It's π Day! The irrational number π has a decimal value that starts 3.14159.... and so the 14th day of the 3rd month is a time for special celebrations. Pi equals the ratio of a circle's circumference to its diameter. My tie celebrates cherry pie.
Two birthdays noted on my genealogical calendar: my great-great-grandfather (on my father's side) David Dreibelbis (1792-1886) was born on March 14 in Richmond, PA, and my great-grandfather (on my mother's side) Royal George Kinner (1843-1900) was born on March 13 in Cato, NY. March 14 is also the birthday of Albert Einstein (1879-1955), and marks the date in 1912 when the name Oreo was trademarked for that cookie.
