    Can't use links to Twitter (which is now X)

    When I copy a link from twitter and paste it into the insert media panel, I get this: when using this as a link: https://x.com/Rainmaker1973/status/1701523035621077394?s=20 I am guessing its because Twitter is making a bunch of dumb-ass changes and PF has not caught up, but maybe someone...

    I Links between the Lorentz equations and SR/GR

    I have a question linked to the equations of Lorentz: The Theory of the Special Relativity (SR) of Albert Einstein comes from the equation of Lorentz and we have the following equation on the time t’ in the moving frame: The space time (x’, y’, z’, t’) is moving at a speed v measured from the...

    Interesting Links Between Faraday's EM Induction and EPR

    Imagine a magnet moving up and down so that its flux 'B' cuts the copper rod to produce an alternating emf, suppose if the movement is fast enough such that its frequency equals to the electron spin resonance frequency given by F = B x 2.8 Mhz per gauss, neglecting skin effect, more copper...

    A Exploring Enrico Fermi's Beta-Decay Theory: A Search for Missing Links

    In 1933 Enrico Fermi published a paper on his theory of beta-decay. He describes it as a contact force, which means he didn't think there was a mediator as there was for the electrodynamic forces. Somewhere along the line, there must have been someone who suggested a mediating particle such as...

    B A couple of links about, not from science

    We repeatedly receive some fundamental questions, some of them of philosophical nature, which we're not very keen to answer - not because they weren't legitimate questions, but because we made the experience, that they simply lead nowhere, and, I'll have to admit, because of the lack of...

    I Size of links and loads in the hydraulic system

    I am currently in the process of creating my own design in which every millimeter counts. I have the following question: does the cross-section area of the highlighted link make a difference, and does decreasing the area makes force exerted on the walls greater? My guess is that cross-section...

    Visual Aids & Videos to Help You Learn Physics - Sanctioned by Physics Forums

    To some degree I can cope with Jargon and formulas, but they often slow me down to the point where I stall. I learn best with either visual aids or analogies that I can picture. And that's why I find videos so helpful. For example, I loved Carl Sagan's Cosmos series. His cosmic calendar is such...
