Oh, that magical number! π (Pi) is the golden ratio (the ratio of a circumference of a circle to its diameter), a “transcendental number” (its numbers continue without pattern), which has been calculated out to ten trillion digits beyond its decimal point. Pi Day takes place on March 14 every year, which also happens to be Albert Einstein’s birthday. Whether your idea of a fun Pi Day involves virtually traveling back to the 16th century to study up on the history of the wondrous number itself, or if you just want to use it as an excuse to eat or make pie (lots of pie!) we will not judge you. Here is a smattering of ideas at DPL to help you have a delicious and educational Pie Day. Can’t make it out to an event? No problem! Here’s a list of Pi-related movies, and tons of other materials available from your library.
Saturday, March 11, 10 a.m.-4 p.m. @ Central, Children’s Library
