Blaise Pascal was born in Clermont-Ferrand (Auvergne - central France) on June 19, 1623. As a brilliant man, Blaise Pascal made important contributions to science, mathematics, and religious philosophy.

In *science* Pascal studied mainly hydrodynamics, and hydrostatic and
atmospheric pressure. This led him to the invention of the syringe and the hydraulic press.
He established the principle of hydrostatics now known as Pascal's law.

In *mathematics* he made a pioneering work in projective geometry, calculus
and probability theory. Also his independent discovery of the arithmetical triangle called
now "Pascal triangle" is famous.
In 1642 he invented the mechanical adding machine called **Pascaline**.

Pascal died of stomach cancer at the age of 39 (Aug. 19, 1662).
