comment Neutron decay and particles
@zoran404 in Feynman diagrams, anti-matter particles have arrows that point "backwards" from their normal-matter counterparts. It doesn't represent "movement" or "time", it's just a convention to distinguish matter from anti-matter. The anti-electron neutrino and the electron formed at the same time and moved away from each other.

comment Is it possible that there is a color our human eye can't see?
@Ben if they "look the same to us" that implies we can see them, or they wouldn't "look" like anything; it depends on how you interpret the question as "are there colors we cannot distinguish" or "are there colors that are invisible to us", I suppose...

comment Is wave–particle duality considered a valid interpretation of the behavior of photons?
that makes sense; though in QED Feymnan actually does use QED to calculate the results of Young's experiments, but I guess because it's a famous experiment he kinda had to?

comment Is there any thing other than time that “triggers” a radioactive atom to decay?
I think you would be interested in the first part of this Feyman lecture where he explains the idea that nature is not deterministic (with typical Feynman bluntness: "if you don't like it, go find another universe.") - vega.org.uk/video/programme/45

comment How do electrons know which path to take in a circuit?
+1 the door analogy is probably one of the best I've heard.

comment Are “typical” black holes rotating, or stationary?
If you could make that an answer and find a source for that observation that's exactly what I was looking for!

comment Are “typical” black holes rotating, or stationary?
Yes, sorry, that's my sloppy wording I think; there are two solutions that rotate and two that do not, correct?

comment Would it matter if the Earth rotated clockwise?
so far, all of the answers appear to be "what would happen if the Earth reversed direction" -- would there have been any major effects if the Earth had always rotated the other way?

comment Is the Avogadro's constant equal to one?
Avogadro's number isn't a measurement, it's a magnitude. It's the conversion factor between 1 mole and 1 atom, in the same way that 12 is the magnitude of the conversion factor between 1 foot and 1 inch.
