The Amazing World of √2

For instance, did you know that the two sides of a sheet of A4 paper differ by exactly √2?

Let Numberphile get irrational and you’ll learn something in the process. And if you’d like to make your browser very angry, here’s a website that continually calculates the decimal expansion of √2.

Finally, in “things I learned today”: To type the “√” on a Mac, just hit Alt+V! We’re learning all kinds of stuff, aren’t we?
