Happy Pi Day! This Year is a Rare, Epic One


For math lovers, a day like this only comes around once every 100 years.

Saturday will be a day for the math books, no matter which way you slice it.

For the first time in 100 years, Pi Day will fall on 3/14/15, matching up with the first five numbers that represent the ratio of a circle’s circumference to its diameter, 3.1415.

Going deeper, at 9:26:53 a.m. — and again at night — the day will represent the first 10 digits of the mathematical constant, bringing much merriment to members of the math community.

“It’s the Pi Day of the century,” said Michael Breen, public awareness officer at the American Mathematical Society, in Providence. “There’s a lot going on to celebrate.”

Tom Gaudette, principal academic evangelist at MathWorks in Natick, said pi reigns supreme among the mathematical constants.

“That’s because everybody has to learn about pi,” he said. “You don’t have to learn about the other constants. Everyone learns to calculate the circumference of a circle before graduating high school.”

That, and it’s a good excuse to eat baked goods, which also happen to be circular. “It’s humorous, it’s a lot of fun, and people obviously enjoy eating pie,” he said. “For me, next year won’t be as important.”
