Let's Get Literal: Calculating Pi With Pies. Actual Pies

Thursday, March 14, 2013 - 11:39 AM

 

Today is March 14, or "3/14," the first three digits of Pi. It's a day celebrated around the (geek) world as "Pi Day." Pi, of course, is the ratio of the circumference to the diameter of a circle. It was first recorded by Archimedes, but you can replicate his discovery in all kinds of ways.

Here's the pie version of Pi, the down, dirty and baked goods approach, illustrated by Brady Haran, a video journalist who loves numbers. He's in an ordinary parking lot. He unpacks an enormous number of identical, small pies — I can't tell what kind of pies, they look like a dense jam, maybe apple? Prune? But these aren't for eating, they're for counting ... and the math works out ... almost perfectly.

He could have saved about 42 pies and a little time if only he had forgotten all about Pi and went straight to figure out Tau instead (viz. http://tauday.com/). Besides, the "cool factor" of that would be higher. :-)

They're bound to be meat pies. Fruit pies are not a thing in the UK.
