imagine a place with ferns as far as the eye can see, the sky is always gray, a dense fog constantly presses down the place, there are no trees, and the ferns sway even though there is no wind. there is no sound except your beating heart, nothing else. you can't even hear the ferns. not even a compass works in the barren place. what would you call that place?

Why does the wave function collapse upon observation?

Given that an observer is composed of matter, and therefore governed by the same quantum mechanical rules as the object he is observing, what property of the observer causes the wave function to collapse, and a certainty to replace it, once the event in question is observed?
ie, if I toss a coin, and prior to looking at it, it represents a probability function with an equal chance of being heads or tails, what compels it to be heads, or to be tails, when I observe it? For that matter, what mechanism makes the selection 'heads', or 'tails', between two equal probabilities?

Government conspiracy about the moon landing?

What's up with all the people who say they "believe" that NASA faked the lunar landings? If it were just a few misguided individuals, that would make sense, because there's always a few out there that can't figure out how impossible it would be to accomplish such a coverup and choose to ignore rational explanations of what they consider to be evidence of a hoax, but it seems like there's thousands or millions of them!

The only explanation is that the government is secretly trying to make it look like the average American is an idiot, so our enemies make the mistake of underestimating us. It's a conspiracy, I tell you!

Can someone explain and/or give a reference for deriving the Green's function in spherical coordinates?

Under certain circumstances we can "explain away" certain dependencies. I am looking for the complete form and not one without a phi or theta dependence. Also, can this be represented as a series?
