    I Why M.Planck used Boltzman distribution to calculate average energy?

    I mean exp(-E/kT) is Boltzman distribution

    I Why M.Planck used Boltzman distribution to calculate average energy?

    As far as I understand kT defines scale of Boltzman distribution, i.e. avg. energy and Boltzman distr. are the same thing. And for me, Planck's move to find avg. energy different from 1/2kT from Boltzman distr. is like 1+1=2, 2-1=3.

    I EM wave decomposition to axis components in the Rayleigh-Jeans cube

    $$\lambda_x = \frac{L}{n_x} , \lambda_y=\frac{L}{n_y} . \lambda$$ does not fit the cube as integer. In the figure $$n_x=4, n_y=3$$

    I Where is the mistake in this derivation of Length Contraction?

    yeah, here is my wrong. Thanks!!!!!!!!! Now it fits perfectly!

    I Where is the mistake in this derivation of Length Contraction?

    Here, v=c/2. 1. When the vertical photon (photon V) hits ceiling of the box, thus traveling distance R, the emitter travels distance $$\frac{L_0}{2}$$ along the x-axis, the horizontal photon (photon H) also travels distance R along the x-axis, so that it is P-distance ahead of where it must meet...

    I Where is the mistake in this derivation of Length Contraction?

    here is my calculations for v=c/2. Diagonal arrows - path of the vertical photon, horizontal arrows - path of the horizontal photon, both photons travel distance 2*R=2*L*sqrt(1+1/4). I find contracted length by subtracting x1(path of the emitter when horizontal photon hits the wall) from the...

    I Where is the mistake in this derivation of Length Contraction?

    I tried to use square box with two perpendicularly oscillating photons to derive length contraction formula. Photons are emitted, reflected from box walls and absorbed simultaneously from the box's point of view. If the box have some velocity v, then assuming photons are still emitted and...

    I This gas work violates 2nd law of thermodynamics?

    heat of gas A goes to kinetic energy of the piston A, heat transfered via pistons, but there is no external work or something like that

    B E-field of a constant velocity charged particle

    its dipole moment has equal chance of pointing in any direction :)

    B E-field of a constant velocity charged particle

    you are right, even the hydrogen atom is a dipole, i.e. has a electric field

    B E-field of a constant velocity charged particle

    yeah, how is magnetic field relevant to my question? you have started talking about magnetic field

    B E-field of a constant velocity charged particle

    there is electric field though.
