Torricelli (Evangelista Torricelli)

Evangelista Torricelli was an Italian physicist and mathematician, best known for inventing the barometer in the 17th century. He discovered that atmospheric pressure could support a column of mercury in a tube, which led to measuring air pressure and understanding weather patterns. This work contributed significantly to the study of fluid dynamics and the principles of vacuum. Torricelli also made contributions to mathematics, particularly in calculus, and is remembered for Torricelli's law, which describes the speed of fluid flowing out of an opening. His innovations laid important groundwork for modern physics and engineering.
