comment Are voltages discrete when we zoom in enough
Okay maybe I couldn't make you understand my question. I wanted to ask from where you get these information: "Capacitance is a function of the shape, size and distance between objects". Do you use C=$\frac{Q}{V}$ to get these information? Or can they be known from something else? In the latter case I am OK with your answer. But if we need C=$\frac{Q}{V}$ to get those information I think Floris' answer is better.

I think C is defined in terms of Q and V (maybe I am wrong, and in that case I seek clarifications). And from that you get these informations: "Capacitance is a function of the shape, size and distance between objects". Again you are using these informations to tell something about V? I think Floris' answer is better.

I think you are getting this inconsistency as you are breaking continuity equation by taking only a finite current carrying wire alone.

comment Doubt regarding Ampere's Circuital Law
see the magnetic field is still tangential. And I agree with you that in the case of finite wire the magnitude of the $\vec{B}$ depends on z also. But it doesn't depend on $\phi$ which is important in this case of line integral. As it doesn't depend on $\phi$ you can still take the magnetic field out of the integral and you have B(r,z)=$\frac{\mu_0 I}{2\pi r}$. But this is inconsistent as left hand side shows dependence on Z (so our intuition is) but right hand side shows no dependence on Z. I think this is what OP's question is.

comment Doubt regarding Ampere's Circuital Law
"where it is obvious that the B-field should not just depend on the radial coordinate, so our simple calculation fails": I think if you apply Biot-Savart law you can see toward the end too it is still tangential to the circular loop. And that is where I think OP's question is. I think the probable answer is: we can't take only finite straight current carrying wire without violating continuity equation.

comment Unitarity of PMNS matrix
I don't know whether you are getting my question or not. I want to ask whether Hamiltonian is Unitary always. DO you mean $H^{\dagger}H=I$? Then again $H^{\dagger}=H$ ,so that $H^2=I$? And you know the consequences of this. All the eigenvectors are degenerate, moreover all the vectors are eigenvector of $H^2$.

I knew the Hamiltonian must have to be Hermitian. But should it be Unitary also?

Do you really mean this: "The Hamiltonian for any system must be unitary"?

See figure.4 and read the 2 flavor case from this.

comment If a neutrino has a rest frame, why can't a photon have a rest frame as well?
I am confused here :"Unfortunately, a single dimension is not sufficient for a frame of reference for four dimensional space time" . Can you please explain it elaborately?

comment Post Problem Analysis - Rod in a cylindrical time varying magnetic field?
That one tells you can't determine electric fields uniquely. Maybe you are taking some particular choice. If you tell on which choice your results are based, then it may be easy to tell about the higher potential.

comment What exactly is an anti-neutrino?
I am confused here:"——that observer would consider it a right-handed neutrino. Would a right-handed neutrino act like an anti-neutrino?". Ok then that observer would consider similarly the right-handed antineutrino in some frame as left-handed antineutrino in his frame. So what is the justification of "Would a right-handed neutrino act like an antineutrino?".
