Einstein Was Born On Pi Day-爱因斯坦诞生于圆周率日

 


Pi Day is celebrated 2 on March 14 (3.14), the closest calendar date to the mathematical number “pi”. Pi, named after a Greek letter (∏), is the ratio of a circle’s circumference divided by its diameter. While the exact value of pi is impossible to determine because it goes on indefinitely without making a pattern, it is typically written as 3.14. Some math and science enthusiasts 3 celebrate Pi Day with pie-eating contests, while others enjoy pizza (pie) parties! Pi Day originated at a museum in San Francisco in 1988. Coincidentally, March 14 is also Albert Einstein’s birthday. Einstein was a mathematician 4 and physicist 5 who became famous for his theory of relativity.
