        It does just seemed to me as if the point'd been made gratuitously, though. Associate Prof (his current job status in the field: it would've be much more interesting if the breakthrough had come from a full Prof, or a grad student) and University of Utah (if you were interested in following up on it) seems to be more relevant than the country he was born in.

          Yes, it's just you.

          The phrase you find so objectionable is *the first paragraph* of the the linked article in The Hindu, written by one " T. Jayaraman".

          "MUMBAI: An Indian mathematician, Chandrashekhar Khare, is poised to make a significant breakthrough in the field of number theory: with his solution of part of a major outstanding problem in algebraic number theory."

          http://www.hindu.com/2005/04/25/stories/20050425 06 530100.htm

          One suspects that The Hindu wrote it that way because The Hindu takes a special interest in Indians around the world and their achievements -- does this make them racists?

          Only to you.

          Uh... every textbook I've ever read refer to them that way, until the author of the textbook assumes that you know them and their history already.

      It's extra information about the guy that made the breakthrough. It explains why the article that describes the achievement is The Hindu - an Indian newspaper. Obviously you are trying to make a not-so-subtle 'it's racist' comment.

      Maybe it's not, but then neither is the fact that he's an associate professor at the Mathematics Department of the University of Utah.

      It's pretty common to mention where people are from when giving a news story. It's part of the human interest.

            That said, I kind of know where you're coming from. The world of media is such a fastpaced world that they dare not sit on a story for fear of being "scooped" by opposition. From their perspective, if this guy flops, they quietly drop the story and no one will remember them. On

        • A rigorous proof of a theorem will never fall apart unless the basic axioms of logic fall apart. A proof is basically saying "assuming these things, this must be true."

          The application (the "theory" part) may fall apart, but once proved, the theorem will essentially last forever. That's one of the draws of mathematics.

      Somebody mod the parent '-1 Misleading'. There are two problems commonly known as the "Serre conjecture", and the parent happens to point to the wrong one. This problem has very little to do with number theory.

      It's probably best to refer to the conjecture that is on the verge of being solved as "Serre's reciprocity conjecture".

      The other conjecture was solved in 1976, and ought to be called "The Quillen-Suslin Theorem", except that that also could refer to another related but different result.

    Just to speculate on a possible "what use" question that might arise, I can't help but notice the line This is one of the central themes of modern research in number theory and is devoted to the study of the relation between the symmetries of number theory and geometry. . If I may be so bold, anything that ties the study of pure math to geometry probably has implications for quantum mechanics. These objects may lie embedded in higher dimensions, and probably settle into stable configurations from near infinite possibilities. But they still have to satisfy some allowable mathematical model. This is just the type of thing that may allow us to better predict what those allowable states could be.

    This site does not have a very good record with mathematical breakthroughs that it runs on the front page. Just to give some examples:

    1) A year and a half ago Slashdot ran a story [slashdot.org] (along with most of the MSM) about a Swedish girl having solved the 16th Hilbert problem. That turned out to be a completely bogus claim - she had, in fact, proved nothing.

    2) Slashdot ran with there being infinitely many twin primes [slashdot.org]. The proof was flawed.

    3) No, the Riemann hypothesis [slashdot.org] (the most coveted result in all of Mathematics) has not been proved.

    Those are just the examples I can remember off hand. There have been several more, and I cannot think of a single one that has turned out to actually be true. So please take vague stories about being "poised to make a great story" from local press with a pretty hefty grain of salt...

    Glancing over the responses so far, I've come across several links to "the" Serre conjecture. Of course, since this is Slashdot (Land of the Karma Whore) it also looks like not a one of those referred to the conjecture relevant to this discussion.

    The particular conjecture of Serre that matters here focuses on the two-dimensional representations over a finite field of the Galois group Gal(Qbar/Q). Now since that's not particularly illuminating, let me say a bit more...

    First, Qbar denotes the algebraic completion of the rational numbers -- that is, all the stuff you need to add to the rationals so that you can do stuff like factor polynomials with rational coefficients. So things like sqrt(2) are in Qbar, but transcental numbers like pi aren't.

    Gal(Qbar/Q) is the group of symmetries of Qbar over Q -- the ways you can map it to itself while still preserving multiplication and addition, and leaving the rational numbers inside Qbar alone. For instance, complex conjugation gives an element of the Galois group.

    Now one way to understand any group of symmetries is by looking at its "linear representations" -- basically, ways of assigning matrices to each of the symmetries so that matrix multiplication matches up with the composition of symmetries.

    The conjecture talked about here claims to describe (in some sense) all such (irreducible) representations of Gal(Qbar/Q), at least if you limit yourself to 2x2 matrices and coefficients in a finite field.

    This is similar to the Langlands Correspondence, which (among other things) deals with representations of Gal(Qbar/Q) by complex matrices (though not just 2x2).

The biggest mistake you can make is to believe that you are working for someone else.

Working...
