Kelvin also wrote under the pseudonym "P. Q. R." William Thomson, 1st Baron Kelvin (26 June 1824 – 17 December 1907 [ 7 ]) was a British mathematician, mathematical physicist and engineer. [ 8 ][ 9 ] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research ...
The vortex theory of the atom was a 19th-century attempt by William Thomson (later Lord Kelvin) to explain why the atoms recently discovered by chemists came in only relatively few varieties but in very great numbers of each kind. Based on the idea of stable, knotted vortices in the ether or aether, it contributed an important mathematical legacy.
The 19th century British scientist Lord Kelvin first developed and proposed the scale. [ 5 ] It was often called the "absolute Celsius" scale in the early 20th century. [ 6 ] The kelvin was formally added to the International System of Units in 1954, defining 273.16 K to be the triple point of water. The Celsius, Fahrenheit, and Rankine scales ...
The Plum Pudding model was the first scientific model of the atom to describe an internal. structure. It was first proposed by J. J. Thomson in 1904 following his discovery of the electron in 1897, and was rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911. The model tried to account for two properties of atoms ...
Thomson's prize-winning master's work, Treatise on the motion of vortex rings, shows his early interest in atomic structure. [4] In it, Thomson mathematically described the motions of William Thomson's vortex theory of atoms. [18] Thomson published a number of papers addressing both mathematical and experimental issues of electromagnetism.
Kelvin water dropper. 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 ...
Kelvin equation. The Kelvin equation describes the change in vapour pressure due to a curved liquid–vapor interface, such as the surface of a droplet. The vapor pressure at a convex curved surface is higher than that at a flat surface. The Kelvin equation is dependent upon thermodynamic principles and does not allude to special properties of ...
The product of the mass of a body into the square of its velocity may properly be termed its energy. [4] Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term " potential energy." It was argued for some years whether energy was a substance (the caloric) or merely a physical ...
