Blaise Pascal

Definition

Blaise Pascal was a French mathematician, physicist, and inventor, known for his significant contributions to the fields of fluid mechanics and probability theory. His work laid the foundation for Pascal's principle, which describes how pressure applied to a confined fluid is transmitted undiminished throughout the fluid. Pascal's innovative ideas extend beyond mechanics, influencing philosophy and theology as well.
