The Khan Academy has a very basic introduction to the properties of circles, including pi. They also have lots of other math lessons, plus lessons on science, art history, chemistry, biology, history, economics, and lots of other fields. Pick one and maybe you'll learn something new!

And if you don't want to watch 'em on the web, you can use their free iPad app!

We didn't get to the last digit of pi yet

1949: The ENIAC computer computed 2,037 digits of pi in 70 hours.

1959: An IBM 704 computed 16,157 digits of pi in 4 hours and 20 minutes.

1961: An IBM 7090 computed 100,000 digits of pi in 8 hours and 43 minutes.

1989: An IBM 3090 computed 1 billion digits of pi.

1999: 200 billion digits of pi.

2005: 1.24 trillion digits of pi.

Current record: Japan’s T2K Supercomputer computed 2.6 trillion digits of pi in 73 hours, 36 minutes.

60 Minutes did a report on the Khan Academy a few weeks ago. The learning technique is intuitive, but not suited for schools in the poorer districts.

Yay pi day! Here is a fun way to approximate pi.

Happy Pi Day 2013

For some unexplainable reason, Sir Cumference and the Dragon of Pi costs $7.15 instead of $3.14.

A potion has changed Sir Cumference into a fire-breathing dragon. Can Radius change him back? Join Radius on his quest through the castle to solve a riddle.

Thumb resize.

Who is ready to challenge the world's record for the fastest time to recite the first 100 digits of pi while balancing one-legged on a balance board, manipulating a basketball and bouncing a golf ball on a rubber mallet?

Come to think of it, how many people have tried to set such a record?

Although it is actually a slightly closer approximation to Pi than 3.14

Happy Pi Day 2014

Who's ready for the MIT cheer?
Cosine, secant, tangent, sine, 3.14159.
Integral radical mu dv
Slipstick, sliderule, MIT!
And speaking of March 14, Happy 135th Birthday to Albert Einstein. I hope he divides the circumference of a pumpkin by its diameter to make some dessert. Yum!

I spend most of my time doing something special, so to mark the Pi-cassion I'll do nothing special for one second. (Actually, when rounded off the time is 1:59:27.)

Of course, real geeks should use infinitely accurate clocks and celebrate Pi-time for an infinitesmal length of time.

I know that pie is 3.1415...
I think that's pretty good.

----------

I just realized something! Pi next year pie day will be on the day 3/14/15 witch is exactly the first 5 numbers in pi.

One of the first programs I wrote when I learned to program was named QFR4NO, pronounced "Q-franno". It stood for "fractions for numbers" and it computed increasingly accurate fractions for a given decimal value. It found 22/7 for pi but next reported 355/113, and that's still a fairly-easy-to-remember approximation.

I know everyone's first program is supposed to be "Hello world", but I'm never one to follow the rules.

Yes, Happy Pi Day, everyone! I contemplated making little pies with pi marked on them, or door posters, or some darn thing, as I have variously done on Pi Day in the past, but settled for letting Bing do all the work this year...

http://www.bing.com/images/search?q=pi+day+images

I think my favorite of the fetched images might be the "Have an Irrational Day" pin. Take off the 3.14 annotation and the whole world could wear it 24/7/365, or so it seems to me lately
