comment Stupid yet tricky question: Why do we actually see the sun?
"which you know to be longer than, say, 1/60 of a second, given that you don't see most monitors flicker" - The reason you don't see most monitors flicker is because TFT monitors don't flicker so much at all. For CRTs, they did flicker and this was also easy to see. You don't really think that we see a 60 Hz stroboscope as a continuous light, I hope?

comment Text interpretation in Griffith's intro to QM
2.14 is pretty much equivalent to saying that every vector can be written as a linear combination of a set of basis vectors.

comment Is Feynman's explanation of how the moon stays in orbit wrong?
"shouldn't the amount of "fall" travelled by the moon increase over time?" - no? The moon is being accelerated downwards, but because it's going forward so fast, all the previously accumulated velocity is now in the forwards direction. "The moon's speed toward the earth accelerates" - This is not true. You need to realise that the direction towards Earth, 'downwards', is constantly changing.

comment How long can you survive 1 million degrees?
Simply touching something at a high temperature is not necessarily a problem if its heat capacity is really low.

comment Why quantum entanglement is considered to be active link between particles?
@Chad: Isn't everything indeterminate until a measurement is made? If no one checks either the glove at home or the glove in your pocket, then it will remain unknown which one you have.
