A few of you may be wondering, “What IS pi?” Rather than force you to dust off those brain cells that have atrophied since graduating college, pi is the ratio of the circumference to the diameter of a circle; approximately equal to 3.14159265358979323846264338327950288419716… the numbers following the decimal go off into infinity, so pi is usually simply rounded to 3.14. Hence, every March 14 (3/14) is National Pi Day. Google’s homepage logo illustrates some of the formulas that need pi.
The symbol for pi is of Greek origin and looks like this: Π
From Detroit Free Press, Today is Pi Day!:
Today is Pi Day, which is celebrated each year on March 14.
Pi, approximately 3.14159, is the mathematical constant that represents the relationship between a circle’s diameter and circumference.
Google is marking the holiday today with a Google doodle that shows some of the many formulas that depend on pi.
For Pi Day, today only, with any entrée purchase, you can get a free slice of pie at Marie Callender’s… other vendors are offering discounts on slices of pie or whole pie, including Whole Foods, Petsi Pies, and Morton’s Steakhouse.
It also just happens to be Albert Einstein’s birthday today… how coincidental is that?
A mnemonic (memory trick) for the first 15 digits of pi (count the letters in each word) is “How I like a drink, alcoholic of course, after the heavy lectures involving quantum mechanics.”
From Gouverneur Times, SUNY Potsdam to Celebrate Pi Day:
SUNY Potsdam’s Math Alliance will host its annual Pi Day on Saturday, March 20, from 1 p.m. to 5 p.m. in Kellas Hall Room 106. The event will feature free pie, games, face painting, and other fun activities, such as “Pie a Professor in the Face.”
“The Pi Day celebration is a unique opportunity to explore the culture of mathematics,” said Dr. Blair Madore, associate professor of mathematics. “From finding your birthday in the digits of Pi, to learning why Pi is transcendental, to getting a Pi tattoo, or just eating some pie, it’s an opportunity for good family fun that is thoughtful and entertaining.”
From The LAist: Happy Pi Day!:
The first Pi Day celebration was held at the San Francisco Exploratorium in 1988, with staff and public marching around one of its circular spaces, and then consuming fruit pies; the museum has since added pizza pies to its Pi Day menu.
