Kelvin's clouds

Oliver Passon

Abstract

In 1900 Lord Kelvin identified two problems for 19th century physics, two "clouds" as he puts it: the relative motion of the ether with respect to massive objects, and Maxwell-Boltzmann's theorem on the equipartition of energy. These issues were eventually solved by the theory of special relativity and by quantum mechanics. In modern quotations, the content of Kelvin's lecture is almost always distorted and misrepresented. For example, it is commonly claimed that Kelvin was concerned about the UV-catastrophe of the Rayleigh-Jeans law, while his lecture actually makes no reference at all to blackbody radiation. I rectify these mistakes and explore reasons for their occurrence.

    • Poor Lord Kelvin gets maligned a lot: https://arxiv.org/abs/2106.16033 That aside, a distinction should be made between 1) claiming that physics is pretty much done (what he's often accused of) and 2) pointing out factual errors in claims about the current state of knowledge…

    • > but was it lord Kelvin who said, physics just needs to figure out the ultraviolet catastrophe and it's done? This is apparently a common misconception regarding a lecture given by Lord Kelvin in 1900 concerning "two clouds" in physics.[1] In fact, Max Planck solved the…
