    For those who want to learn more about the relationship between 1+2+3+4+... and -1/12, I'm quite fond of this blog post by Terry Tao: goo.gl/XRzyTJ
    Also, in a different video "What does it feel like to invent math", I give a completely different example of how adding up growing positive numbers can meaningfully give a negative number, so long as you loosen your understanding of what distance should mean for numbers: • What does it feel like...
    Interestingly, that vertical line where the convergent portion of the function appears to abruptly stop corresponds to numbers whose real part is Euler's constant, ~0.577. For those who know what this is, it's kind of fun to puzzle about why this is the case.

    As a mathematician, I was always deeply aggravated when other mathematicians on UA-cam or elsewhere said thing such as, "the sum of all the integers converging to negative one over twelve" or "an infinite sum of ones is negative one-half" and these are just true things they found out, and are simply mind-blowing and counterintuitive. Yet their methods of telling it to the audience were clearly way out of context. Mathematics should not be mystical, such that it becomes ungraspable; it should be explained and appreciated for its rigor and intuitive creativity combined. Thank you for this content, I appreciate it because it is detailed, but not overly rigorous for the sake of rigor alone, so that it becomes inspirational. That is what education in science and math should be: inspiring others to want to learn, rather than shoving the information in their skulls. Education in science and mathematics is something this country lacks in, and content creators like you can help change that.

    • @3blue1brown

      Wow, thanks so much. I definitely agree with the statement "Mathematics should not be mystical". It seems commonplace in outreach to use surprising facts to capture an audience that might not usually care about math, and insofar as this bring in more people who wouldn't otherwise be looking, that might be a net positive. But I do worry that tossing out only mysteries without arguments might have an overall negative effect on the public perception of mathematics.

      +3Blue1Brown Idk, whenever I finish one of your videos (or learning any super interesting new math topic) It feels totally mystical and unreal, even though I just saw or worked out the specific details on how and why whatever is happening is happening. It's kind of a "holy shit, this makes so much sense it can't be real".

    • @jmcsquared18
      @jmcsquared18 7 років тому +150

      Jacob Kantor I will admit something: mathematics, indeed all of the good sciences, have a lesson in humility at every stop. Sometimes, when I learn of some crazy fact, like that there are as many rational numbers as there are integers, which on the surface can't be true, but is proven without a doubt mathematically, I have to understand the context in which the statements are said. It is oftentimes impossible to understand mathematics or physics out of context, and trying to might make it appear nonsensical.
      For instance, in the context of set theory, we say two sets have the same size if and only if you can find a way to pair each element of one set with exactly one of another. It isn't the same strictly as counting the elements, but it's the more general definition that we need because we deal with infinite sets; you can't even properly say that two infinite sets have the same "number" of elements because the number of elements each one has isn't even a finite number!
      You then you realize that, with infinities, weird stuff can happen like one set having the same number of elements as another one that it is properly contained in. So context is everything in mathematics, because we often deal with abstractions that we intuitively attempt to relate to, but oftentimes are nothing like what we are used to.

    • @MasterHigure
      @MasterHigure 7 років тому +110

      I think he said it quite well in the "Who cares about topology" video, that children and laypeople might be told how to make a Möbius strip, and perhaps to cut it down the middle, but then they stop there without giving it any context. Why the Möbius strip is relevant to anyone, apart from its slightly funny one-sidedness is not usually discussed in these settings.
      Also, I'm very happy that this video is a bit critical towards the 1+2+3+4+... = -1/12 thing. I mean, the evidence as shown in this video clearly point towards a connection, but many other sources claim it's a direct equality. It is, in my opinion, the single bad thing Numberphile have ever done, for instance. As a person frequenting the math stackexchange, we regularly have people who come in there after stumbling across that one video and wonder what is going on, and whether they have misunderstood convergence completely.

      @RoboBoddicker 7 років тому +48

      Speaking as a non-math person, 3Blue1Brown's description here was beautiful and elegant and made sense. But it's also 20 minutes long, and that doesn't even include an explanation of complex numbers or the complex plane. Plus, just creating the visualizations he uses requires a complete understanding of the material. So I think it's a bit unfair to call out Numberphile for being superficial - it's just a different format. Hell, I probably never would have even considered watching this video had I not learned the basic ideas from Numberphile.

      The limit of a complex-valued function is defined in the same way as the limit of a real-valued function except that the real absolute values are replaced by complex absolute values (complex modulus). If you are familiar with the ε,δ-definition of a limit, then basically we are replacing the intervals on the line with disks on the complex plane. And if you can take the limit of a function, you can apply the exact same definition of a derivative for functions on the complex numbers that you can for functions of the real numbers. However, it turns out this limit only exists, and thus the complex derivative only exists, if the function satisfies a particular pair of conditions called the Cauchy-Riemann equations. A geometric interpretation of these equations is that the angle of lines intersecting anywhere but the origin is preserved under the transformation defined by the function.
      So it is not so straightforward. The upshot is that if the complex derivative exists, then it's continuous, and in fact derivatives of all orders exist. More than that, the function is analytic (at every point, there is a Taylor series that converges on some neighborhood of the point and is equal to the value of the function there), which is the relevant property in this video. These facts are not trivial at all, and they are central theorems in complex analysis, along with the identity theorem mentioned in the video (that analytic continuations are unique).

    This is the most easily understandable explanation of numerous things, including analytic continuation, complex analysis, and the continued zeta function that I’ve ever seen. And I say that as someone 50+ yrs old who has had a tremendous facility with math since I was at least 4 and generally taught myself most mathematics before I learned it in school, including many aspects of trig and calculus. And by “taught myself”, I actually mean figured it out on my own, not that I picked it up by studying a book. Books largely just connected my self-learning with accepted terminology, but did offer expanded views and results of what I figured out on my own. It wasn’t until calculus that I started encountering a significant amount about math that I hadn’t figured out on my own.

I look forward to more videos, cheers :)

    Very nice talk, your presentation is almost accessible to the general public. You explain very well that the sum of Ramanujan series is not strictly speaking equal to -1/12 but it takes its sens as an analytic continuation of an holomorphic function beyond its convergence domain on the complex plane. Excellent video. Many thanks.

      Well, except if you can prove it then you can really prove hundreds of theorems. If you disprove it, then not only many theorems are disprove but also many important ones remain unproved. So both are ground breaking but the latter is kind of ugly.

    • @BiophysicalChemist
      @BiophysicalChemist 7 років тому +3

      John Skeff Nope, you only get the money if you prove it. A disprove would be finding a counter example, but anyone who has intuition for complex analysis would tell you they have no doubt that it is true. The solution is most likely pretty simple too, it's just that no one has found the right way of thinking about the problem that makes that solution clear.
