  1. but that is in the place of the rate in m/s of the expansion of the universe.

     

    How does that make it any less undefined?

     

    And E(NC)or M(NC) are neutral representations.

     

    Define "neutral representation."

  2. A little symplectic and Poisson geometry in relation to the Hamiltonian description of classical mechanics would be useful for canonical quantisation. Connections, geometric phase, gauge transformations etc come later and not as an introduction I would say.

     

    That's true, but it's probably not something the OP should devote a massive amount of time to if he just wants to get a good feel for QM. Though I'd say it's definitely worth spending the time on once he gets into relativistic QM and QFT.

     

    My high school in New Jersey did not.

     

    Haha, where in NJ? Monmouth county reporting.

    • There are lots of different constants: permittivity of free space, Planck's constant, the speed of light, the gravitational constant, the fine structure constant, etc. So it's not clear what you mean by "second constant."

    Define "energial."

    Define "physical."

    Define E(NC).

    Define V.

    ∞/0 = undefined.

    What does this have to do charge?

    "Energy" does not have charge.

    What does this have to do with expansion?

  3. "observers rest mass plus momentum is mc^2"

    It's wrong, I make mistakes too ;)

    Okay, but what about the rest of the comments/questions you've received? You seem to be selectively ignoring the parts that don't bode well for your "idea." Nobody has the slightest clue why you keep insisting that velocity is somehow equal to some kind of electrostatic potential. Your "equations" look like they came about by taking several disparate quantities you found while browsing wikipedia for a few minutes, and trying to staple them together without any real understanding of what they mean.

    Ajb,

    Bring me a stable fermion heavier than the proton, and I shall reconsider my case :)

    What does that have to do with his question?

  4. At every time t an object will have an associated velocity vector, v(t). We define the speed of the object at time t as |v(t)|. It's a definition, so it's not really something you can ask "why" about.

  5. There is uncertainty in observable quantities like acceleration. Plus, acceleration is not really a useful concept in QM. I think a better question to ask would be, "what is the probability for an electron to start at A and be detected at B in time t?" The answer is an amplitude called the "propagator," which is defined as: [math]K(x,x',t)= \langle x'|e^{-iHt/\hbar} |x \rangle[/math]. The amplitude squared gives you the probability.

  6. In the UK some very very basic quantum mechanics is taught at high school. They don't see the Schroedinger wave equation, operators or anything like that. They meet wave particle duality, electron diffraction, the photoelectric effect, Planck's law and atomic spectra. There you are, if one is looking for a place to start one could google these terms.

     

    Yeah, my high school in New Jersey taught basically the same stuff to the upperclassmen.

  7.  

    Possibly with a wink in my direction.

     

    ;)

     

    I was joking as well. :P

     

     

    Then you're both in wrong section.

    Joke section is here

    I just wanted to show you experiment, that everybody is learning at school, but nobody is performing in real - after all how many of you have vacuum chamber with dozen meters height...

     

     

    Oh boy, sorry about the thread derail.
