The uniqueness of Mathematical Date 11/11/11
Dated 11/11/11 is a moment that only happens once in a century. Many people consider this moment as something very special, including the mathematician. Last week, dated 02/11/2011 mathematics turned out to have other qualities that make it a date that only happens once in 10,000 years.
Aziz Inan, a professor of electrical engineering at the University of Portland, Oregon, said that when the date is expressed as a number, 11.022, 011, has very special properties. "It was the product of 7 squared times 11 times 13 square rank. Impressive as they are of three consecutive primes.
There is no other palindrome date of like that up to 10,000 AD," Inan said. "Not only that, if you write it as 72 x 113 x 132, you'll see the power superscript numbers, 232, is a palindrome." It may be difficult to match the above date, but also special 11/11/11.
Some people believe that the date 11/11/11 is a lucky day mystic or the date 11/11/11 is a good day to make money. Inan explained that when someone saw him up close, this date also has some interesting mathematical properties. 11/11/11 The next will happen 100 years from now, on 11 November 2111.
Interestingly, 11/11/11 followed by eight-digit palindrome day, 12/11/2111, which is quite appealing to fans of palindromes as Inan. Inan explained that if you consider the date 11/11/11 as number 111 111, then you can run a few extra tricks math fun.
111 111 can be obtained from its largest prime factor of numbers, 37: First, 73 [number opposite 37] minus 37, then you get the 36. [Inan added that 36 equal to the square of the number of digits 111 111].
Second, the number 36 can be constructed by three consecutive numbers: 11, 12 and 13. Then, multiply by 11, 13, 37 and 21 [the inverse of 12]. What comes out? 111 111.
