It’s Pi Day tomorrow! A very special Pi Day, because on March 14, 2015, at 53 seconds past 9:26 AM the date and time will spell out the first 9 decimal digits of the constant π. I’ll be celebrating by eating pie.

This GIF is a visual representation of C = 2r*π (the relationship between the circumference and the diameter).

*These smart folks have pretty much convinced me that Tau (τ=2π=6.2831…) is actually a better constant. And on Tau Day (June 28th), I get to eat TWO pies. But we have to wait until 2031 to get those extra decimal digits for τ.
