William Nicholson (13 December 1753 – 21 May 1815) was an English writer, translator, publisher, scientist, inventor, patent agent and civil engineer. He launched the first monthly scientific journal in Britain, Journal of Natural Philosophy, Chemistry, and the Arts, in 1797, and remained its editor until 1814.
The hygrometer, made of cardboard, shows a figure consisting of a friar of the Capuchin Order [3] with an open book in his right hand and the left arm and the hood of the habit mobile thanks to balanced axes; In this arm he carries a bar thanks to which he indicates the weather approximately 24 hours in advance on various signs arranged from top to bottom on a column while he moves his hood to ...
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.
[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 ...
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 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.
It was invented by Daniel Gabriel Fahrenheit (1686–1736), better known for his work in thermometry. The Nicholson hydrometer, after William Nicholson (1753-1815), is similar in design, but instead of a weighted bulb at the bottom there is a small container ("basket") into which a sample can be placed.
