[1] [failed verification] 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 ...
Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction
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 ...
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
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.
He published on his personal domain, "Fourmi Lab", designed to be a play on Fermilab and Fourmi, French for “ant”, one of his early interests. [15] On his Web site, Walker published about his personal projects, including a hardware random number generator called HotBits, along with software that he wrote and freely distributed, such as his Earth and Moon viewer.
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.
A thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point).Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.
