Blaise Pascault (1623.6.19¨C1662.8.19) was a famous French mathematician, physicist, philosopher and poet. His outstanding contribution to physics was the first introduction of the famous Pascault Law in 1653, for which he wrote the famous paper The Discourse of Liquid Balance, which detailed the problem of the transmission of fluid pressure. The various hydraulic mechanisms made by applying this law have created countless wonders for mankind, and the principles of intuition he established have later influenced some philosophers, such as Rousseau and Bergson.

Clemont-Ferrand, born on 19 June 1623 in the province of Oviedo, France, did not receive formal school education. At the age of four, his mother fell ill, he was educated and nurtured by his father, an educated, government official, and two sisters. His father was a respected mathematician, and under his careful education, Pascal moved to Paris in 1631 with his family. His father found Pascal very familiar with Eurydice geometry, and at the age of sixteen he independently discovered the first 32 theorems of Eurydice, and the order was also completely correct. At the age of twelve, after discovering ¡°the inner corner of the triangle and equal to 180 degrees¡± alone, the teacher began to study mathematics from his father. In 1631 Pascal moved home to Paris. His father

In 1641 Pascal moved home to Rouen. When he helped his father do the tax calculation work between 1642 and 1644, he invented the additive, the world's earliest calculator, which is now displayed in the French museum. Between 1653 he concentrated on the study of vacuum and fluid statics and achieved a series of major achievements. Between 1647 and 1648, he published papers on vacuum problems. His research and writings on vacuum problems further enhanced his reputation. In 1648, Pascal conceived and conducted experiments on different heights of intensive measurement of atmospheric pressure in the same region, discovering the laws of strong increase of atmospheric pressure with decreasing heights. During these years, Pascal continuously made new discoveries in the experiment, and several major inventions, such

Pasca died on August 19, 1662, at the age of 39. The latter, in honor of Pasca's contribution, named the unit of force by his name, abbreviated Pa, symbolized by Pa.
