March 14th is the birthday of Albert Einstein, born in Ulm, Germany, 1879.
It is also Pi Day!
Pi is calculated as the circumference of a circle, divided by its diameter – which is always the same, irrational number!
The first three digits of pi coincide with the U.S. mm-dd-yy date format of 3/14, giving us Pi Day.
Why not celebrate with a circle-themed word search?
