comment What would put a harddisk drive (HDD) under 350G's of force?
@NateEldredge What the manufacturers guarantee will generally be much less than what it can actually handle.

comment Why does string theory require 9 dimensions of space and one dimension of time?
@Jiminion As in you have to arbitrarily label them; there isn't a universal "up".

comment Are universally valid possibilistic theories possible?
This seems metaphysical to me.

comment Have red shifted photons lost energy and where did it go?
@bobie Asymptotic is asymptotic, regardless of the size. I never didn't accept that energy can be drained out. It can. However, again, the photon started with a net negative "potential energy", so everything evens out.

comment Have red shifted photons lost energy and where did it go?
@bobie It can't be completely drained out until it reaches infinity (or if it is beyond an event horizon). General relativity doesn't have a nice concept of "potential energy", however remember that a gravitational well has negative PE, so throwing an energetic photon up (and having it redshift into oblivion) conserves energy.

comment Green's function for a dielectric with a charge
It needs to ask about a specific concept, too. Showing work is secondary (see the linked policy for mode details)

comment How many wavefunctions are in a minimal basis set for benzene?
Note: Chemistry is fine with this question, but so is Physics IMO.

Bounty refunded and question closed. This is off topic by our policy on engineering questions, as agreed upon on meta

comment An electron has no known internal structure, does that imply it has an unknown one?
From whatever scattering experiments we have done, the electron seems to exhibit no further break down. Spin is a property that doesn't require "spinning" particles. It can just exist as a property of the particle.

comment Which form of the first law of thermodynamics should I use?
Ah, okay. I just used the symbols from the question (otherwise I almost always use $\delta$). I'll edit my answer later today.

@Wildcat care to explain why?

comment Is sea water more conductive than pure water because “electrical current is transported by the ions in solution”?
@AJP yes. This takes time (forever) though, since there is a solid-ion equilibrium for the impurities, when the ions start disappearing ions are created from the solid. But it will try to maintain the equilibrium so the number of new ions will be much smaller. This process will go on, effectively to infinity since the equilibrium laws won't let the amount of solid or ions disappear completely. Practically, there will be some point when these numbers become too small, but again, practically this is very far off.
