世界节假日博览 第47期:圆周率日
时间：2018-12-29 作者：英语课 分类：世界节假日博览
Pi Day is on March 14. This is the day when mathematicians 2 and geometry enthusiasts 3 around the world get together and celebrate the mathematical constant of Pi. There are two good reasons to hold Pi Day on March 14. The first is that in the American date format 4, it is 3/14 and Pi, to two decimal places, is 3.14. The other reason is that March 14 is Albert Einstein’s birthday, and he knew a thing or two about numbers. Pi Day started in 1988 at the San Francisco Exploratorium. The museum staff walked around the circular spaces in the building eating fruit pies. Cherry and apple pies have very little to do with Pi, unless you want to calculate the circumference 5 of your fruity treat.
圆周率日会在每年的3月14日庆祝。这一天，全球的数学家和几何学爱好者会聚集在一起，庆祝数学常数“pi”。在这一天来庆祝该节日有两个原因。第一，在美国日期格式中，3月14日，pi小数点后两位正好是3.14。第二，3月14日也是爱因斯坦的诞辰，他对数字有着深入的了解。1988年，在旧金山科学博物馆举办了第一届圆周率日。博物馆工作人员在馆内作圆周运动，边做边吃水果派。樱桃派和苹果派与圆周率无关，除非你想算一算你水果大餐的周长。
Pi is a letter of the Greek alphabet. The symbol was first used in mathematical calculations in 1737 by the Swiss mathematician 1 Leonhard Euler. It is used for the ratio of the circumference of a circle to its diameter. Computers have calculated Pi to over one trillion digits 6. It has countless 7 numbers of digits. Perhaps more impressive is the feat 8 of British autism sufferer Daniel Tammet. He holds the European record for reciting Pi from memory to 22,514 digits in just over five hours. He also suffers from a condition in which he sees numbers as colours. He says Pi is particularly beautiful. The worlds of science, engineering and mathematics would be lost without it. Celebrate today with your favourite pie!
pi是希腊字母。1737年，瑞士数学家莱昂哈德·欧拉首次将它运用于数学运算。pi代表着圆周到直径的比例。计算机算出pi圆周率小数点后有1万多亿。pi的数值是无穷无尽的。或许，最让人印象深刻的就是英国自闭症天才丹尼尔·塔梅。他能够在短短5个小时之内记忆小数点后2万2514个数字，而这也保持着欧洲记录。他把数字看成是颜色。他认为圆周率特别美丽。如果没有它，科学界、建筑界以及数学界将不复存在。吃着你喜欢的“派”来庆祝吧。
