The Riemann Hypothesis, Explained
HTML-код
- Опубликовано: 17 май 2024
- The Riemann Hypothesis is the most notorious unsolved problem in all of mathematics. Ever since it was first proposed by Bernhard Riemann in 1859, the conjecture has maintained the status of the "Holy Grail" of mathematics. In fact, the person who solves it will win a $1 million prize from the Clay Institute of Mathematics. So, what is the Riemann hypothesis? Why is it so important? What can it tell us about the chaotic universe of prime numbers? And why is its proof so elusive? Alex Kontorovich, professor of mathematics at Rutgers University, breaks it all down in this comprehensive explainer.

My math professor once said, “I’ve know the existence of these math problems for many years. And I assure you, there are a lot easier ways to make a million dollars”
lmaoo
One has already been done - and the prize turned down. Fermat's last theorem would have been a Clay Institute award but was solved before the prizes were offered, but Andrew Wiles has received prizes approaching £3 million and a knighthood which isn't so bad really.
did you asked how to the professor?
I like your teacher
Compared to such an achievement, a million dollars feels so trivial it's almost humiliating.
I have discovered a truly marvellous proof of this, but it's much too large for this youtube comment to contain. Therefore it is left as an exercise to the reader.
Omg Fermat no! You can’t do that!!
this is the way.
me too
Rh is true because I/2
Pft. Whatever, Fermat.
This is like becoming an astronaut, discovering a previously unknown planet, finding a river on that planet, and at the bottom of the river is the perfectly fitting other half to a broken rock you found in a river on Earth as a kid. The Universe sees the look on your face and laughs silently.
That's what I call a good trip.
This is stupid - there is no magic man laughing at us - stop with these childish ideas
It' has always been plain that we're dealing with a partialy identified/defined state of existence.
Everything we see are aspects of a whole that we have not yet put together. We know this because reality is currently completely unclear and objectively (essentially) meaningless to us. The fractal isn't yet plotted (It may never be).
When we see the truth of material existence, all answers will suddenly fit together and fill out the description of the whole, seamlessly.

nice pun

True, Evelyn. That can be a challenge for truly gifted matematicians- to level down and communicate on ‘lower’ levels. The author shows some pedagogical talent here

@@k-force8325 yes, they had what is called "mechanical calculators", which is something like an automated abacus via gears. And they were HUGE (in modern standards) and WEIGHTED a ton... For example, you have the "Pascaline" built by Blaise Pascal, and it was an "Arithmetic Machine" in 1642.

I agree, Riemann, Euler, Gauss, and other mathematicians and physicists are truly amazing. Their work has had a profound impact on our understanding of the world, and their discoveries are still being used today.
I'm glad you enjoyed the video! I put a lot of work into the animations, and I'm always happy to hear that people enjoy them.
I think one of the things that makes these mathematicians so special is their curiosity. They were always asking questions and trying to understand the world around them. They were also very creative, and they were able to come up with new and innovative ways to solve problems.
Whoever does these animations, massive props to you. These are literally the best math illustrations I've ever seen.

Literally if my math teacher had just said “logarithms are to exponents what division is to multiplication,” I would have had much less trouble with them. Thanks dude
It's a bit more complicated than that, though, because exponents have roots as well.
@@jdeep7 idk what that guy is talking about with roots but I guess the complex logarithm isn't a well defined function since there are infinitely many possible imaginary parts for a given input
@@jdeep7 Exponents and powers are often taught in school as the same thing, and the inverse of a power function is a root. Is the reverse of 2^3=8 cbrt(8)=2, or is it log2(8)=3?
right?!
Pretty sure teacher himself did not know that
When pure mathematics comes with lucid explanations, and the two are complemented by a perfect vanilla icing of aesthetic graphics. A million thanks for this amazing presentation.
This video goes so well with the 3blue1brown one. It explains the Riemann zeta function in more detail and helps you get an actual feel of the 0's, especially the trivial ones.
But like all other Riemann zeta function videos I've seen before, they say 'it's important for primes' and refuse to elaborate.
NOW I understand, thank you!
At least, I understand enough to appreciate it. I've wanted this for so long. Thanks, once again! Also I never appreciated how much of the Riemann hypothesis was actually done by Riemann himself. What a juggernaut! I thought he laid the foundation and it stopped with 'I think the zeroes are on 0.5' and that someone later realised the connection with primes.

I've watched many videos on the Riemann Zeta function, but this one is now my favorite. It connects to the primes beautifully. Alex, you've done the world a wonderful service. Thank you!
Just discovering the Quanta math videos. These are my new favorite math explainer videos because - they take on difficult mathematics that I actually want to know about, explain it thoroughly and artfully, with stunning animation that is both entertaining and very well thought out, and makes it all seem easy and inevitable. And having a narrator who has a great voice AND is a personable mathematician seals the deal.

RUclips: How bout Riemann Hypothesis?
Same here.
Same
🤣🤣🤣🤣🤣🤣🤣🤣
actualyl same
Oof, true, what am I doing at midnight here, RUclips?
I have watched countless videos about the Riemann Hypothesis, the Riemann's Zeta function, etc. And this is only one that actually explains the connecction between this function and the distribution of prime numbers. The harmonics part has never been explained to me before. Well done, now I can finally truly understand why this is such a big deal for mathematicians. Well done!
I was just thinking exactly the same about this video in particular, an and I've watched hundreds of vids and read dozens of books.
it has to do with fourier analysis. because the function with the log of the primes can be written in another way so that the part where you put in the zeta zeros has a cosine. that means that every zero is like a wave. and if you add all those waves together you get this function in 14:26
it is kinda ironic for a musician like me to watch a random math video and hear harmonics mentioned, like what if all the math mental gymnastics is reducible to waves and harmonics ?
Indeed.

This is literally the best video on RUclips explaining why the Rieman hypothesis is related to the prime numbers and why proving it is so important. Other videos only briefly mentions that it's important because the 'prime number distribution is encoded in the function', like bruh that doesnt explain it enough. This video also beautifully shows how anaylitcal continuation works.
Yeauh my mind was blown when they shouwed the harmonic sums converging
This video also has some beautiful animations and historical informations. I love to understand math with context and this video makes a great job!
Agree
Not really I felt like this didn't explain much for those with some background in Maths, and is prob still too difficult for those without a background to understand. But can't really blame the video since it's only 15 min long
I wonder what they do with the Riemann hypothesis in quantum physics research...
Being from an engineering background, even I understood the hypothesis. Your video was unbelievably awesome.
Ditto, though for some steps I would have loved rigorous definitions instead of pattern animations .
There should be a nobel prize for the efforts in teaching so complex subjects in an affordable way like this video does. Awesome job! Greetings from Brazil!

Thank you so much! If I had these videos during my mathematics studies it would really be more fun. And surely result in more passion.
If the math itself isn't enough to bring out your passion, what would attracting a bunch of lay people to the field accomplish? You'd get even more morons like Terry whatshisname who insists on Terryology, where 1*1 = 2, just because he couldn't understand basic grade 1 math.
The production quality of this content is insane.
For those who saw Beautiful Mind, this was the puzzle Nash was working on at the end of the movie. There is a Dover book from Edwards, "Reimann's Zeta Function". 305 pp. The first 25 pages explain Reimann's original 8 page paper. The rest of the book tackles developments since 1859 (up to 1974). Edward's book is presented as a guide to the primary sources. If you saw "The Man Who Knew Infinity", Hardy and Ramanujan also did work related to the conjecture. Turing also worked on the problem, taking a computational approach. Just so you know the competition and how it relates to nerd culture. I get stuck just trying to draw a Greek Zeta.
Edwards has written several great books, not only this one but also books like Galois Theory and Fermat's Last Theorem. They are not easy, but if you put in some work, you'll find the beauty of mathematics. Edwards died November 10, 2020, 84 years old.

Unfortunately, despite the rhetoric, most maths pros, like Riemann himself, really don't want know why R's zeta formula functions as it does, nor why RH remained unsolved for more than 157 years. Also, like Riemann, nor do they want to learn or do anything other than what they are doing inside The Box of the current paradigm of their fave maths niche. If that were untrue Riemann could have solved RH--IFF he could've gotten out of his tumnel-vision syndrome (& outa The Box). Also, if the culture of current maths was not allergic to superior theory & metatheory of maths & logic it would be easy to get my proofs reviewed, published & verified. As is, that's almost impossible. Sigh...seems a shame to let 21 years of good work and next-gen maths go to waste.

Unlike many tough math problems, the general consensus is that no one has a clue for how to solve this. Most of the progress that has been made has been to show that it is equivalent to other conjectures, but no one knows how to solve those either. The Wikipedia article has a decent list of some facts, which if proven, would imply the Riemann hypothesis.
It is complicated. There even is this de Branges thing (if somebody who is not a total nutcase writes down a proof attempt and nobody feels like checking it as that would be too much work)

@@y__h It can't be. Why? If you prove RH is undecidable, it follows that a counterexample cannot exist, which implies RH is true, which implies it cannot be undecidable.

This guy explaining imaginary numbers made more sense than when I learned about them last year in class
Complex numbers would make much more sense if you were shown it in its most useful applications, such as electric signals, or mechanical movement. In the Euler's formula, you can see as how a complex number can be understood as consisting of two components: one cosine function to depict the horizontal component, and a sine function to depict the vertical component. Imagine a circular movement of a point in that plane. For each point, there is a cosine component, giving you the projection onto the horizontal, and a sine component, giving you the projection onto the vertical.
It boils down to a simple triangular calculation. A point in a plane can be expressed by its Cartesian coordinates, or, by its Polar coordinates.
Consider the imaginary i to map a 90 degree angle on the complex plane. Each time you apply one times i, you move by 90 degrees counter-clockwise. Travel twice 90 degrees (twice i), and you have traveled 180 degrees: you have reached -1. Continue so, and each time you jump one time i, you jump 90 degrees counter-clockwise.
It's what we call "quadrature". It is applied in Fourier analysis and integration, and very practically in decoding movement and speed direction of electric motors. A motor-decoder detects the rotation of the motor's axis by using two detectors that are aligned in such as way as to register the axis movement with a 90 degree difference between both detectors. When the movement signal has stabilised the signal of one detector, the other detector is picking up the change of its signal and triggers the output to switch. The output is always well defined by this design, as both detectors never have an overlapping status of their signals. A quadrature design is very clever.
It is also very useful in the synthesis of complicated signals by mixing a sine and a cosine function, rendering any intended electric signal (as applied in medical ultrasound devices).
Fourier analysis, quadrature applications, they all revolve around that same concept of complex numbers. It's not just mathematical theory, it is very practical indeed.
That's because there are literally a gazilion bad math teachers. This figure was determined using "alkh3myst's conjecture".
@@Guido_XL they make more sense but are still a pain in the butt. It’s so easy to flip a sign.
To be fair, though, it's much easier to understand the general problem as presented in a 16-minute video, where the rigorous proofs are omitted and the details smoothed over, than to understand the technical details or to work with the precision required by a semester-long course.
I studied this hypothesis as a senior math seminar project in undergrad. Very tight and clean synopsis. Wish this video existed back then.

Of course there's a lot of content surrounding the Riemann hypothesis (and the zeta function more generally) that this video didn't cover, and much of that absolutely requires a post-doc level grasp of math to fully understand.. but the video only touched on the surface level stuff and that's not nearly as difficult to grasp.
forget about professorship, all you need is to tame the zeta function and play with it, interrogate it or even torture it sometimes, it will spit facts
This seems pretty easy to solve though, I'll give it a try tomorrow.
You're joking right
@@dtp0119 Obviously not.
Let me know how it goes
@@TheodoreServin As I expected it was pretty easy to solve. I won't release the answer though because that would take the fun away from the people still trying to figure this (rather easy) equation out.
Right between breakfast and cold fusion.
Hi Quanta Magazine
Thank you for the wondeful topics you teach us. 🌻
I only understand half of the video could you please explain more about the second half .
At some point I didn't understand anything but I kept watching cause the animations are just so crisp
the production quality on this is way too high for it to only have a million views. it explains the subject so well with such a unique art style in such a short amount of time. keep up the good work
Incredible. The reveal when all the harmonics are added in and its the primes is fantastic.
Yes, that amazed me. Like Fourier synthesis, but for prime numbers. Wow.
This is the best video I've watched in a long time. I made my way here from a video about Mertens Conjecture.
I thought you said I DIDNT need a degree in mathematics to follow you through this journey.
If you have taken up through calculus 2, you should be able to understand at least the basic idea of the video. Even still don't feel bad. Rewatch the video, take good notes, and you will understand it better.
As a physicist, this told me I'm an idiot.
There are strong links between the Riemann hypothesis and quantum physics. Many believe that the hypothesis will eventually be proved by a physicist.
@@peterboneg well I'm aerospace engineering and I focus more on classical rather than quantum.
I have an IQ of approximately 149.
This stuff still makes my head hurt
@@AmikaofMan You remember the Stephen Hawking quote?
@@maxwellsequation4887 Yes I've hard that one also my friend but stating my IQ was not in boast, sorry to break your heart. It was fact but also STATING that I DON'T KNOW EVERYTHING
Great respect to animation as well as speaker..so easily clear the most hardest concept ever..
Excellent, informative video with truly knockout graphics.
Massive props to you for this video. Excellent voice work, animation and music. Re. the content - I learned enough to know that I'd never cut it as a mathematician. But this is about as approachable an explanation as I think anyone could ask for. Thanks for producing this.
Love the way you illustrate your vids!
Great video and explanation, it really cleared out why its so sought after.
Very nice video. Despite being fairly mathematical, I happened to never technically encounter the Reimann hypothesis or taken the time to really understand it until I watched this video.
If you want to get familiar with the Riemann zeta function, try to proove the following:
If you only take every second summand of the zeta function (see 9:42) for a given value of s and draw the intermediate results for the first summands one at a time (similar to 10:03), you get a graph that converges to an outgoing 'spiral' that gets slower and slower, i.e. needs more steps to complete the next rotation than the previous one. You can draw one spiral for the summands with odd 'index' and one for those with even 'index'.
Try to proof:
1. The centers of the two spirals will be at different points unless the input (s) is one of the zeros of the original function.
2. The centers never exactly meet for any other input.
3. The centers only meet at the origin (0, 0).
4. There is no input for which only one of the centers is the origin.
You might need to find a useful definition/formula for the center first.
You might need to exclude trivial cases for some of these.
Visualizing this first by plotting the graphs and playing around with the parameter s might be useful.
Try to plot both spirals in the same plot. Try flipping the signs to align them.
You can assume the Riemann hypothesis to be true if you need it for a proof.
Some easier tasks for warm up:
a) Which formula describes the length of the nth summand of the zeta function? In other words: What is the distance in the complex plane between two consecutive intermediate results, i.e. between the results for the first n-1 summands and the first n summands?
b) Which formula describes the angle of the line segment between those two points in the complex plane?
c) Can you use this to formulate the zeta function with two dimensional vectors and without complex numbers?
d) What if you only take the summands with odd/even index?
Someone reply to this comment later to remind me to learn all these terms. It would probably take me about 30 minutes to even comprehend your comment.
Learn all these terms
This is the best video explanation of the Riemann Hypothesis. Thank you for taking the time and effort to produce it.
Thank you for this excellent explanation of how much I don't understand the Riemann hypothesis!
This channel should reach 1 million.👍🏼
What a content,nicely explained.
"No you don't need an advanced degree in mathematics to go on this journey with me." I was lied to!!!
He never strayed beyond high school math. The problem in the US, is that most schools do not teach their students high school math. They are too busy prepping everyone for the exact questions on the standardized tests.
@@princeofcupspoc9073 Thank you for the passive aggressive insult, but I'm from Britain.
@@matbroomfield Probably holds true here as well, mate.
@@Upstreamprovider :-) thanks
@@princeofcupspoc9073 ...what high school did you go to, where they taught complex analysis or wave functions!?!? I'll admit, I'm from the USA, but we only went through infinite series in my high school
Fascinating and informative. If only we could pass the current state of knowledge back to the masters. What would they think or did they just know. 😮. Thank you
Interesting topic but the animation was the cherry on the cake. Simply beautiful!
I've known of the Riemann Hypothesis for a bit now, but never bothered to try and understand it because I thought it was beyond my comprehension. But wow this video did a great job at explaining what it says, what lead up to it, and what is significant about it. Thank you to all who made this for expanding my understanding!
Just read that an Indian mathematician solved this - His name Dr Kumar Eswaran.
same
Me too
There is no mention in any of the western media as per google search. One Indian newspaper said it was being reviewed since 2020 and over 1200 mathematicians were invited to review. In order to participate the mathematicians had openly declare their affiliation.
That is the first time I have come across some one who has explained the Rieman Hypothesis , as some resolution, that allows us plebs to understand it some level intuition. Thank you. Rather than state the name and leave it at that. Thank you.
👍
