People Celebrate 'Pi Day' in Different Ways
This is What's Trending Today...
March 14 is known around the world as "Pi Day."
"Pi" is something you may remember from math class. It is the number that results when the distance around a circle is divided by the distance across the circle. It is a very important number in geometry as well as for fields like construction and architecture.
Pi is an irrational number. It never ends. But the way it begins is always this: 3.14159. The date March 14, as we write it in the United States, is 3-14.
American physicist Larry Shaw started Pi Day back in 1988.
The hashtag #PiDay was the top trending topic on Twitter Tuesday. Pi Day is not just for those who enjoy numbers. Many people mark the math-inspired holiday by celebrating "pie," -- p-i-e, instead of "Pi."
Pie is a popular dessert in the United States. It is made with a crust on the outside and usually a sweet filling in the middle. Apple pie, pecan pie, and cherry pie are among the best known.
Pizza is another kind of pie. It is made with a crust, tomato sauce, cheese and other toppings. One pizza restaurant is celebrating Pi Day in a big way. The restaurant &pizza is letting customers get married at its locations in several East Coast cities.
While Pi Day is usually a light-hearted event, thousands of technology workers in California's Silicon Valley are marking it in a more serious way this year. They are walking out of their workplaces at Apple, Facebook and Google to protest U.S. President Donald Trump's policies on immigration.
Among those policies is Trump's travel ban, which blocks the approval of U.S. visas to citizens of six Muslim-majority countries and bars refugees from entering the country.
Top executives and workers in Silicon Valley have been sharply critical of the ban. Many technology companies there were started by immigrants or children of immigrants.

你可能在数学课上接触过“Pi”（圆周率） 。圆周率是圆的周长与直径的比值 。圆周率是几何学以及建筑学领域很重要的一个数字 。
圆周率是一个无理数 。即无限不循环小数 。圆周率的开头为3.14159 。而圆周率日正是由近似值3.14得来 。
1988年，美国物理学家拉里·肖（Larry Shaw）最先庆祝圆周率日 。
周二“圆周率日”成为推特上的热门话题 。圆周率日不仅是为热爱数字的人而设立的 。很多人借“派”（pie）来庆祝这个特殊的数学节日 。注意是Pie，而不是Pi 。
派是一款深受美国人青睐的点心 。点心外层包裹着结实的面皮，内含甜味夹心 。其中耳熟能详的有苹果派、山核桃派、樱桃派 。
披萨也是派的一种 。披萨由硬面皮、番茄酱、芝士和其他馅料制作而成 。有一家披萨店用盛大的形式欢庆圆周率日 。这家披萨店允许新人在美国东海岸几大城市的分店内举行婚礼 。
虽然圆周率日看似是个轻松的节日，然而加州硅谷有成千上万名技术人员用更加严肃的方式庆祝今年的节日 。他们走出苹果、脸书和谷歌的办公大楼，抗议美国总统唐纳德·特朗普（Donald Trump）的移民政策 。
硅谷各公司的高层与员工一直强烈反对这一禁令 。硅谷有很多科技公司都是由移民或移民后代创办的 。
