July 22, 2014 : Happy Pi Approximation Day!
My second favorite mathematical holiday is upon us… Pi Approximation Day!
Did you know, Babylonian mathematicians used 25/8 as an approximation for Pi in the early 19th century? Not only is this over 4 times less accurate compared with the 22/7, but it would have resulted in celebrating this holiday in August… preposterous.
