According to reference [1] in Does the act of storing information (not its erasure) locally increase entropy in Maxwell's demon's memory?, information-theoretic entropy and thermodynamic entropy may not be the same. My question comes in 2 parts: i) If they are not the same, then which is more fun...

Recently, my teacher just told us that intensity is not linearly dependent on temperature and that it's ONLY dependent on photons. But then, what about Boltzmann's law? Isn't intensity dependent on the fourth power of absolute temperature? Even if you only consider temperature, we do observe that...

I recently stumbled upon a video (1) which explained that what is assumed to be the speed of light is actually the two-way speed of light. As explained in the video, hypothetically the speed of light varies across different directions of spacetime. If this is the case, then how is it possible tha...
