  5. Re:What's really going on here on A Step Towards Proving the Riemann Hypothesis · · Score: 2, Insightful

    In short, this is an important advance in automorphic forms, but it is so technical that it doesn't belong on SlashDot.

    You do not really understand something unless you can explain it to your grandmother. -- A. Einstein.

    Lucky for us, my grandma doesn't read slashdot. But in a long-ago life, I earned a minor degree in math and took much more math en route to a degree in physics (undergrad and grad... but nowhere near this Riemann space stuff). So, I am both curious and competent. And I regret to say you didn't do the best job explaining the topic.

    Rather than just bitch... here's where I wish you'd explain more:
    • give (my grandma) an analogy for a membrane,
    • What are subtle number-theoretic symmetries? Again, handwavy analogies (for me and my grandma) are fine.
    • Is there a linkage or relationship between modes and frequencies, akin to physics standing wave equations?
    • Any pictures you can link to that visualize these in 2-space or 3-space in a way that makes us get a hint of a grasp of 5-space?
    • Ditto for the symmetries of 2-dim membranes: pics, examples, analogies?
    • What's this something and why did Gelbart-Jacquet lift it?
    • What's a native mode?... oh, wait, you did this one: a native mode is one that doesn't look like it merely adds a dimension (of complexity?) by doing something minor to alter a 2d or 3d or 4d case. What exactly would that something be? Is an ok analogy taking a bessel function in 2 or 3d, then adding a 1-d unrelated critter in to the 4th dimension that doesn't add any value that affects the other 3?
    • So, once I have this 5-d rippling thing that isn't some lazy mashup of a 2d and a 3d or any other easy simplification, are we ready to take on 'to each such mode of vibration there is an associated L-function?
    • What's automorphic? Messes with itself, literally, but... ?
    • If it is numerically computed, WHY? Why can't it be solved symbolically? Is this like PDE's or n-body problems, where the problem isn't mathematically solvable but we can get close to the answer via discarding nth terms in series, perturbations, approximations, or the likes?
    • While I agree that numerical solutions aren't purely 'right' like symbolic proofs, one can use them to do disproofs: if one shows that the error is less than E(x), and that numerical plus error's limit won't ever reach some condition, or that E(x) diverges, or whatever... that's useful and may be a step toward proving the Riemann Hypothesis. Granted, any time a tech journalist (including the slashdot editors) writes a headline, the baby jesus stabs a scientist's voodoo-doll with a long needle...
    • And what the hell is GRH? General/global/great/ Riemann Hypothesis?

    Thanks. Deconstructing this, I now have a (probably WRONG) sense for what you tried to say:

    These guys did some computational/numerical work that doesn't really go THAT far to proving the Riemann Hypothesis. They found some 5-d examples that were really 5-d complex (not just stunts to extend 2d, 3d or 4d without the additional dimension of complexity), they did numerical work to find some 'native' 5d modes (insert a better definition of mode than 'a solution set that is like a stable solution or a standing wave or whatever'). So, we now have computationally-done 5d hints, but we're no closer to symbolically solving 5d equations. It's a bit of computational insight, but it isn't a pure proof.

    Um, how did I do?

    I'm not sure why people like to trot out the 6,000 year old theory every time someone mentions the age of the Universe. Perhaps it is because they're seeking an opportunity to tar the faiths of the world with the brush of ignorance. [mumble mumble] ignorance of religion [mumble mumble] all believers [mumble mumble] getting [mumble] old [mumble] pedantic.

    Or perhaps we're getting tired of this (admittedly small) number of vocal, pedantic fsckwits telling us that the universe is only 6000 years old. And that these people keep trying to push that insanity into widespread acceptance.

    Don't tell me there aren't otherwise-sane-looking zealots wandering among us. Don't tell me they aren't DAMN vocal about this 6000-year-old claim being truth. I've recently shared an office with one, and met several in the last few years.

    Pick a state that has a cliched religiosity and spend time and you can meet a few, too. And then... try to dissuade them. Best bring your 'A' game, low expectations and some waders, though. You'll start on cosmological timelines, swerve to arguing carbon dating's fallibility, swerve to arguing steady-state radiation and radiodecay, struggle to explain doppler shifts in light and RF and sound and how they can be used to measure cosmic aging, flail as you ask 'but why would god create a universe already 25B light-years across and with light already en route and an earth with all these layers and fossils embedded -- is it just to keep us distracted?' Often, you'll find that cosmological aging is being resisted because evolution is wrong. Seriously. I know it's a non-sequiter, but there you have it. In general, expect the debate to swerve viciously and expect to be unable to stick to one topic until resolved. These are believers unwilling to unbelieve, not logicians seeking fundamental truth. And let's face it: nobody is naturally good at logic, and few adults are competent at careful, reasoned debate. Swerving and craptabulistic logical skills are gonna complicate your job immensely.

    I understand your frustration. Mocking believers of a 6000-year-old universe seems cruel, but the people these zealots might trust (other religious people, whether they are muslims, christians, jews, mormons, catholics, or whatever) aren't telling them to STFU, so we're left to repeatedly endure the BS or risk being called godless as we try to do somebody else's job.

    Personally, I can't think of a single club, sect, profession, or hobby where adherents don't consider themselves modestly responsible to act as guardians of the reputation of their peer group. As an untrusted outsider, it shouldn't be *MY* job to tell these guys to STFU because they're making and by extension all other religions look bad. Put another way, dentists police themselves because a bad dentist makes them all look bad. All us nondentists expect to trust that experts in dentistry and nearby fields (biologists, vets, MD's, whatever) will let us know if a sizeable bloc of dentists starts acting/believing stuff that violates science, or holding views that seem hazardous, damaging to the profession, or unethical.

    But for some reason, religious people (possibly you fall into this crowd) aren't doing their duty as theological peers to make these science-denying zealots accept that their faith needn't feel threatened, reminding them that the evidence passes muster, and that they need to adapt their rhetoric so that their religion isn't hideously incompatible with hard science and all the evidence showing timelines where t(now)-t(0) >> 6000y.

    I've tried arguing, gentle questioning in the style of Socrates, and just plain ignoring supporters of this crap. None work. And in the end, the cliche about teaching a pig to sing comes to mind: 'don't do it. It wastes your time and annoys the pig'.

    Snickering and mockery at least are gratifying. Sucks, but there you have it.
