I am just nuts about doing physics. I love working on almost any little thing that even kinda seems cool, and then trying to see all the different ways it looks. I love forums websites about physics because I find in real life people don't want to talk about physics in a fun way for some reason, although sometimes there are people like that online too...

I'm never gonna stop trying to learn more and more until I die.

answered How do we prove that two conjugate operators $X$ and $Y$ induce $\sigma_x$ and $\sigma_y$ driving terms when restricted to a two level subspace?

comment Getting Deep into Drift Velocity
@Pooya Jannaty the equation says directly that for a fixed current and a varying cross-sectional area, the velocity changes... can you elaborate on the independence of A please?

comment Do charges attractions cause time dilation?
Special Relativity (for flat, Lorentzian spacetime) can describe acceleration, and indeed there are effects. You should be able to find a treatment in a intro relativity textbook.

comment Do charges attractions cause time dilation?
Ignore relativity for a second here, why do you think it is okay to write $v=a$? When is is ever okay to write 2 centimeters equals 2 liters? The answer is never. Acceleration and velocity are two distinct things that are never equal. You must understand this before going further.

comment Dirac equation as Hamiltonian system
@firtree I think you should end up with more terms then something proportional to mass only. Check my answer up above and see if that is correct and you get the same thing.

comment Zero photon energy in moving frame
There is no photon rest frame, it violates the principle postulate of SR: [\begin paraphrase] the speed of light is 'c' in all frames of reference [\end paraphrase].

comment Why is information indestructible?
This post sounds so cool, but It's a little hard to follow... Can you make the reconstruction part more specific? Where are some of the numbers coming from?

If you had to guess as to what the square of the momentum operator looked like, what would you guess?
