PI DAY & LIGHT – today is Pi day (3.14) and also Albert Einstein‘s birthday.
About PI Day:
Pi Day is a holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.
