comment Terminal velocity?
You mention "all collisions are inelastic"; are you given the amount of elasticity in the problem, or are you just speaking from your own thoughts on that one?

comment How do permanent magnets manage to focus field on one side?
Since I don't have this in front of me: Are you certain that the whole thing is actually a magnet? Is it possible that they are just backed with a thick layer of some similar-looking substance that prevents them from getting close together and exerting a strong repulsive force?

comment Triple slit experiment
But it does state that blocking one of the slits in the double-slit destroys the pattern. To my understanding, detecting the passing photon with minimal disruption to it does not destroy the double-slit pattern.

comment Triple slit experiment
True, but so does the original question.

comment Why do people rule out local hidden variables?
I will note that the free will vs. determinism debate often assumes that probability plays no role. You may be better served by thinking of not a sliding scale between "free will" and "determinism," but as a triangle with "randomness" at the third point. If there's a philosophy stackexchange site, that's probably the place to ask about free will.

comment Is quantum perturbation theory taught in college?
Additional supporting data points: It was taught in the undergrad classes I took at RPI. We did not get into field theory or second quantization.

comment Why do we think of light as a wave?
You are correct - that's what I get for simplifying my language too far.

comment Could someone remind me of what we mean by zero electric field “inside” a conductor?
"Inside a conductor" usually is taken to mean literally within the medium of the conductor - in the metal. The example @jak is using would normally be phrased as "in a pocket..." or "in a bubble..." or "in a cavity within the conductor".

comment Why do we think of light as a wave?
I didn't vote it down, but there are three things that struck me about your answer. First, it's a little incoherent and could be better organized. Second, you attribute interference patterns to particle behavior, when they're actually wave behavior. Third, you answered with material that seems to be way above the level of the original post, and would probably just be confusing. Those are probably why people voted your answer down.

comment Why do we think of light as a wave?
How familiar are you with electric charges and electric fields? If you know some about them, I can give an answer that is a bit more in-depth and accurate without having to explain electromagnetism along the way.

Ok! Just wanted to make sure. Thanks!

No offense, but this sort of sounds like a homework problem. Is it?
