Classic Math Puzzle Cracked

An anonymous reader writes "This is cool - if mind-bending. A century ago, a self-taught math genius from India noticed some patterns in how numbers can be created by adding other numbers. Now a grad student has finished the job showing that the patterns apply to all prime numbers, not just some. There's more on the Indian math guy here."

    yeah, I saw that too. Like, how if you have a 4, and add a 1, you get a 5. It's pretty cool.

    I'm surprised we got as much detail! Should be something like "Some smart guy from a long time ago did some smart things, and now some other smart guy made them better..." Duuuuuh, that's what *I* got my degree for!

  13. True story (I may post it again sometime) by QMO · · Score: 3, Funny

    As a math graduate student student I was invited to watch the presentations of the people applying for a graduate faculty position at the university. I was only able to make it to one of the presentations, but it was an unforgetable experience for me.

    The applicant gave a very interesting presentation. I got lost during the first 5 minutes when he was still giving background, but it was still interesting. His presentation was on - assuming that I remember any of the very little that I may have understood - some specific behaviors of the infinite boundaries of n-dimensional manifolds.

    The best part was when he said, "In case you think that this is just esoteric and 'out there,' I want you to know that this stuff has real applications in topology."

    There were about 6 other grad students and 15 math faculty there and I think I was the only one to notice how funny that was, so I'm sorry if you don't get the joke.

    GH Hardy (he wrote A Mathematician's Apology) speaking of Ramanujan:

    I remember once going to see him when he was lying ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways."

    (London 1940).


    A funny co-incidence happened about 10 years ago that brought this story to mind when I moved back from A2 to Detroit. Our new phone number ended in 1729. Of course my GF complained that it would be hard to remember since it was such an un-interesting phone number!

    This will in turn reduce productivity in India so much that America becomes competitive again! Brilliant!
