By Murray Bourne, 13 Mar 2007

Tomorrow is Pi Day, celebrated because π is approximately 3.14.

Some interesting stuff related to Pi:

## Remembering the Digits of Pi

For a party trick (or if you have no life), try learning the digits of pi.

Here is George Polya's mnemonic for the first fifteen digits of π :

How I need a drink, alcoholic of course, after the heavy chapters involving quantum mechanics

[The lengths of the words are the digits. George Polya was very influential in mathematics education, especially in problem solving.]

## Want to try to Remember All These?

From the BBC:

In September 2002, Pi was computed to 1,240,000,000,000 decimal places by Professor Yasumasa Kanada at the University of Tokyo. It took over 400 hours on a Hitachi Supercomputer.

## New Pi Page

Getting into the spirit of the day, I added a new page to the Interactive Mathematics site today: Pi.

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.
