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.

comment A trace formula of two noncommutative operators
Why doesn't $U_{I}$ need $\exp(-i/\hbar H_{0}\Delta t)$ on the right side?

comment Geometric interpretation of quantum Yang-Mills field
@ACuriousMind There is nothing in any theory! all we do is interpret, it's called "physics." Why don't you think there is any geometric relationship to particles? So far every part of physics has been geometry, even the algebra parts...

comment Why don't we take this term $D_{\mu}D_{\nu}F^{\mu\nu}$ in Lagrangians?
@Olof Oh duh, you are right! I was only thinking of the partial derivative part in my mind... My bad. It's the definition of the curvature lol. I agree.

comment Why do non-accelerating objects exert force on each other?
I say this answer is a better description of what is going on. Really the OP is interested in the relation $\vec{F} = d\vec{P}/dt$. Here the force is related to the change in momentum, or for fixed mass, change in velocity in time.

comment Why does the field of an electric dipole drop off as $1/r^3$?
Thank you for the first sentence of this answer. I assume this is what the OP wanted. "Have you tried deriving it yourself blah blah..." is useless since you can't set up the first line you wrote without the physics, which is the near cancellation. I'm glad you wrote that.

comment Can we quantitatively understand quark and gluon confinement in quantum chromodynamics and the existence of a mass gap?
this link also has a more general proof: dx.doi.org/10.1016/0550-3213(77)90086-4

comment Can we quantitatively understand quark and gluon confinement in quantum chromodynamics and the existence of a mass gap?
Why do you say "cannot be?" You should say "has not been?" For example, 3d electrodynamics is a confining theory and has been shown to be so. The proof is completely non-trivial. QCD could also be proven, but it is also completely non-trivial.

comment Finding the vacuum which breaks a symmetry
Maybe It's a little above my head, but the potential you choose decides how the symmetry is broken. Are you asking how do you choose your potential?

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.
