All math-lovers have a special occasion today – a magical once-in-a-century Pi Day. It’s an international day which honors one of the most recognizable mathematical irrational symbols – “pi” or “π,” proving once again that math can be fun.
This Saturday, March 14, 2015 is 3/14/15 in the US date format which corresponds to the first digits of a mathematical constant Pi: 3.1415. The best time to enjoy all the ‘irritability’ of today’s day is to celebrate it at 9:26 and 53 seconds, morning and evening as then the time matches with all 10 digits of Pi: 3.141592653.
The holiday happens once in 100 years and the true fans of Pi should really savor the moment as the next time it happens will be in 2115. For the admirers of general theory of relativity it’s also an occasion to celebrate Albert Einstein’s birthday, which is also March 14.
“It’s the Pi Day of the century,” Michael Breen, public awareness officer at the American Mathematical Society, told The Boston Globe. “There’s a lot going on to celebrate.”
According to University of California Berkeley mathematician and author Edward Frenkel, Pi is special as “it’s a portal into this magical mysterious world of mathematics.”
