  • "An Elementary Fact Worth Remembering" - Discussion

    • Martin
    • January 26, 2025 at 5:51 AM
    Quote

    The idea that light is massless will be thrown away eventually along with the rest of Einstein's magic tricks.


    According to the model which is the most consistent with observations, light has mass while the elementary particle which makes up light, the photon, has a nominal rest mass of zero. While we can carry out experiments in which it appears that light is slowed down or photons are trapped, a single photon cannot actually be at rest. In every frame of reference except for its own, it moves with the speed of light throughout its existence.

    It might happen that in future, a photon rest mass of more than zero is discovered. The current model can accommodate this by separating the speed of light from the maximum speed of information transport, which would then be slightly higher than the speed of light, and which would then be used instead of the speed of light in the Lorentz transforms and some other formulas. However, a photon rest mass of more than zero would certainly motivate the search for a superior model.

    Although from a theoretical perspective, Einstein's theories and quantum mechanics have replaced Newton's theory of gravity/mechanics, in actual practice, Newton's theory is still far more often applied than the newer theories because Newton's mechanics is accurate enough and more efficient to use for problems which are within its limits. Therefore, Newton's mechanics has never been thrown away. Similarly, it appears unlikely, that Einstein's "magic tricks" will be thrown away, because they do work well. We just do not know whether they have a range beyond which they become inadequate.

    The chatbot does not think. Probably, it uses "oversimplified" because it has more detailed texts on the topic in the training data.

    This may be a related snippet of the "story" (but tentatively, the timing does not match):

    Quote

    a certain Theotimus, convinced that he had composed infamous letters, addressed to some of the women who frequented his gardens, was condemned to lose his life.

    from Charles' thread on the article on Epicureanism in Diderot's encyclopedia:

    Post

    (Diderot) Denis - "Epicureism, or Epicurism", Vol. 5 of The Encyclopedia

    EPICUREISM or EPICURISM, noun. m. ( History of Philosophy .) The Elean sect gave birth to the Epicurean sect . Never has philosophy been less heard and more slandered than that of Epicurus . This philosopher was accused of atheism, although he admitted the existence of the gods, that he frequented the temples, and that he had no reluctance to prostrate himself to the feet of the altars. He was regarded as the apologist for debauchery, he whose life was a continual practice of all the virtues,…
    Charles
    April 13, 2020 at 8:55 PM

    I recall another snippet indicating that someone (probably Theotimus) was sentenced to death because he was found guilty of slander. However, the search did not reveal that other snippet on epicureanfriends.com.
