March 14 (written 3/14 in the United States) is known as Pi Day, a holiday that people ring in with pie eating contests, pizza parties, and math puns. If the most important number in mathematics wasn’t enough of a reason to reach for a slice of pie, March 14 also happens to be Albert Einstein’s birthday, the release anniversary of Linux kernel 1.0.0, and the day Eli Whitney patented the cotton gin. - -In honor of this special day, we’ve rounded up a dozen fun facts and interesting pi-related projects. Master you team’s Pi Day trivia, or borrow an idea or two for a team-building exercise. Do a project with a budding technologist. And let us know in the comments if you are doing anything unique to celebrate everyone’s favorite never-ending number. - -### Pi Day celebrations: - - * Today is the 30th anniversary of Pi Day. The first was held in 1988 in San Francisco at the Exploratorium by physicist Larry Shaw. “On [the first Pi Day][1], staff brought in fruit pies and a tea urn for the celebration. At 1:59 – the pi numbers that follow 3.14 – Shaw led a circular parade around the museum with his boombox blaring the digits of pi to the music of ‘Pomp and Circumstance.’” It wasn’t until 21 years later, March 2009, that Pi Day became an official national holiday in the U.S. - * Although it started in San Francisco, one of the biggest Pi Day celebrations can be found in Princeton. The town holds a [number of events][2] over the course of five days, including an Einstein look-alike contest, a pie-throwing event, and a pi recitation competition. Some of the activities even offer a cash prize of $314.15 for the winner. - * MIT Sloan School of Management (on Twitter as [@MITSloan][3]) is celebrating Pi Day with fun facts about pi – and pie. Follow along with the Twitter hashtag #PiVersusPie - - - -### Pi-related projects and activities: - - * If you want to keep your math skills sharpened, NASA Jet Propulsion Lab has posted a [new set of math problems][4] that illustrate how pi can be used to unlock the mysteries of space. This marks the fifth year of NASA’s Pi Day Challenge, geared toward students. - * There's no better way to get into the spirit of Pi Day than to take on a [Raspberry Pi][5] project. Whether you are looking for a project to do with your kids or with your team, there’s no shortage of ideas out there. Since its launch in 2012, millions of the basic computer boards have been sold. In fact, it’s the [third best-selling general purpose computer][6] of all time. Here are a few Raspberry Pi projects and activities that caught our eye: - * Grab an AIY (AI-Yourself) kit from Google. You can create a [voice-controlled digital assistant][7] or an [image-recognition device][8]. - * [Run Kubernetes][9] on a Raspberry Pi. - * Save Princess Peach by building a [retro gaming system][10]. - * Host a [Raspberry Jam][11] with your team. The Raspberry Pi Foundation has released a [Guidebook][12] to make hosting easy. According to the website, Raspberry Jams provide, “a support network for people of all ages in digital making. All around the world, like-minded people meet up to discuss and share their latest projects, give workshops, and chat about all things Pi.” - - - -### Other fun Pi facts: - - * The current [world record holder][13] for reciting pi is Suresh Kumar Sharma, who in October 2015 recited 70,030 digits. It took him 17 hours and 14 minutes to do so. However, the [unofficial record][14] goes to Akira Haraguchi, who claims he can recite up to 111,700 digits. - * And, there’s more to remember than ever before. In November 2016, R&D scientist Peter Trueb calculated 22,459,157,718,361 digits of pi – [9 trillion more digits][15] than the previous world record set in 2013. According to New Scientist, “The final file containing the 22 trillion digits of pi is nearly 9 terabytes in size. If printed out, it would fill a library of several million books containing a thousand pages each." - - - -Happy Pi Day! - -

+很荣幸，我门能在这一天一起了解有关它的有趣的事实和与π相关的活动。来吧，和你的团队一起庆祝圆周率日：找一两个点子来进行团队建设，用新兴技术做一个项目。如果你有庆祝为被大家所喜爱的无限小数的独特方式，请在评论区与大家分享。 + +### 圆周率日的庆祝方法： + + * 今天是圆周率日的第 30 次周年纪念。第一次为它庆祝是在旧金山的探索博物馆Exploratorium由物理学家Larry Shaw 举行。“在第 1 次周年纪念日当天，工作人员带来了水果派和茶壶来庆祝它。在 1 点 59 分，圆周率中紧接着 3.14，Shaw 在博物馆外领着队伍环馆一周。队伍中用扩音器播放着‘Pomp and Circumstance’。” 直到 21 年后，在 2009 年 3 月，圆周率正式成为了美国的法定假日。 + * 虽然它起源于旧金山，可规模最大的庆祝活动是在普林斯顿举行的，小镇举办了为期五天的[数字活动][2]，包括爱因斯坦模仿比赛、投掷派比赛，圆周率背诵比赛等等。其中的某些活动甚至会给获胜者提供高达 314.5 美元的奖金。 + * 麻省理工的斯隆管理学院MIT Sloan School of Management正在庆祝圆周率日。他们在 Twitter
