MNEMONIC for Pi

MNEMONIC

What's come in your mind when your hear this? Mnemonic? For those who knew it, maybe the colour of the umbrella will come to your mind?

"Richard Of York Gave Battle In Vain = Red, Orange, Yellow, Green, Blue, Indigo, Violet."


But for those who doesn't, mnemonic (Longman dictionary) stands for something such poem or sentences that you used to help you remember certain rule.

It maybe useful to us, not just to remember scientific facts but it also helps in language acquisition and mathematics.

I'll give you example in mathematics. Do you know pi? Pi represents number for the distance around a circle and the diameter is the distance across it.
The basic pi in our curriculum system is 3.142 or 22/7.  Is only costs us 3 decimal places. Do you know that a Japanese, Akira Haraguchi can recite up to 100,000 digits of pi.

The first fifteen digits are:

"the wife and children have gone abroad;the husband is not scared" 

 I try to make sense but i just can't help it. I thought I'm a mathematician enough to translate it to numbers.
Maybe the wife is 1, children is 4 and the husband is 1; which represent .141

An English use a simpler  mnemonic to remember pi;

"how i need a drink, alcoholic in nature, after the heavy lectures involving quantum mechanics. All of thy geometry, Herr Planck, is fairly hard"

The numbers of the letter in every word represent the digit in pi.

Sometimes most linguist will say that numbers is hard; and most mathematicians say that language is hard to consume. Maybe our brain need helps, try mnemonics.
