My daughter is Googling Euler's identity. Because it's in a book she's reading.

Euler's identity is possibly the coolest thing ever. I was bouncing the entire class period my math teacher explained how to derive it.

If she understands it, can she explain it to me? I'm trying to read up on the math behind the mobius strip and I keep seeing that it's Euler number is 0, and I don't really understand what that means.

That's the Euler characteristic - Euler was crazy prolific. Tons of stuff named for him.

Ah, I see.

Didn't a young lady have it branded on her back at Pi-Con last year?

Ah yes, here it is:


I vaguely recall a story behind it.

Euler is my favorite. The best story is how he came up with his summation algorithm as a youth in school. The teacher was trying to teach arithmetic.
