Wellcome V0005861. Torricelli Invented the mercury barometer, recorded in the books of Camille Flammarion (1923) Torricelli's experiment was invented in Pisa in 1643 by the Italian scientist Evangelista Torricelli (1608-1647). The purpose of his experiment is to prove that the source of vacuum comes from atmospheric pressure.
Evangelista Torricelli (/ ˌtɒriˈtʃɛli / TORR-ee-CHEL-ee; [1][2] Italian: [evandʒeˈlista torriˈtʃɛlli] ⓘ; 15 October 1608 – 25 October 1647) was an Italian physicist and mathematician, and a student of Galileo. He is best known for his invention of the barometer, but is also known for his advances in optics and work on the method ...
An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, [23] the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule (or usually ...
1629 — Joseph Solomon Delmedigo describes in a book an accurate sealed-glass thermometer that uses brandy; 1638 — Robert Fludd the first thermoscope showing a scale and thus constituting a thermometer. 1643 — Evangelista Torricelli invents the mercury barometer
Meteorological instrumentation. Galileo thermometer. Meteorological instruments (or weather instruments), including meteorological sensors (weather sensors), are the equipment used to find the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does not ...
A barograph is a barometer that records the barometric pressure over time in graphical form. This instrument is also used to make a continuous recording of atmospheric pressure. The pressure-sensitive element, a partially evacuated metal cylinder, is linked to a pen arm in such a way that the vertical displacement of the pen is proportional to ...
t. e. Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century.
In the 18th century, the invention of the thermometer and barometer allowed for more accurate measurements of temperature and pressure, leading to a better understanding of atmospheric processes. This century also saw the birth of the first meteorological society, the Societas Meteorologica Palatina in 1780. [41]
