Today is National Pi Day. As in the ratio of a circle’s circumference to its diameter. As in the area of a circle is Pi times the radius squared. (Sorry, I cannot type symbols on my iPhone).
I don’t know whether to be happy that I can still remember a bit of pi’s value of 3.1415 — or am depressed because when I was younger I could carry it out to at least 10 digits (3.1415926535, yes I had to look it up).
Update. Ended up with peach/huckleberry pie. Yummm.
