist monastery of Port Royal and defended a prominent Jansenist against the Jesuits in his Lettres Provinciates in 1656. His Pensees in 1670 was part of an unfinished defence of the Christian religion.
