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.
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 ...
Treatise on Natural Philosophy was an 1867 text book by William Thomson (later Lord Kelvin) and Peter Guthrie Tait, published by Oxford University Press. The Treatise was often referred to as T {\displaystyle T} and T 1 {\displaystyle T^{1}} , as explained by Alexander Macfarlane : [ 1 ] : 43
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). [13]
An entirely new system, providing continuous automatic recording, was installed by Lord Kelvin personally in the early 1860s. This device, based on Kelvin's water dropper potential equaliser with photographic recording, [17] was known as the Kew electrograph. It provided the backbone of a long and almost continuous series of potential gradient ...

In 1876, Lord Rayleigh published his mathematical theory to support Russell's experimental observation. At the end of his paper, [ 1 ] Rayleigh admitted that Boussinesq's theory came before his. In 1897, he published Théorie de l'écoulement tourbillonnant et tumultueux des liquides ("Theory of the swirling and agitated flow of liquids"), a ...
