In our home, the fourteenth of March is celebrated for three reasons: Valentines Day for Men, Albert Einstein's Birthday, and Pi Day.
What's Pi Day? Wikipedia informs us that "Pi Day is a holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day."
Larry Shaw, a physicist at the San Francisco Exploratorium, created Pi Day in 1988 where the holiday is observed every year. Here is how it's celebrated:
At 1:59 p.m. Saturday, a long parade of math enthusiasts will approach a small brass marker inside the San Francisco Exploratorium, circle clockwise around the monument precisely three and one-seventh times, and then sing "Happy Birthday" to Albert Einstein.
And of course, what's Pi Day without a little pie?
"It's a geek holiday," said co-organizer and Exploratorium physicist Ron Hipschman, who has hosted the museum's celebration since its inception in 1988.
The holiday is now celebrated in schools, on websites, and in groups from around the world with pi(e)-eating, pi-digit memorizing, pi songwriting, piems, and even the exchange of pi greeting cards.
If you're wondering what the heck is a piem, it's a poem constructed according to a form of writing called Pilish - where the number of letters of successive words is determined by pi.
I like pi. Here's something you might not have known. Hidden inside of pi is every article I have ever written since I started blogging in 2006. That is, convert every letter of every word of every article of mine into its ascii representation, then that long string of numbers will be found somewhere in pi. For example: The first sentence of this paragraph "I Like pi" when converted into ascii looks like this: 733210810510710132112105. I can tell you without any doubt in my heart that this sequence of numbers appears somewhere in pi although not in the first 200 million digits (see how to search for a sequence of numbers inside of pi here).
