Today is a special Pi day (3/14). At 9:26am, between 53 and 54 seconds, the calendar will exactly read 3/14/15 9:26:53…. It is a once-in-a-century moment because the last two digits of the year spells out the next two parts of the infinite number. Add in the hour, minutes and seconds and you have an even longer start: 3.141592653. Kind of cool. Extremely nerdy.
