On March 14, math and science lovers around the world celebrated a special day: Pi Day.

Pi is equal (平等的) to about 3.14, but the number is endless. It is sometimes written in Greek. With the help of computers, mathematicians have been able to work pi out to over a trillion (万亿) decimal (小数的) places, but there is still no end to the number. This makes pi confusing, even for the most famous scientists and mathematicians.

Pi Day is celebrated around the world on March 14, since how we write this date, 3/14, looks just like the number pi.

For some people, the attraction of Pi Day goes far beyond math and science. Pi shows up throughout popular culture. You can see it in movies, comics, music and more. “In modern movies, any time the filmmaker wants to evoke (唤起) a sense of mystery, often the symbol pi is used,” said David Blatner, a Jewish-American writer of The Joy of Pi.

People also love trying to memorize the digits (数字) of pi and competing against others to see who can remember the most. Many teachers hold class contests to see how many numbers their students can memorize. The Guinness World Record for reciting (背诵) the most digits of pi is held by Lyu Chao of China, who successfully recited pi out to nearly 67,890 decimal places.

Above all, Pi Day is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with fun pi-related games and activities. In 2016, Princeton, New Jersey, held a birthday party for Albert Einstein whose birthday also falls on March 14. There was also a “Walk a Pi Event” where people walked 3.14 miles together. Just like the number itself, the possibilities for Pi Day are truly endless.
