14-15 March 20

Yesterday, 3-14 or 3.14 (Saturday), was Pi Day! So today I'm filling in with my π tie. In case you need a reminder, π is the irrational number that is best known as the ratio of a circle's circumference to its diameter. But it shows up all over statistics, physics, astronomy, music, acoustics -- it's one of the fundamental constants for virtually every repeating pattern we can observe, and so it is also very philosophical.
