Hey folks. It’s that time of year again! To celebrate one of the greatest mathematical constants in existence, I took this photo and spent the afternoon at San Francisco’s Exploratorium. I wasn’t the only one either…Special note: today was also 3/14/15, which is the most accurate calendar listing of pi digits you’ll ever see. For another 100 years, anyway!
How’d you get your pi on this weekend?
