He also invented the dew-point hygrometer known by his name, [3] and a register pyrometer; [4] and in 1830 he erected in the hall of the Royal Society a water-barometer, with which he carried out a large number of observations. [5]
Although "the Weather friar" has been sometimes wrongly cited as the oldest hygrometer-meteorologist in the world, [1] [3] there is a similar hygrometer, with the shape of a Capuchin friar as well, from the late 18th century, in the Museum of Arts and Crafts in Paris, built by Charles Alexandre Clair and belonging to the physics office of Jacques Charles, who would bequeath his collection of ...
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
With the inventions of the hygrometer and thermometer, the theories of combining the two began to emerge during the sixteenth and seventeenth centuries. In 1818, a German inventor, Ernst Ferdinand August (1795-1870), patented the term “psychrometer”, from the Greek language meaning “cold measure”.
In 1820 Bellani invented a device for measuring evaporation that was called an atmometer. [3] Modified versions of the Bellani plate evaporimeter are still in use. [4] He invented a hygrometer using a fish bladder in 1836. Another innovation was his pyranometer to measure solar radiation which was a closed glass capsule in which alcohol was ...
In 1783, the first hair hygrometer is demonstrated by Horace-Bénédict de Saussure. In 1806, Francis Beaufort introduced his system for classifying wind speeds . [ 4 ] The April 1960 launch of the first successful weather satellite, TIROS-1 , marked the beginning of the age where weather information became available globally.
Claude Shannon (1916–2016), founder of information theory and modern cryptography, invented Minivac 601, and co-invented the first wearable computer (with Edward O. Thorp) Ugo Cerletti (1877–1963), together with Lucio Bini (1908–1964), Italy – Electroconvulsive therapy; Leona Chalmers (c. 1937), U.S. – modern menstrual cup
