Torricelli

Torricelli is an Italian surname. The most prominent bearer is Evangelista Torricelli (1608–1647), a physicist and mathematician whose work helped establish the study of atmospheric pressure. In 1643 he invented the mercury barometer, demonstrating that air pressure supports a column of mercury and that a space can exist above the liquid, which revealed that the atmosphere has measurable weight.

Torricelli's law states that the speed of efflux of a liquid through a small hole at the

In geometry, the Torricelli point, also called the Fermat point in some contexts, is the point inside

The name Torricelli is commemorated in lunar nomenclature as well, with a crater on the Moon named
