I don't know how many people celebrate this, but today is Pi Day. Pi is a mathematical constant, with the first three numbers being three, one and four. Most people just celebrate by baking or eating pies. I made one for my daughter's math class.
Pi itself is actually very fascinating, though. It was originally defined as the ratio of a circle's circumference, but now it's used in many formulas in math and physics. Its decimal presentation never settles into a permanent repeating pattern.
But, ah... I'm sure most people just care about the pie.
