Friday math movie: Pi Day Song

By Murray Bourne, 11 Mar 2011

Next week it's Pi Day (3/14). To commemorate, here's Pi Day Song (Lose Yourself in the Digits).

The current record for memorizing the digits of pi is held by Akira Haraguchi, 59, who "managed to recite the number's first 83,431 decimal places", according to the BBC.

There's one incorrect definition in the video. Can you spot it?

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
