In 1643, Evangelista Torricelli invented the first barometer. He figured that if he had a vacuum, an airless space, he could compare the ever-present atmospheric pressure with zero. Torricelli placed a vacuum contained in a glass tube on top of a larger container of mercury. The air pressed ...
The pressure is shown on your barometer’s dial, usually expressed in “inches” referring to “inches of mercury” (inch Hg). The early barometers measured the pressure by the rise or fall of a column of mercury. This mercury barometer was invented back in 1643 by a pupil of Galileo nam...
Within this frame, Torricelli's mercury esperienza as he called it heralds the birth of modern experimental science through his invention of the first modern barometer. This paper questions this traditional narrative by re-interpreting the archival foundations upon which this account is based. In ...

Torricelli attracted considerable attention when he demonstrated the first mercury barometer to the general public. He is credited with giving the first modern explanation of atmospheric pressure. Scientists at the time were familiar with small fluctuations in height that occurred in barometers. When thes...
What is Mercury retrograde and why does it have such a bad reputation? As Mercury is closer to the Sun than the Earth is, it often appears to be moving backwards from the perspective of a viewer on Earth. Back when it was believed that the stars were all equidistant from the earth, em...
In the case of a mercury barometer, the density difference between the mercury in the tube and the density of the surrounding air is enormous. But, the weight of the atmosphere is high enough to support the column of mercury. In the case of a salt dome, thousands of feet of sediment, ...
