  1. #MissKitty puts it as: Space does not move. Near the end, #Feynman references without naming the #Heisenberg principle which is how you measure or how you ask has an impact on result. #Relativity has that severe problem! Infinity solves all problems without an answer! 🎤🎤🎤💃💃💃😹😹😹 #Quantum #physics

  7. 3/n...limits on how fast and therefore how far we can get in a reasonable time. Most begin with Mass when they want to explain these constraints. Mass-Energy equivalence for the more technical dive.
    Meanwhile back at the ranch #Physics has a massless regime of particles and forces where coupling between mass and energy is not the pain in the ass it is elsewhere, so we have to talk about #QuantumMechanics.
    Funny thing that. It turns out that #Relativity and #QM don't get along...

  10. @setebos Small #note for #future #posts:

    Would be good to know why it's the #best #writing for you (before trying the link).

    It is a bit clearer and more chance if it's #relative to me, rather than "I'm not sure why".

    Just saying as I wouldn't usually want to click unless it's your stuff more directly and before trying other people's or without knowing why you recommend it.
    Thanks

  15. Now we get to Part Two, which is the commentary on "So what changes?"

    First, you can see that this is not simply galilean relativity, because you must calculate transformations of electromagnetic waveforms, or at least of parameters associated with them.

    But also this is not Special Relativity, because you are dealing with two ordinary cartesian coordinate systems...

    #physics #Relativity

  16. I am ready to describe a little how to replace Special Relativity with a better kinematics that discards the non-mathematical notions of ‘Observer’ and ‘Frame of Reference’. Instead one would use geometry both with and without coordinate systems, without the encumbrance of ‘physical’ interpretations.

    The full power of mathematics would be available.

    Without ‘Frames of Reference’, we should no longer call the kinematics ‘relativity’. Just ‘kinematics’.

    Let us proceed...

  17. The #paperOfTheDay is "Foundations of the new field theory" from 1934. This new field theory today goes by the name of "Born-Infeld theory", it is an alternative version of classical electrodynamics.
    Recall that in 1934, #quantum mechanics had recently been developed, but there was not yet any consistent #quantumFieldTheory , let alone a fundamental theory of elementary particles. In particular, classical (Maxwell) electrodynamics predicts an infinite self-energy if one assumes the electron to be point-like, and people discussed different ways to unify the picture of microscopic #physics .
    Born-Infeld theory represents one possible scenario, modeled after Einstein's general theory of #relativity . Namely, a theory of electromagnetism based on general coordinate invariance, and the assumption that there is an universal maximum electrical field strength that no system can exceed. This gives rise to a Lagrangian that is structurally similar to the Einstein-Hilbert one. The field equations are then non-linear, but reduce to the Maxwell theory for weak enough fields in flat space.
    Close to the center of an electron, the field strength is large, and the new theory is substantially different from classical electrodynamics: The potential is not singular at the origin, but always stays finite.

    Later, however, many of the old mysteries got resolved with the quantization of Maxwell electrodynamics. On the other hand, Born-Infeld theory (much like general relativity) is strongly non-linear and hard to quantize with existing methods.

  32. 🧵 Eddington's observations famously confirmed Einstein's prediction of the gravitational deflection of starlight passing near the sun.

    This was a major step in the acceptance of General Relativity (GR).

    So it might surprise some to hear that Newton had thought about this a lot earlier! 1/9
