Pi Day is a big deal for NASA’s Jet Propulsion Laboratory, but for many of us it just means big deals.
Pi Day falls on Thursday, March 14 this year.
The holiday pays tribute to Pi, a Greek letter and what mathematicians call the ratio of a circle’s circumference to its diameter. Its first three digits are 3.14.
Pi was first applied to the third month, 14th day of the year by a physicist at the San Francisco Exploratorium in 1988, according to NASA. U.S. Congress declared March 14 National Pi Day in 2009.
Pasadena’s JPL considers Pi Day to be filled with teachable moments and issues math students an annual challenge using the constant. This year’s mathematical problem involves a 15-second video of a cat chasing a laser that was beamed to Earth from deep space in December. Students are asked to calculate how NASA aimed the transmission.
Now for the delectable moments of Pi Day.
Many restaurants that sell circular foods, usually pizza parlors, have used the holiday as a promotion, often involving the price $3.14. Some restaurants that sell fruit pies also get into the act.
Here are some chains that have announced Pi Day deals this year in news releases, on their websites or in social media. Some of them require memberships, and there are usually limits and restrictions. Check the details before you commit.
