Ramanujan's Deathbed Conjecture Finally Proven

jomama717 writes "Another chapter in the fascinating life of Srinivasa Ramanujan appears to be complete: 'While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right. "We've solved the problems from his last mysterious letters. For people who work in this area of math, the problem has been open for 90 years," Emory University mathematician Ken Ono said. Ramanujan, a self-taught mathematician born in a rural village in South India, spent so much time thinking about math that he flunked out of college in India twice, Ono said.'"

      Actually, there are some universities that penalize you for going beyond a certain number of credits when working toward your BA/BS (if I remember correctly, Univesity of Texas at Austin is one of them, but my memory might be failing me). Which would prevent someone (outside of double majoring) from taking too many courses outside their area of specialization (major).

      That said, as someone who has recently (within the last two years) started working on their college degree(s) part time while maintaining a career, I've found my opinion of liberal arts style education changing rapidly. I originally wanted to major in Physics, I still do, but the current phase of my career doesn't allow me to attend a school that offers a degree in Physics (both due to schedule and location). However I am able to pursue a degree in Mathematics on-line. When I first attempted the Physics degree many years ago, I wasn't looking forward to the general classes and wanted to just jump in and do only Physics and Math, maybe some related courses (Engineering, Chemistry, etc). I hated my English and social science classes.

      Fast forward roughly a decade, now I'm working full time in a decent career and finding that those general classes I'm required to take actually have value and can be directly applied to my career as I take them. Psychology and English help with the management aspects of my job, Mathematics with the technical, History with the perspective, etc.

      While specialization is certainly important in many fields, that doesn't mean a general education isn't important. English has helped me understand what I'm reading as well as write documentation, training materials and performance evaluations. Psychology has given me tools to work with both my seniors and subordinates and made me a more effective manager. Economics has given me a better idea of how our economy actually works and given me the ability to better judge (though not perfectly) politicians and their policies. What I've gained from Mathematics (through multi-variable calculus and soon linear algebra and diff eq.) and Statistics probably doesn't need to be echoed on slashdot.

      10 years ago, I would have been pissed I had to take some of these classes. Now, even without the piece of paper, I've already strengthened my career and pushed past many of my peers. Where I started out just looking to do Math, and still enjoying my Math classes quite a bit, I'm now looking forward to my next English class. Hell, I even found a valid use for literary analysis the other day outside of pure intellectual wankery.

    Ramanujan was brilliant at mathematics, and there is no denying that. But like any school/college, his was made for the average person. Sure, it would be great if education was tailored to each individual's aptitude. But we don't have a good way of finding out what that is directly yet. Instead, we throw a bunch of subjects at students, and they figure out where there relative strengths are. And they focus on one or two areas where their natural aptitude lies (or more realistically, where their job prospects and abilities/interests combine to give "best" results; best being chosen by the student. Some may chase money, others fame, others just want to solve interesting problems - applications/paycheck be damned).

    And discovering outliers early is hard when the teachers themselves are not much better at their subjects than the students. If some kindergarten student started using calculus for loading of building blocks, it won't be much use if her teacher doesn't realize that what she is doing is phenomenal (especially since the child will have her own notations/symbols). Obviously, that is an extreme example, but the point remains - outliers will have a tough time in the current system.

    Alternatively, we can let everyone do what they find interesting, but a majority of students will just spend time doing "fun" things like sports - which is not necessarily bad. But as long as we have the current system where you starve if you can't hold down a job doing "productive things", I think the educational system prepares most people for such a world.

    Outliers are great - and can help speed up society's progress significantly. But at the end of the day, they are just that - outliers. If you design a system to help the outliers, most people (myself included) would wind up getting a very bad outcome - because most people aren't phenomenally skilled at anything (and no, being the best me I can be doesn't cut it). And if you have a lot of starving deadbeats on the street (instead of the mediocre, but holding down a job majority) I expect society to completely break down - and that won't help the outliers either.

There is a house in between (x) such that the sum of the house numbers to left of it equals the sum of the house numbers to its right. If n is between 50 and 500, what are n and x?" This is a bivariate problem with multiple solutions. Ramanujan thought about it and gave the answer with a twist: He gave a continued fraction. The unusual part was that it was the solution to the whole class of problems. Mahalanobis was astounded and asked how he did it. "It is simple. The minute I heard the problem, I knew that the answer was a continued fraction. Which continued fraction, I asked myself. Then the answer came to my mind," Ramanujan replied.
