Today is Pi Day!
Pi Day was founded by Physicist Larry Shaw in 1988.
Pi Day is celebrated by math enthusiasts (read – lonely shut-ins) around the world on March 14th.
π was first used as a mathematical symbol in 1706 by William Jones.
Albert Einstein’s parents conveniently arranged for him to be born on Pi Day in 1879.
