Pi Status Update T-ShirtsPieter posted in "Goodies". 2 years, 1 month ago
For most people, March 14th is just like any normal day. But for math masterminds ─ok, just call us geeks─ it’s the day we celebrate π (pi). Being 3/14 in the month/day date format, it looks just like the first three numbers of the mathematical constant: 3.14159265358979323846264338327950288419716 and so on. Hence: Pi Day!
To be profound, Pi Day also has a Pi Minute (3/14 at 1:59 AM) and even a Pi Second (3/14 at 1:59:26 AM), which resembles π truncated to respectively five and seven decimal places.
In Latin American, European and Asian countries where the dd/mm/yyyy date format is used, there’s no 14th month and 3rd day to celebrate Pi Day. But they can celebrate Pi Approximation Day on July 22 (22/7), since the fraction 22⁄7 is a common approximation of π. In fact, it is actually closer to the irrational number than the decimal approximation of 3.14.
Why all this talk about pi? It’s because we made two new Facebook status update t-shirts for the number crunchers and π-lovers among us. Order them today and get the t-shirts in time for Pi Day 2011! Or wear them all year round, just ’cause π rules.
