comment Do photons emitted from a LED show bunching?
Yes, if you have a giant LED but you ONLY look at the 0.1% of photons that are coming out from a particular part of the chip and/or coming out in a particular direction ... then that subset of the photons can have bunching or anti-bunching.

comment How does DC current work in Cathodic Protection?
I would say that the important thing is the DC voltage, not the DC current. The voltage prevents corrosion, the current is an inevitable side effect of applying a voltage.

comment What is the pressure of a charged gas?
@BlackbodyBlacklight - The "novelty glass globes filled with fluorescent plasma" is not an example. Even if it were completely ionized, it would be a mixture of positive and negative ions.

comment Order of magnitude for the range of vision
I don't understand "eye can't reach". We can easily see stars trillions of miles away.

comment Silicon parabolic dispersion for X minima
"Assuming the six equivalent bands are ... spherical" ... but they aren't. The energy rises more sharply in some directions than others.

comment Dr. Pierre-Marie Robitaille: On the Validity of Kirchhoff's Law
You are being too kind--indeed inaccurate--by calling it "highly controversial". He's completely wrong and everyone knows it. There's no "controversy" here at all.

comment Silver vs Aluminum electrodes in silicon solar cells?
You need an ohmic contact to n-Si, and an ohmic contact to p-Si. Can aluminum be both? I thought it could only be one of those (I forget which).

comment Are there measurable quantities which directly depends on the Fermi velocity?
As soon as the Fermi level is away from the dirac point, vF has an obvious importance--density of states in particular. I guess I'm saying, it's easy to say in theory "I assume Fermi level is exactly at the dirac point", but it's not only impossible in practice, but stops being true as soon as you do something as simple as apply a voltage, even in theory.
