No, there is no misspelling in the title of this post. 3/14 is Pi day. I am not making this up, for real! Here’s a link and remember that you can believe everything you read on the internet. http://www.slate.com/articles/health_and_science/science/2015/03/pi_day_2015_ten_digits_represented_on_march_14_at_9_26_53.html
Saturday is March 14, or, as it’s written in the U.S., 3/14. That makes it Pi Day, because the mathematical constant π is roughly equal to 3.14. Nerds celebrate this date every year, because, well, we’re nerds. Duh.
But this year’s π Day is special: It’s the year 2015, so the date is 3/14/15, giving us two more decimal places of the famous constant. In fact, if you celebrate it at 9:26:53 today, you get π to nine decimals: 3.141592653. Since the next digit is a 5, you can even round up and celebrate π Day for an extra second.
