Otros nombres:Lord William Thomson Kelvin,William Kelvin,William Thomson, 1. Baron Kelvin
William Thomson, primer barón Kelvin, OM, GCVO, PC, FRS fue un físico y matemático británico.
Kelvin destacó por sus importantes trabajos en el campo de la termodinámica y la electricidad, gracias a sus profundos conocimientos de análisis matemático. Es uno de los científicos que más contribuyó a modernizar la física. Es especialmente conocido por haber desarrollado la escala de temperatura Kelvin. Recibió el título de barón Kelvin en honor a los logros alcanzados a lo largo de su carrera.
Siempre activo en las investigaciones industriales y de desarrollo, en 1899 aceptó la invitación de George Eastman para ser vicepresidente de la junta directiva de la empresa británica Kodak Ltd., filial de Eastman Kodak.

„The beauty and clearness of the dynamical theory, which asserts heat and light to be modes of motion, is at present obscured by two clouds.“
— William Thomson
Context: The beauty and clearness of the dynamical theory, which asserts heat and light to be modes of motion, is at present obscured by two clouds. I. The first came into existence with the undulatory theory of light, and was dealt with by Fresnel and Dr. Thomas Young; it involved the question, how could the earth move through an elastic solid, such as essentially is the luminiferous ether? II. The second is the Maxwell–Boltzmann doctrine regarding the partition of energy.

„I have not the smallest molecule of faith in aerial navigation other than ballooning“
— William Thomson
Context: I am afraid I am not in the flight for “aerial navigation”. I was greatly interested in your work with kites; but I have not the smallest molecule of faith in aerial navigation other than ballooning or of expectation of good results from any of the trials we hear of. So you will understand that I would not care to be a member of the aëronautical Society.

Misattributed to Kelvin since the 1980s, either without citation or stating that it was made in an address to the in 1900. and the quote is instead a paraphrase of Albert A. Michelson, who in 1894 stated: "… it seems probable that most of the grand underlying principles have been firmly established … An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals."

„Symmetrical equations are good in their place, but 'vector' is a useless survival, or offshoot from quaternions, and has never been of the slightest use to any creature.“

„Quaternions came from Hamilton after his really good work had been done, and though beautifully ingenious, have been an unmixed evil to those who have touched them in any way.“

Letter to Robert Baldwin Hayward (1892), as quoted in Energy and Empire : A Biographical Study of Lord Kelvin (1989) by Crosbie Smith and M. Norton Wise
„1. There is at present in the material world a universal tendency to the dissipation of mechanical energy.
2. Any restoration of mechanical energy, without more than an equivalent of dissipation, is impossible in inanimate material processes, and is probably never effected by means of organized matter, either endowed with vegetable life or subjected to the will of an animated creature.
3. Within a finite period of time past, the earth must have been, and within a finite period of time to come the earth must again be, unfit for the habitation of man as at present constituted, unless operations have been, or are to be performed, which are impossible under the laws to which the known operations going on at present in the material world are subject.“

„If the water flow down by a gradual natural channel, its potential energy is gradually converted into heat by fluid friction, according to an admirable discovery made by Mr Joule of Manchester above twelve years ago, which has led to the greatest reform that physical science has experienced since the days of Newton. From that discovery, it may be concluded with certainty that heat is not matter, but some kind of motion among the particles of matter; a conclusion established, it is true, by Sir Humphrey Davy and Count Rumford at the end of last century, but ignored by even the highest scientific men during a period of more than forty years.“
