As a kid in junior high, my friends and I used the expression "P.I." a lot. It stood for "public idiot", and we used it to make fun of someone when they did something foolish. Did we make it up, or has anyone else ever heard of it? Where did it come from (movie, book?)

Has anyone else ever had the insane/completely useless (save for its novelty) experience of having to memorize a certain number of digits of pi (52 in my case) for a middle school math class (or any class for that matter)? I had to do just that to pass my 6th grade math class. Was my teacher a little off or was she just trying to teach us the value of ..... something or other? (I still remember 26 digits, but that's as far as I can go.)

I am looking for a pie pan shaped like Pi. I need to make a pie for an upcoming pie party and I thought it would be fun to do it in the shape of the Pi symbol. If I can't find a pan I'll probably cut the shape of Pi into the top, but I was hoping one exists. However, Google hasn't turned up anything yet. Anyone know where I can find one online?

Can someone give me a reasonably simple explanation of why e raised to the power of i times pi is equal to -1? I've always had trouble understanding this and thought I'd try the green.

I just finished "Life of Pi" and I don't get it. I think I'm suffering from reading for the sake of reading and missed something along the way. Anyone care to share their take on this novel?
