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 and , as explained by Alexander Macfarlane: [1]: 43
Lord Kelvin was commemorated on the £20 note issued by the Clydesdale Bank in 1971; in the current issue of banknotes, his image appears on the bank's £100 note. He is shown holding his adjustable compass and in the background is a map of the transatlantic cable.
Between 1870 and 1890 the vortex atom theory, which hypothesised that an atom was a vortex in the aether, was popular among British physicists and mathematicians. William Thomson, who became better known as Lord Kelvin, first conjectured that atoms might be vortices in the aether that pervades space.
It was proposed by the physicist James Clerk Maxwell in 1867. [1] In his first letter, Maxwell referred to the entity as a "finite being" or a "being who can play a game of skill with the molecules". Lord Kelvin would later call it a "demon". [2] In the thought experiment, a demon controls a door between two chambers containing gas.
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.
Peter Guthrie Tait FRSE (28 April 1831 – 4 July 1901) was a Scottish mathematical physicist and early pioneer in thermodynamics.He is best known for the mathematical physics textbook Treatise on Natural Philosophy, which he co-wrote with Lord Kelvin, and his early investigations into knot theory.
Trivial knots, or unknots. Knots have been used for basic purposes such as recording information, fastening and tying objects together, for thousands of years.The early significant stimulus in knot theory would arrive later with Sir William Thomson (Lord Kelvin) and his vortex theory of the atom.
1865 – Lord Kelvin introduces the Kelvin material model for viscoelasticity. [33] 1867 – Helmholtz works on Helmholtz's theorems for vortex dynamics. 1867 – James Clerk Maxwell introduces the Maxwell material model for viscoelasticity. 1868–1871 – Helmholtz and Kelvin study and develop the theory of the Kelvin–Helmholtz instability ...
