The TED office is running in circles trying to get the word out about Pi Day, that special day for number nerds that only comes around once a year. We’d love to hear what TED fans are doing to celebrate — whether watching Pi, baking a pie or taking an irrational out to dinner.

If you’ve chosen to circumvent the fanfare, however, keep in mind that March 14th is also Talk Like a Physicist Day. (It’s Albert Einstein’s birthday, after all.) TEDTalks can help you brush up on your non-Newtonian oratorical skills with lessons from Murray Gell-Mann, Martin Rees and David Deutsch. – Matthew Trost
