20. March 14: Pi Day
Don’t let the sound of the name fool you: 3/14 does not commemorate the sweet, baked circuitous treat (but feel free to grab a slice). It is the official day of the Greek letter symbolizing the ratio of the circumference of a circle to its diameter, pi, also known as 3.14159265359 …
