Lord Kelvin. It is believed the "PNP" in his signature stands for "Professor of Natural Philosophy". Kelvin also wrote under the pseudonym "P. Q. R." William Thomson, 1st Baron Kelvin was a British mathematician, mathematical physicist and engineer. [7][8] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow ...
The heat death paradox, also known as thermodynamic paradox, Clausius' paradox, and Kelvin's paradox, [ 1] is a reductio ad absurdum argument that uses thermodynamics to show the impossibility of an infinitely old universe. It was formulated in February 1862 by Lord Kelvin and expanded upon by Hermann von Helmholtz and William John Macquorn ...
The second law of thermodynamics may be expressed in many specific ways, [25] the most prominent classical statements [26] being the statement by Rudolf Clausius (1854), the statement by Lord Kelvin (1851), and the statement in axiomatic thermodynamics by Constantin Carathéodory (1909). These statements cast the law in general physical terms ...
Notable critics included Simon Newcomb, Lord Kelvin, and the chief engineer of the US Navy, George W. Melville, the latter of whom described flying machines as "wholly unwarranted, if not absurd". [4] After five years of preparations, aviation pioneer Samuel Langley was ready to test out his Aerodrome on October 7, 1903.
Lord Kelvin originated the idea of universal heat death in 1852. In 1852, Thomson published On a Universal Tendency in Nature to the Dissipation of Mechanical Energy , in which he outlined the rudiments of the second law of thermodynamics summarized by the view that mechanical motion and the energy used to create that motion will naturally tend ...
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.

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. Hence the Treatise on Natural Philosophy came to be commonly referred to as.
