MathWorld is back!  If you have a mathematics question, go there first.  Or just go and browse for something that interests you.   When I was working on the Course Designer for the Jack Nicklaus 4 golf game, I spent hours looking for information that I can now find in seconds at MathWorld.  They even have a good discussion of polygon triangulation–something I never did find back then.

I wonder if all this stuff is collected in a book somewhere.  I’d buy it in a minute.
