On this day in 1988, Larry Shaw, a physicist at the San Francisco Exploratorium, led the first observance of Pi Day with staff and public marching around one of its circular spaces, then consuming fruit pies. The now annual celebration commemorating the mathematical constant π (pi) is observed on March 14 (or 3/14 in the U.S.) since 3, 1, and 4 are the three most significant digits of π in the decimal form.
Frances Boltz Woodward, made this Mathematical Star quilt around 1840 in Virginia. The hand pieced, appliqued and quilted piece is now in the permanent collection of the DAR Museum.
