Happy Pi Day
πToday, March 14, is Pi Day. Pi is often approximated as 3.14, so apparently 3/14 is a day to celebrate that famous irrational number. It also happens to be Albert Einstein’s birthday. I’m not sure what you’re supposed to do in celebration, but here is Pi to one million digits.
The Wikipedia entry on Pi Day points out:
.The “ultimate” pi moment occurred on March 14, 1592, at 6:53 AM and 58 seconds. When written in American-style date format, this is 3/14/1592 6:53.58, which corresponds to the value of pi to twelve digits: 3.14159265358. However, considering this was well before any kind of standardized world time had been established, and the general public had no concept of π, the occurrence likely went unnoticed.

This calls for a Pi-eyed celebration!

Happy Pi Day 2009
Here are some facts I have assembled:
The first clock with a minute hand was invented by Jost Burgi in 1577.
Ludolph van Ceulen published 20 digits of Pi in 1596. At least 11-16 digits were known before his time.
The Gregorian Calendar was inaugurated in 1582 and used by several European countries.
It’s quite possible that some mathematician with a clock could have made the Pi Day connection to 10 digits, but the closest anyone else could get would be 3/14/1592. However, it really doesn’t matter because the date formats such as mm/dd/yyyy (or dd/mm/yyyy) weren’t in use until modern times.
This pretty much rules out any possibility of anyone realizing the significance of 53 minutes past 6 o-clock, on the 14th day of March, 1592.

I always celebrate Pi Day every March 14th! And since each one is too far apart, I also try to catch 3:14 on a clock as much as I look for 11:11. And it’s also a happy moment when my total when buying something is 3.14 or 31.41.
Yup, I’m a total math nerd.

Looks like I will celebrating Pi Day again by posting on this wall. 50 more minutes to go.
