Citáty Lord Kelvin
„Létací prostředky těžší než vzduch jsou čirým nesmyslem.“
prezident Royal Society, 1895

Lecture on "Electrical Units of Measurement" (3 May 1883), published in Popular Lectures Vol. I, p. 73, as quoted in The Life of Lord Kelvin (1910) by Silvanus Phillips Thompson
„I have not the smallest molecule of faith in aerial navigation other than ballooning“
As a response to Major B. F. S. Baden Powell's request to join the Aeronautical Society, December 8, 1896 http://zapatopi.net/kelvin/papers/letters.html#baden-powell.
Often reproduced out of context and without citation to any primary source as "Heavier-than-air flying machines are impossible", like in The Experts Speak : The Definitive Compendium of Authoritative Misinformation (1984) by Christopher Cerf and Victor Navasky, p. 236
Kontext: 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.
From a 1900, April 27, , Sixth Series, 2, 1–40 (1901).
Thermodynamics quotes
Kontext: 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.

„Tesla has contributed more to electrical science than any man up to his time.“

Thermodynamics quotes
Quoted in Life of Lord Kelvin (1910) by Silvanus Phillips Thompson
Misattributed to Kelvin since the 1980s, either without citation or stating that it was made in an address to the British Association for the Advancement of Science in 1900. There is no evidence that Kelvin said this, 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." The attribution to Kelvin giving an address in 1900 is presumably a confusion with his “Two clouds” speech, delivered to the Royal Society in 1900 (see above), and which on the contrary pointed out areas that would subsequently see revolutions.
