20世纪世界著名数学家诺伯特·维纳很年轻就成为美国哈佛大学的科学博士,在博士学位的授予仪式上,执行主席饶有兴致地询问他的年龄。维纳巧妙地回答:“我今年岁数的立方是个四位数,岁数的四次方是个六位数,这两个数,刚好把十个数字0、1、2、3、4、5、6、7、8、9全都用上了,而且既不重复又不遗漏。这意味着全体数字都得向我俯首称臣,预祝我将来必定在数学领域里干出一番惊天动地的大事业。” The 20th century world-renowned mathematician Norbert Wiener became a young Ph.D. candidate at Harvard University in the United States. At the ceremony for awarding a doctorate, the Executive Chairman asked with great interest his age. Wiener cleverly replied: “I am a four-digit cube of the age of this year, the fourth power of the age is a six-digit number, these two numbers, just ten numbers 0,1,2,3,4,5, 6, 7, 8, 9 all are used, and they are neither repetitive nor omissible, which means that all figures have to bow to me and wish me a certain earth-shattering career in the field of mathematics. ”
