What did Pascal achieve?

Pascal's achievement is to find that atmospheric pressure changes with height.

Pascal put forward the law that fluid can transfer pressure in 1653, which is called Pascal's law. Using this principle, a hydraulic press is manufactured. He also made a water injector, inherited the atmospheric pressure experiment of Galileo and E Torricelli, and found that the atmospheric pressure changed with height. Pascal, the pressure unit in the international system of units, is named after his surname.

Story:

Pascal has a deep knowledge of mathematics. In addition to his outstanding contribution to probability theory, the most prominent one is Pascal's theorem put forward in his paper on conic curves. Pascal's theorem is an important theorem in projective geometry, that is, "a conic curve inscribed with the intersection of three opposite sides of a hexagon".

In the study of algebra, he published many papers about arithmetic progression and binomial coefficients, and discovered the coefficient law of binomial expansion, the famous Pascal triangle.

Together with Fermat, he laid the foundation of probability theory and combinatorial theory and obtained a series of methods to solve the problems of probability theory. He studied the cycloid problem and obtained the general solutions of different curve areas and centers of gravity. He calculated the integrals of trigonometric functions and tangents, and introduced elliptic integrals for the first time.
