Today is 3.14

Here in US, we celebrate today as the Irrational Exuberance day. (We might have as well called it the Alan Greenspan day). People – especially those who do not remember what the definition of pi is (not the value) – get together and have pies and pie parties.

The rest of the world looks at us completely bemused. I am sure they go something like “Dude, you don’t even know how to write dates properly. You either go up DDMMYY or down YYMMDD. And by the way, the pie that you eat is not spell the same way as pi – the math symbol. In fact, there is an extra “e” in it – which is another math symbol that you probably neither know the definition or value of”.

In response, we pop in one more Tums. Because we have run out of pies.

Jokes apart, did you know Belize is the only other country than US that uses MMDDYY format? (There are a few other countries like Kenya, Philippines etc where, in some parts, MMDDYY is also used)

    22/7 is Pi Approximation day. We had a small celebration of Pi Day at work yesterday. I shared something I picked up from the 22/7 we used in school. it translates to 3.142857. Try multiplying 142857 with any number (start with 2) and watch the digits jumble in front of you. What you get when multiplied by 7 is also the Feynman Point.

    Isn’t that tied to the fact that it is a six digit number divisible by 11? If I took a large number with distinct digits that is divisible by 11, wouldn’t I get the same pattern?

    Rajib – never thought of the why. But, now that you ask, I am curious why you thought of 11 as the factor? Wouldn’t being divisible by 9 a better guess?

    No. Digits repeat themselves when multiplied if they are divisible by 11. Because the difference in odd placed digits and even placed digits have to be 11 (or multiples thereof), I guess

    What i have learnt after coming to usa that 22/7 is close to pi not equal to the value of pi. It differs from the value of pi at the 4th decimal i guess.
