The Riemann Hypothesis

  • The Riemann Hypothesis is one of the Millennium Prize Problems and has something to do with primes. What's that all about? Rather than another hand-wavy explanation, I've tried to put in some details here. Some grown-up maths follows.
    More information: www.claymath.or...
    -----------------
    CORRECTION: The functional form of the zeta function is a reflection around the point 0.5, not the line x=0.5. But you can think of that as a reflection in the x-axis followed by a reflection in the line x=0.5.
    For example, if we start with zeta(x + iy) and reflect it in the x-axis we get zeta(x - iy). Reflect that in the x=1/2 line we get (junk)*zeta(1 - x - iy). And reflect that in the x-axis again we get (junk)*zeta(1 - x + iy). When zeta(x + iy) = 0 so are all the others.
    The zeros then look like this en.wikipedia.or... That's four zeros for the price of one.
    The zeros are still symmetric around the x=1/2 line. The reflection of zeta(x + iy) is (junk)*zeta(1 - x + iy). In the video I mixed up zeta(1 - x + iy) with zeta(1 - x - iy).
    But the point is the same, the error in the Prime Number Theorem is minimised if all the zeros lie on the line x=1/2.
    ---------------------
    Some people have asked about my final claim that you don't get the prize for a counterexample. Here is the rule from the Clay Institute:
    "if a counterexample is proposed, the SAB will consider this counterexample after publication and the same two-year waiting period as for a proposed solution will apply. If, in the opinion of the SAB, the counterexample effectively resolves the problem then the SAB may recommend the award of the Prize. If the counterexample shows that the original problem survives after reformulation or elimination of some special case, then the SAB may recommend that a small prize be awarded to the author. The money for this prize will not be taken from the Millennium Prize Problem fund, but from other CMI funds."
    In other words, there are no guarantees either way.

      @supadox Because often, the proof is rather easy to make if you did understand exactly the proofs and methods the textbook used to prove some other thing just before.
      And it is actually a good excercise to come up with ones own proofs. Though it is extremely hard i think.

    This is a great explanation of the Riemann hypothesis. I like how you presented it in historical context, broke it down into parts, and explained its relationship to other aspects of mathematics. Very critically, you presented the equations, you explained the intuitive portions to non-mathematicians, and you did it with the enthusiasm that is difficult to glean from dry textbooks. Love your UA-cam posts and your appearances on Brady's videos. Keep up the great work.

    James, sincere thanks for following through on this request by interested viewers like me, I am familiar with the content but the nuances continue to grow over time. The internet access to information sources like these youtube channels is a stunning contrast to when I was first introduced to it reading a paper back copy of "Stalking the Riemann Hypothesis by Dan Rockmore" around 2005 "by candlelight". Watching this now three or four times over two days was again similarly juxtaposed personally.." very exciting" and a thoroughly helpful addition to the initial "incredible read" experience. The interval between then and now is remarkably influenced and is clearly given me access to real structure by better understanding the mathematics, especially in the margins of addition and multiplication. The theorem's wide appeal to many pursuits is in itself remarkable. In all the video here is "Exquisitely arranged material and lucidly presented with admirable understanding and enthusiasm in a skilled detailed explanation". So much of what excites me about mathematics is how much there is to learn and the many open questions still abound in this wild field... exploring the unknown... and its good to leave a trail!

      There's a Japanese club for families to learn a bunch of languages, and the funny thing is that the guy who started the club requires people who join, as their first assignment, read Heisenberg's book on quantum theory.
      He says that it won't make any sense to you, but that if you're going to learn new languages you're going to have to get used to reading things that don't make sense to you...
      Though, obviously, some of his members did come to understand Heisenberg's book because they published a book that goes through every single step of proving that Schrodinger's wave equations are equivalent to Heisenberg's version. It was written by students who had just learned it, on the theory that you're better at remembering all the details and explaining something that you've just learned. And it's very Japanese, full of cute little cartoons and asides like how to draw a cartoon the physicist De Broglie, who's face is shaped like a peanut.

    Remember nada de futbol
    Until you finish the work you have
    Y me daba una sonrisa
    Y yo me quedaba loquito
    Y despues en el examen
    Lo ponía todo al reves
    Carito se fue del valle Yo la recuerdo cantando Porque me dejo muy triste cuando Para su tierra se fue
    Carlito dime que si, me eneñaras todo
    Para no quierer morir per te…….

    Que me muero por tu amor
    Que importa la raza
    Tampoco el idioma
    Si al fin lo que cuenta
    Es lo buena persona
    Si es del altiplano
    O de tierra caliente
    Si al fin lo que vale

    The 5 travels down the grouping of 6 from the 5th position to the first position to the 25 and cancels out the right prime to 24.
    The 7 travels to the right through the first position back to the first position of 48 and cancels out 49.
    The squares of primes cancel out other primes. That is why the number of prime numbers less than a certain number follows the inverse of the log

    Are you aware that there is a direct correlation between your enthusiasm and emotions attending this explanation and the actual rigor used in the ramping up of your description? It's almost melodious.
    What if numbers and math have human emotive and fantastical elements to them? What if math is an endless song or a dance that we can't sing or sway to because we lack the dimensional articulation? Thus it behooves us to merely express things mathematically using one-dimensional verbal or written symbolic gesturing.
    This idea is only partially reflected in the quiet passion of too few mathematicians or scientists.
    John Nash understood it.

      +Peter McMillan Agreed. Especially where he spoke about proving that the zeta function has no zeros on the line of the real part of S = 1. Hurrah.
      Likewise from the WIKI, "In a lecture on prime numbers for a general audience, Fields medalist Terence Tao described one approach to proving the prime number theorem in poetic terms: listening to the "music" of the primes. We start with a "sound wave" that is "noisy" at the prime numbers and silent at other numbers; this is the von Mangoldt function. Then we analyze its notes or frequencies by subjecting it to a process akin to Fourier transform; this is the Mellin transform. The next and most difficult step is to prove that certain "notes" cannot occur in this music. This exclusion of certain notes leads to the statement of the prime number theorem. According to Tao, this proof yields much deeper insights into the distribution of the primes than the "elementary" proofs."
      Maths are the tools, but music is the spirt.

    • @lamudri

      @MultiplyByZ3r0 11 років тому +2

      It depends on whether you're an engineer or a mathematician, the former uses ln for natural log, the latter, log and they say log 10 when they mean log 10.

    • @deskgo
      @deskgo 11 років тому +5

      Because the natural log is more important in maths and log10 is better for applications. You are right that log should mean log 10 but log 10 is not very useful in math theory so log tends to mean natural log which is much more useful.

    • @singingbanana

    If someone still reads this: it is often said, if we could prove the Rieman Hypothesis, it would give great insight into the nature of primes. Is that the case though? We already have that insight, we just can't prove it's the correct insight. Proving it just means: "yes, what you now only assume is true about the nature of primes, definitely is true". In a way that's how every other science than math operates all the time. Just assuming.

    @jorgerichards23 10 років тому +1

    Hello, I watched the whole thing and I think I fairly understood the behaviour or the function and the relationship to the primes and the prime number theorem, and the proof would be showing that all zeros have to lay in the +0.5 line and non can exist in any other place. I have heard (or maybe seen in a few TV shows and movies) that proving Riemann's Hypothesis could have security implications since internet security is heavily based on prime numbers operation. My question is, what result could that proof yield that would be more significant than the results Riemann did making the hypothesis? Maybe a specific formula for all the non trivial zeros? Didn't he did that already? Could someone just assume it is true, use the final results and work something out? Or was Hollywood messing with my head again? I mean Riemann already worked out the consequences of it being that way, are there more consequences for knowing for sure it IS that way?

    I really think it's pretty crappy that you don't get the prize for disproving it. Wouldn't it be funny if someone disproved it and kept it to themself since there wasn't an incentive to share? Of course, that's impossible because anyone that dedicated to mathematics wouldn't be able to keep it a secret.

It' makes sence that if you find the counter example of the one zero that doesn't lie on critical line means that all zeroes (except obvious ones) don't lie on the critical line, which is contrary to the RH. In that case RH could not be proven....:/
