Pi Day Events in Boston, 2015

Celebrate with $3.14 pie slices, 3.14-mile road races, MIT pie fights, and more.

Considering how many smarty-pants types live here, it should come as no surprise that Boston embraces Pi Day with such gusto. Internationally, 3/14 is celebrated as the day bearing the same initial digits as pi, the irrational number representing the ratio of a circle’s circumference to its diameter, among other mathematical wonders. While the sequence is infinite, pi taken to its first seven decimal places is 3.1415926. That means that this year’s Pi Day is a once-in-a-lifetime event: For the first time in a century, we’ll be able to properly celebrate even more digits of pi than usual, thanks to its 3/14/15 date.

Here’s how to make the most out of a day in the life of pi.

Pi Day at MIT

In Cambridge, March 14 marks the day MIT announces its college admissions decisions. This year, in a burst of sheer pi exuberance, the school has abandoned its usual diplomatic nod to Tau Time, and will instead be releasing results at 9:26 a.m. In addition to the acceptance-letter frenzy, the Institute for Hacks, TomFoolery, and Pie will host its very own “Pi Day at Ashdown” festivities, featuring pi reciting, pie eating, and pie throwing. But would-be entarteurs take note: This particular pie fight is strictly for MIT students.

6-8 p.m., MIT, 77 Mass. Ave., 617-253-1000, events.mit.edu.

WPI Irrational Run

MIT isn’t the only campus getting in on the pi action, of course. In honor of its 150th birthday, Worcester Polytechnic Institute is hosting its first-ever Pi Day road race, which claims to span a distance of 3.1415926 miles. The race begins at 3/14/15 at 9 a.m., and (to complete the sequence) the first 26 runners to reach the finish line will receive “a special prize.”

9 a.m., WPI, 100 Institute Road, 508-831-5000, wpi.edu.

Pi(e) Day at Petsi Pies

It’s not enough that Petsi Pies dominates the competition when it comes to pie; these guys bring their A-game to Pi Day as well. For over a decade, they’ve been hosting an annual pi recitation challenge, which drew hundreds of math-minded dessert fans last year. If you think you’ve got the chops, head to their Beacon Street location, where you can compete for a free Cutie Pie (if you can recite 10 digits of pi), a free Large Pie (for 314 digits), or a free-pie-per-season gift card (for 628 digits). For those afraid their memory skills might cost them some precious pastry, don’t worry. “You can try as many times as you need to,” Petsi general manager Talbot Penniman assures us.

9:26 a.m., Petsi Pies, 285 Beacon St., 617-661-7437, petsipies.com.

$3.14 Pie at Beacon Hill Bistro and $3.14 Pizza at Salvatore’s

Pie for breakfast? Yes, please. Once again, Beacon Hill Bistro is bringing back their Pi Day special: During breakfast service, you can get a slice of pie for $3.14. But if your taste for circular treats falls on the savory side, make a beeline to Salvatore’s. They’re offering a $3.14 flatbread pizza, with options including margherita, rabe and bacon, and sweet chili chicken.

7:30-10 a.m., Beacon Hill Hotel & Bistro, 25 Charles St., 617-723-7575, beaconhillhotel.com.

12-5 p.m., Salvatore’s, multiple locations, salvatoresrestaurants.com.

Pie All Day at Ames Street Deli

If there’s anything better than pie for breakfast, it’s mandatory all-day pie. This Saturday, Kendall Square’s Ames Street Deli salutes 3/14 by serving up pie—and only pie—all day, with slices going for $3.14. They’ll offer at least eight different pies, including lobster pie, Dark and Stormy pie, and pear, fig, and bacon pie. And if that’s not quite bonkers enough for you, Ames Street co-owner Diana Kudayarova says, “Our usual Saturday pancakes will also appear in a pancake pie.” If you need something to wash that down with, try their apple pie cocktail (“à la mode, of course”). Alas, while pi is infinite, the pie-all-day special ends at closing time.

7 a.m.-12:30 a.m. next day, Ames Street Deli, 73 Ames St., 617-374-0701, amesstreetdeli.com.

Parπy Like It’s 3.14.15 9:26:53 at Cuisine en Locale

Cuisine en Locale, the catering company of personal chef extraordinaire JJ Gonson, is throwing their own Pi Day bash. According to Gonson—who claims to be a big fan of mandatory pie herself—this party is basically an excuse to eat lots of pie and meet locavores’ behind-the-scenes heroes: the farmers who supply their home-grown bounty to Cuisine en Locale. “For a long time, we’ve wanted a day where we say thank you to our farmers,” Gonson says. Mingle with farmers and enjoy live tunes while you dig into those sweet and savory pies. Admission is free; menu items are à la carte.

5 p.m., Cuisine en Locale, 156 Highland Ave., 617-285-0167, cuisineenlocale.com.

Pi Day Design Challenge at Museum of Science

Too much dessert and not enough pi, you say? First of all: There’s no such thing as too much dessert. Second: For the applied math purists out there, the Museum of Science has you covered, with a special engineering challenge. This weekend, they invite visitors to build a bobsled that can complete a lap around the track in 3.14 seconds. This activity, targeting kids in grades 4-10, is free with exhibit halls admission.

10:30 a.m.-12:30 p.m. and 1:30 p.m.-3:30 p.m., Museum of Science, 1 Science Park, 617-723-2500, mos.org.

Charles Hotel

The Charles—the same hotel that offers a year-round “Smarty Pants Package”—is having a Pi Day flash sale on March 13. For rooms booked for dates between March 14 and May 11, they’re discounting bookings by 31.4 percent. And at those prices, we’re not about to quibble with them about that dodgy decimal point placement.

Charles Hotel, One Bennett St., 617-864-1200, charleshotel.com.
