Happy Pi Day!
Pi is the relationship between a circle’s circumference and its diameter. Tau is the ratio of a circle’s circumference to its radius. Pi = 3.141592653.. Tau = 6.283185307.. It’s been argued that Tau is a better value to use, but today let’s just talk about Pi , since it’s Pi Day! This post is being published, and this website is being launched, on 3/14/15 at 9:26 and 53 seconds, mountain time. Pi = 3/14/15-9:26:53… Technically it is Gregorian Pi Day, since our months are all screwed up. In the 16th century Pope Gregory, in his infinite wisdom, decided to change their order. This is easy to see since the etymology of half of the months clearly indicates this. January is the first month but this wasn’t always so. March is actually the first month of the year which makes sense as Earth renews itself…
