Pi for geezers

Fun with numbersThe numerical value of pi has baffled scientists and mathematicians for many years. Pi is the ratio of a circle's circumference to its diameter. For most calculations, the numerical value has been assigned as approximately 3.14. Scientists and mathematicians have used computers and algorithms to calculate millions of digits beyond the decimal point.Eighty-year-old Oscar Dorr of Punta Gorda thinks back to earlier times in mathematic history, eons before he taught Navy students the physiology of aircraft systems. He's been a member of Mensa for more than 35 years and working with numbers since he was no more than single digits old.He said, "You know, I remember when math was simple.
