March 14 is not just Albert Einstein's birthday. It's celebrated by many math fans and mathematicians as Pi Day. March 14, 3.14 — get it?
The more precision-minded speak of Pi Minute — 3/14, 1:59 — or even Pi Second — 3/14, 1:59:26. And in Europe, where the standard date format is the more logical day/month/year instead of month/day/year, they celebrate Pi Approximation Day on July 22 — that is, 22/7.
Celebrate Pi Day tonight with a pizza for dinner. Or maybe a slice of Dutch Apple for dessert.
