2. Fahrenheit - Wikipedia

   en.wikipedia.org/wiki/Fahrenheit

   x + 459.67 °Ra. The Fahrenheit scale (/ ˈfærənhaɪt, ˈfɑːr -/) is a temperature scale based on one proposed in 1724 by the European physicist Daniel Gabriel Fahrenheit (1686–1736). [1] It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests ...

   en.wikipedia.org/wiki/Daniel_Gabriel_Fahrenheit

   Daniel Gabriel Fahrenheit FRS (/ ˈfærənhaɪt /; German: [ˈfaːʁn̩haɪt]; 24 May 1686 – 16 September 1736) [ 1 ] was a physicist, inventor, and scientific instrument maker, born in Poland to a family of German extraction. Fahrenheit invented thermometers accurate and consistent enough to allow the comparison of temperature measurements ...

   1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the scale so the melting point of ice was 32 and the upper point 96, meaning that the difference of 64 could be got by dividing the ...

5. Temperature - Wikipedia

   en.wikipedia.org/wiki/Temperature

   As a collection of classical material particles, the temperature is a measure of the mean energy of motion, called translational kinetic energy, of the particles, whether in solids, liquids, gases, or plasmas. The kinetic energy, a concept of classical mechanics, is half the mass of a particle times its speed squared.

   1886: Charles Martin Hall and independently Paul Héroult invent the Hall–Héroult process for economically producing aluminum in 1886. 1886: Karl Benz invents the first petrol or gasoline powered auto-mobile (car). [ 440 ] 1887: Carl Josef Bayer invents the Bayer process for the production of alumina.

7. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer is a device that measures temperature (the degree of hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in ...

   Fahrenheit (°F) Rankine (°R or °Ra), which uses the Fahrenheit scale, adjusted so that 0 degrees Rankine is equal to absolute zero. Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature measurement in the ...
