A Pi Day for the Ages
On Saturday, 3/14/15, at 9:26:53am, the clock aligned to represent the first 10 digits of pi: 3.141592653.
That won't happen again until a hundred years from now.
Some celebrated the famous irrational numberthe ratio of the circumference of a circle to its diameterwith a day's worth of events at the Exploratorium in San Francisco (which founded the celebration of Pi Day in 1988) and others by, well, eating some pie.
Still others celebrated in conjunction with Albert Einstein's birthday, which was also March 14.
Here's a roundup of noteworthy Pi Day tweets:
