Absolute temperatures are stated in units of kelvin in Lord Kelvin's honour. While the existence of a coldest possible temperature, absolute zero , was known before his work, Kelvin determined its correct value as approximately −273.15 degrees Celsius or −459.67 degrees Fahrenheit . [ 13 ]
The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
One of the earliest practical uses of Thomson's concepts was a tide-predicting machine built by Kelvin starting in 1872–3. On Lord Kelvin's advice, Thomson's integrating machine was later incorporated into a fire-control system for naval gunnery being developed by Arthur Pollen, resulting in an electrically driven, mechanical analogue ...
He was born in Edinburgh on 24 October 1868, the eldest son of Alexander Erskine Erskine-Murray , Sheriff of Glasgow (1832-1907), and his wife, Helen Pringle, [1] daughter of Robert Pringle of Symington. [2] In 1886 he began study under Lord Kelvin at Glasgow University assisting Kelvin in electrical experiments from 1888 and graduating BSc in ...
His proposers were Lord Kelvin, James Thomson Bottomley, and John Gray McKendrick. He served as vice-president to the society 1906 to 1909. [2] In June 1896 he was elected a Fellow of the Royal Society [3] He remained in Bangor until 1899, when he returned to Glasgow to become the Professor of Natural Philosophy, succeeding Kelvin on his ...
It had been long known that continuous electric currents flowed through the solid and liquid portions of the Earth, [5] and the collection of current from an electrically conductive medium in the absence of electrochemical changes (and in the absence of a thermoelectric junction) was established by Lord Kelvin. [6] [7] Lord Kelvin's "sea ...

The first tide predicting machine (TPM) was built in 1872 by the Légé Engineering Company. [11] A model of it was exhibited at the British Association meeting in 1873 [12] (for computing 8 tidal components), followed in 1875-76 by a machine on a slightly larger scale (for computing 10 tidal components), was designed by Sir William Thomson (who later became Lord Kelvin).
