An Indian man with an incredible memory recently set a new world record by reciting 14,000 digits of Euler’s number in just 49 minutes.
最近，一名记忆力惊人的印度男子在49分钟内背诵了欧拉数的14000位，创造了一项新的世界纪录。
Deepu V has always had an incredible memory when it came to numbers. He once set a national record by reciting 2,000 digits of the irrational number (无理数) pi faster than anyone else, and claims to have committed 500 telephone numbers to memory. But when he heard about a world record for memorizing the most decimal (小数的) places of Euler’s number, he saw an opportunity to have his name featured in the Guinness Book of Records. He spent four months preparing for this attempt and took under an hour to blow the previous record of 10,122 digits right out of the water.
Deepu V在数字方面总是有惊人的记忆力。他曾以比任何人都快的速度背诵无理数圆周率的2000位数字，创造了一项全国纪录，并声称自己记住了500个电话号码。但当他听说有一项记住欧拉数小数点后位数最多的世界纪录时，他看到了一个让自己的名字出现在吉尼斯世界纪录册上的机会。他花了四个月的时间准备这次尝试，只用了不到一个小时就打破了之前10122位数字的记录。
Like pi, Euler’s number is an irrational number. It begins with 2.71828 and continues infinitely in a series of decimals that never repeat. To ensure that challengers don’t cheat during their attempts at breaking this unique Guinness Record, their ears are checked and they are blindfolded before they begin reciting digits. But Deepu was so confident in his method of memorization that he was unfazed by the strict rules of the record attempt.
和圆周率一样，欧拉数也是无理数。它从2.71828开始，以一系列永不重复的小数无限延伸。为了确保挑战者在打破这一独特的吉尼斯纪录的过程中不会作弊，在他们开始背诵数字之前，他们的耳朵会被检查，眼睛也会被蒙住。但Deepu V对自己的记忆方法非常有信心，所以他对挑战记录的严格规则毫不畏惧。
“In a table, there are 10 columns and 20 rows. I added five digits in each column, thus in a column of one full row, there are 50 numbers. And with 20 rows on a page, there will be a total of 1,000 digits. Likewise, in 14 pages I was able to include 14,000 digits,” the 33-year-old man told Guinness Records.
“在一个表中，有10列20行。我在每一列中加了5个数字，因此在一列中有50个数字。一页上有20行，总共有1000个数字。同样地，我在14页纸上写了14000个数字，”这位33岁的男子告诉吉尼斯纪录。
Deepu V spent four months preparing for his challenge. He memorized 250 digits per day from Monday to Thursday, using the remaining three days of the week consolidating all this new information in his memory. To ensure he was ready, he sometimes recorded himself reciting Euler’s number decimals to catch any mistakes he made.
Deepu V花了四个月的时间准备这次挑战。从周一到周四，他每天记住250个数字，用一周剩下的三天巩固所有这些新信息。为了确保他准备好了，他有时会录下自己背诵欧拉数字小数的过程，以便发现自己犯的任何错误。
All the hard work paid off, as in the end, Deepu V made short work of the previous Guinness Record of 10,122 recited Euler’s number decimals, reciting no less than 14,000 decimals in 49 minutes.
所有的努力都得到了回报，最终，Deepu V在49分钟内背诵了不少于14000个小数，一举打破了此前10122个欧拉数字小数的吉尼斯纪录。
