But their dependence on the Nile did not (as far as I know) change during the decline. It was more likely moral decay that caused such a decline.

I'm very stupid with programming, so please be kind. How do you include those latex or whatever they're called graphics in posts?

I know calculus, like I said...?

What point did I miss?

How the hell did this guy make an elephant disappear without any mirrors, ropes or trapdoors in the pavement, if anyone saw that episode. The nature of these magicians simply confounds me.

I believe in direct democracy. People say it isn't possible in a society as large as ours, but there is such a thing as the internet.

People do stupid and unusual things that would not normally be in their nature under stress, like the threat of communism. It's a natural response.

Weird. But I'm sure it's catalogued somewhere.

And a manifold, what's that? So many questions!

Also, what is a tensor?

I know that, like the pythagorean theorem in 2D space, but what is the theory behing the metric of the spacetime, like quantum foam and whatnot.

I'm a layman here, so please put any answers in terms that a layman can understand. You can use calculus though :) What is the spacetime metric, and what are the equations describing it?
