π, we've got π...

It looks like I have the day off, as nobody has called me for a job. Fine with me, since today is the most important holiday of the year for math teachers: π Day! Yes, this is the day (3/14) when we celebrate the ratio of the circumference of a circle to its diameter (3.14...). So, here are some links to celebrate the day (which, by the way, is also Albert Einstein's birthday):

• Here's a rerun: A Musical Tribute to π (a good one to have on in the background while you browse the rest of these links). Ooh! And here's the complete song as an MP3 file!.
  
  
• Another rerun: π to a million places, which has one of the best URLs I've ever seen: http://3.141592653589793238462643383279502884197169399375105820974944592.com/.
  
  
• π Day activities here and here.
  
  
• π Day in Wikipedia
  
  
• π Day resources, which also reminds us that this year sees the tricentennial (that's three hundred years, doncha know) of π being used as the symbol for this all-so-important number.
  
  
• So to celebrate this day, send your sweety-π a π Day greeting card!
  

I think, later today, Laura and I are going to go out and get some custard tarts to celebrate. (Well, they are small pies...)

UPDATE: Yup, Laura and I ate custard tarts. At 3:14 p.m., no less. (Not that she was terribly happy waking her up from her nap then. And she couldn't wait, she started nibbling at 3:13...)
