**Pi Day** is a holiday commemorating the mathematical constant π (pi). Pi Day is celebrated onMarch 14 (or 3/14 in *month/day* date format), since 3, 1 and 4 are the three most significant digitsof π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day because a lot of them are crusty and full of filling.

March 14 is also Albert Einstein’s birthday (no relation). Speaking of relations, after he divorced his first wife, he married his cousin. His main attraction to her was her cooking. By historical accounts, their marriage seems to have been pie-tonic.

THREE REASONS PI IS A PRETTY IMPORTANT NUMBER

1. It is the only mathematical constant you can name.

2. It calculates to an infinite number of decimal places without ever repeating a series of numbers.

3. It sounds an awful lot like “pie.”

THREE REASONS ALBERT EINSTEIN IS A PRETTY IMPORTANT GUY

1. He suggested during the Second World War that making an A-bomb might be a good idea since Adolf Hitler was doing it already.

2. He showed that energy and mass are equivalent and transmutable (E=mc2).

3. He invented space-time, whatever that is.
