Dirac's paper on QM of Electron
|
| |
I'm trying to read Dirac's paper "The Quantum Theory of the Electron."
I am really struggling with the first displayed equation on 611. Is
there a sign error? Should it read something like:
F = -(W/c - eA_0/c)^2 + (p + eA/c)^2 + m^2c^2?
I googled the Klein-Gordon equation, which Dirac is motivating in this... more »

Hi Mercury:
I am going to refer you to my paper below, which was just published on
April 30, because it is exactly on point to your question: J. Yablon, "Predicting the Binding Energies of the 1s Nuclides with High
Precision, Based on Baryons which Are Yang-Mills Magnetic Monopoles,"... more »

What would the graphs of the following to cases look like?
1. The body is accelerated non uniformly along a line and then continues
moving with non constant acceleration along the opposite direction
i.e. back to where it started from.
2. The body is accelerated non uniformly along a line and return to... more »

Friends,
I wanted to let you know that my recent second, third and fourth peer-reviewed
papers were all published on April 30. These papers, in order of logical
development, are:

Product rule for functional derivatives?
|

Hi alltogether,
Consider Lagrange formalism, e.g. Lagrangian mechanics. We have a Lagrangian function L(q, dq/dt) where q is a generalized coordinate and dq/dt its time derivative. Now, according to Hamiltonian principle, L ist stationary with respect to variations \delta q of the trajectory q(t):... more »

Hi,
my name is Roberto Bovolenta, and I?m an Italian physicist. In former
times I?ve worked in the fields of nanoscience and acoustic, and
recently I got interested, on my own, in quantum computation world.... more »

I tought is there any explicit mechanism realizing the mass defect.
Something in terms of gravitons or virtual photon. Maybe it looks... more »

one-way and two-way speed of light measurement.
|
| |
suppose, at the outset, that we revert the definition of the meter to
pre-1960, so that the speed of light is something to be measured,
rather than defined.
i remember reading about Michaelson's original experiment that
measured the two-way speed of light using a reflector on a mountain 35
km distant. i'm pretty sure i understand the mechanics of that... more »
