Pascal's main contribution
1, physics
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 (syringe), 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.
2. Mathematics
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, "it is collinear with the intersection of three opposite sides of a conic inscribed in a hexagon".
