“Perfect numbers like perfect men are very rare.”–Rene Descartes
“It’s clearly a budget. It’s got a lot of numbers in it.”–George W. Bush
Cherry is good, too.
It seems that perfect presidents are even rarer than perfect men or perfect numbers. And that goes doubly for perfect web sites, as that “W” quote above came from the inaptly named brainyquote.com. So what better entity to dedicate a day to than the most famous of imperfect numbers, π. On this Pi Day of the century (3/14/16 rounded up from 3/14/15) have yourself a slice of your favorite.

Actually, there are such things as perfect numbers and imperfect ones. A perfect number is the sum of all its proper divisors (excluding itself). 6 is the smallest, being the sum of 1, 2 and 3. The next is 28 which is the sum of 1, 2, 4, 7 and 14. Calling pi imperfect is a slip of the mathematical tongue. But, carry on, Mark, Pi Day is a red-letter day on MY calendar and I wore my Pi t-shirt to commemorate.
