• The problem with structure of Electric-Field

    From israel sadovnik@21:1/5 to All on Fri Aug 4 04:48:29 2023
    The problem with structure of Electric-Field
    ----.
    Maxwell's classical electrodynamics is determined and obeys Galilean transformations.
    But the further development of Maxwell's theory led to strange facts:
    1 - Maxwell's continuous field became discrete
    2 - laws have become probabilistic
    3 - the theory took on a dualistic form
    4 - the theory became subject to Lorentz transformations
    The strange facts were called "Quantum theory"
    -------.
    In contrast to classical electrodynamics, in quantum physics there is a gap between
    the field and the particle: in one experemeht the quantum particle behaves as a corpuscular,
    in other - like a wave. From a theoretical point of view, this gap seems impossible,
    because these pairs complement each other and do not allow one-sided elimination
    without violating the situation in the whole quantum theory.
    The problem is: to explain "duality" of quantum particles, to connect two discrete parts
    (wave and corpuscular), and this problem has not been solved for more than 100 years.
    A simple question: does a wave create particles, or does a quantum particle create waves?
    If a quantum particle creates waves, how does it create them?

    That is not the case. Maxwellian electrodynamics predicts that light
    travels at a constant speed in vacuo. That is inconsistent with the
    Galilean transformations.

    It is this contraction between classical mechanics (Galilean-invariant)
    and classical electrodynamics (Lorentz-invariant) that led to the
    development of Special Relativity.

    You mean contradiction. Contraction plays a role, of course, in the theory.

    I'm puzzled: why did it take so long for this development?
    Didn't anyone draw the rather clear conclusions from it before Einstein? Einstein's own book on relativity is easy for anyone with a year or two
    of college physics to follow, and IIRC it shows how Fitzgerald-Lorenz contraction,
    time dilation, etc follow from the invariant velocity, c, of light.

    I thought quantum mechanics solved it. In Hegelian terms, it supposedly is the higher synthesis
    between thesis (wave theory) and antithesis (corpuscular theory). Is this incorrect?

    If a quantum particle creates waves, how does it create them? -----------…

    What I find really mind-boggling is that fields for different particles permeate all of the
    universe, and with the right amount of stimulation, produce particles of the same name.

    A comparatively recent case: the tremendous localized energies to produce a Higgs boson
    from the ubiquitous Higgs field. It has to be ubiquitous, because without it, the masses
    of all particles, including the Higgs boson, would be radically different or nonexistent.

    The localized energy Is much less for the electron, but here is another puzzle: I keep reading that the "spontaneous" production of the electron is accompanied by the simultaneous creation of a positron, its antiparticle. Did the production
    of the Higgs boson also produce its anti-particle? I couldn't find this information
    in Wikipedia, or even the name of the anti-particle.

    I'm surprised that you're puzzled; as a working mathematician you should
    have a keen understanding of the difference between creating new
    theorems and understanding settled theorems. (Newton and Leibnitz are
    accounted geniuses for their invention of calculus, but it taught in
    high school. So, far that matter, is Special Relativity, in some
    schools, though I was introduced to it in freshman physics.)

    I don't recall the history in detail, if I ever knew it, but my
    recollection tells me that among the early attempts at reconciling the
    two theories was an interpretation that Maxwell's equations applied in a preferred (absolute) reference frame. Einstein is reported to have said
    that he was unaware of the Michelson-Morley experiment when he derived
    Special Relativity, but prior to that there may not have been any
    observations that falsified that interpretation. In another forum it was recently commented that Einstein's particular genius was to take another physicist's ad-hoc hypothesis, take it seriously, and explore the
    implications - another example given was taking Planck's postulate of
    the quantisation of light to solve the problem of the ultraviolet
    catastrophe, and applying it to the problem of the photoelectric effect
    (which is what Einstein got the Nobel Prize for). Further examples given
    were Brownian Motion (taking the existence of atoms and molecules
    seriously) and Bose-Einstein condensation.

    Part of the delay seems to be due to the assumption that a material
    medium (the ether) was required for the propagation of electromagnetic radiation, resulting in physicists trying to resolve the contradiction
    using properties of the ether. Einstein cut the Gordian Knot. (It is
    widely believed that if Einstein hadn't done it, something else would
    have in the next few years; the creation of General Relativity is
    however considered sui generis.)

    You words above say in paraphrase that Einstein's gymnasium instilled

    them. Not exactly a ringing endorsement.

    That is not the case. Maxwellian electrodynamics predicts that light
    travels at a constant speed in vacuo. That is inconsistent with the
    Galilean transformations.

    It is this contraction

    You mean contradiction. Contraction plays a role, of course, in the theory.

    between classical mechanics (Galilean-invariant)
    and classical electrodynamics (Lorentz-invariant) that led to the
    development of Special Relativity.

    Nope, that is merely your ignorant misrepresentation,

    Yes, but it only predicts that in the frames
    in which the Maxwell equations are valid.
    It isn't known, and it cannot be known beforehand
    which frames that are.
    It took Einstein's genius to see that this must be all frames.
    (Maxwell himself died before he could begin to really think about it)

    It is this contraction between classical mechanics (Galilean-invariant)
    and classical electrodynamics (Lorentz-invariant) that led to the
    development of Special Relativity.

    The irony of it is that Lorentz himself firmly believed
    in a universal and stationary aether. (and he never gave up on that)
    His theory is nowadays caled 'Lorentz Ether Theory', aka LET,
    and it can be shown to be fully equivalent to special relativity.
    (because the aether is unobservable to all orders of v/c)

    Nevertheless it is stil used by some researchers who want to develop
    new theories, beyond special relativity,
