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 RUclips posts and your appearances on Brady's videos. Keep up the great work.

I find it interesting that I watched this video about 2 years ago when I was 17, and I remember I didn't understand somethings. Now I'm on college, and I decided to watch this again, and surprisingly enough, I got a lot more of what he said. It's nice to see our own development in practice.
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.

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

When you say log(x) are you referring to log_e(x)? It seems no one wants to keep consistent notation with it. Also, I'm happy you finally did a more intense video, but I find it sort of funny how people are acting like it was a super difficult video when you glossed over all the actual difficult details. Even the residue calculations can get horrendous.
I cannot state having understood, but I'm greatly inspired to learn more to understand it finally. Thanks James and don't let the gap between consecutive videos be as big as those between big prime numbers! ;-)
I transferred from a community college and began my first quarter in an actual university in California (UC Davis). I transferred to study math but had no interest in it at all, it was just a way to move on. I wish I began watching your videos earlier, here and on numberphile. They've made some hard to grasp topics much more enjoyable and understandable, such as the video where you deal with the different types of infinity. I look forward to newer videos from you and everyone on numberphile.
I am currently doing a doctoral degree in Physics where I use the Riemann zeta function all the time. I had no idea of its origin or how interesting it really was, just kinda used it as a tool up until now. Great video, really enhanced my interest on the subject!
Sad thing is, I have the education necessary to watch this, but I don't have the patience to listen to him. I feel like I'm listening to a lecture from a professor asking myself the same question I did then "Why the hell do I even care about this?". No offense to the presenter, he is a great guy and math is his thing and I'm glad he can get excited about it. He's also made some other cool videos that have kept me entertained, but this one is for the egghead nerds for sure.
GameRage Dad I'm the opposite. I have no idea what he's talking about but I love listening to it nonetheless. Most of the reason may be his adorable, awesome accent.
Even though I didn't understand this enough to understand the Riemann Hypothesis, I still learned a lot from it. More of this so-called 'maths' stuff, please! :)
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.
the fact that i dont understand what you are saying makes my depression come back. I genuinely just want to know what mathematicians are talking about but i think as soon as i graduated high school i lost that skill
the number (0) is on the same line because it is a number guard it grows to forget and to the right and the center is still, just observe in the sieve of eratosthenes
It is not enough at 15:10 to point to the function Li defined at 3:45 for real numbers, because now you need a function that is defined also for complex number x^ρ, where ρ is a nontrivial zero. I realize this video is old. But is there a follow-up video which explains more in detail how to handle the function Li defined on a domain that includes non-real numbers?
Wow, this was very easy to follow. Granted, I just got my maths degree and I'm running through a book on the Prime Number Theorem now, but still I think you did a great job. You also gave me more motivation to keep ploughing through all these proofs lol. Thanks!
19:17 That's... Lame, I mean I get why, you want to pay the guy for showing up, shake some hands and say some words and being a symbol for the problem. But still that's not how math works, solving the problem means either proving it, disproving it or proving it's "improvability".
This is certainly the most insightful video I've found on the properties of the Riemann Zeta function. I'd just wished you could go more slowly over some of the steps, but they can be filled in with some effort. Great job!
Probably, but you should rephrase that to prime properties of fractals. Primes show up in almost every aspect of math; at this point it would be more impressive to prove something is not related to the primes.
A Solution for the RIEMANN ZETA FUNCTION is extremely valuable because It also point to Solutions for enhancing the HAMILTON GEOMETRZATION Poincare conjecture, Hodge Invariance conjecture as it relates to PRIME NUMBERS, TAYLOR INFINITE SERIES ,MACULIN SERIES and Doing Arithmetic past ZERO or Singularity as it is called in Analytic Geometry , and Algebraic Geometry, and it Directly points to the Prime factorization Algorithm , the Division algorithm, and the QUADRIATIC FORMULA This Solves many DIMENSIONS and RANK IN THE COMPLEX FUNCTION PLANE for MANIFOLD like The Kahler MANIFOLD ,CALIBU YAU MANIFOLD simeoustanesly and Points to Soulutions to the entire Millennium Prize Problems proposed by The Early 20th Century Philospher and Mathematician David HILBERT , Including the YANG-MILL Mass GAP , and the NP COMPUTATION time space COMPLEXITY problem also know as the Traveling Salesman problem
Dr James, I think I got a better chance winning the lotto than to win the mathematics millennium prize. I thought I had a shot in solving this hypothesis.
there's a very interesting book "Prime Obsession" by John Derbyshire, it is all about primes, zeta function, the riemann hypothesis, and Riemann himself :D
This is really an excellent video. Many RUclipsrs try to sacrifice facts and reality to make content more presentable/watchable. You didn't and that's why this video is a fest for me😂. Please make more videos like this!! Live long and prosper 🖖
Thank you James. This was a wonderful talk. It got me starting and stopping the tape excitedly and along the way you succeeded in filling some gaps in my understanding of this all-important problem. (Priceless!) Riemann was a part-time number theorist you say? But then he only stated the problem and couldn't hang around long (poor chap.)
I'm a physics student, I have a lot of math as well and I really like math, but I didn't get any of this :P I still really liked the video. James can really make such a thing really enjoyable!
Goldbach's conjecture works because all odds are even with (1) more and the primes are odd only divided by (1) summed the primes sum (1)(1) which is even
..I'm a bit confused. In Numberfile video on this subject ( Million Dollar Math Problem - Numberphile ) at 14:18 prof Ed Frenkel says that disproffing the RH will winn you prize. 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....:/
Is it a british-ism that you call 1/3 "a cubed" instead of a "a third"? The other ones seem the same as North American usage. He does this twice around 5.40.
Am I correct to assume that those symmetrical non-trivial zeros that you plotted do not in fact correspond to any actually known zeros because otherwise the whole Riemann hypothesis would have been disproven already? Isn't it a bit confusing then to just put them there?
Yes, you are correct. I guess he was just illustrating the fact that IF they were to exist as shown, they would have to be symmetrical about the ½ line. I agree that it may have been a little confusing to some people and he could have made it clear that he was showing hypothetical zeros. But a good video generally.
At that point in the story, we had only achieved that information. It was only later with the Zeta function that we got the idea of them beeing on a single line. Furthermore, that proves a point. Never trust a mathematician, and never ever trust a picture! :)
When I saw this was about the Riemann Hypothesis, I wondered if the 1+2+3+4+5+6+... = -1/12 thing would find its way in here as well, and was not disappointed.
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.
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 Jeroen J Exactly. And Jeroen, presuming you're from the Netherlands as well; I study mathematics at the Utrecht University and we use log as in base e, but in high school I was taught log was base 10 and ln was base e.
So can someone confirm that I've understood this correctly, the riemann hypothesis is equivalent to the conjecture that if the blue equation (at 11:54) is equal to zero it implies that the real part of the input is equal to 1/2?
i thought not the non trivial zeros when real 1/2 + it .we get than s= z complex number ,but the non trivial zeros from a Riemann siegel formula and not the blue equation at 11:54 i wait for others to confirm this answer ?
I think more plots of the various functions would have helped this video to be even more approachable. Also, more repetitions, relating where we are at a given moment to where we started out and where we're going.
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.
Thank you! I spend a lot of time speaking with my classmates (we are studing maths) about the series 1+2+3+... after the numberphile's video. I refuse their 2 "proof" (because I lerned in analysis 1 that 1-1+1-1+... doesn't converge, so it isn't equals to 1/2 and in the second video they set -1 in a formula (coming from a geometric series) where |x|

I think the best part of this video is he explicitly defined the Riemann zeta function across the entire domain. Most authors just give the infinite series definition and say “by analytic continuation” everywhere else. Which is totally useless
I had that idea for a while, but it seems that mathematicians proved a Riemann hypothesis for other number systems rather than the quaternions. They had more than a century to think about the idea of extension to quaternions had it been that fruitful. You should know, however, that even the very concept of an analytic function will not emerge unscathed when you extend your definitions to quaternions.
Thank you for putting so much effort and enthusiasme into your videos!!! It's because of you and numberfile that I love math's!! (Sorry for my bad English)

P vs NP is by far the easiest to explain. You can even explain it to a child. Now try that with the RH.
It gets abstract and complicated when you start working on it, basically like all the other Millennium Problems.
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
9:20 - This isn't strictly true, since he didn't explain the restriction that the function must be analytic.
Oh, sorry:( I hastily hit a thumbs down on you're comment w/o thinking. You are of course completely right.
CARITO BENAVIDES MONTILLA
MiUltimaHistoria
Pensaba yo en estos tiempos difíciles
Llenos de incompresiones y desencantos
en tantas buenas razones Para soñar
Y sin quejas, sin desfallecer, si… con todo
El agrado y los buenos sentimientos…
pensaba con nostalgia
De la inocencia de aquellos años
De esos primeros amores
Con yannette, teressitta, floralba…
Si… florssitta amore mio,
Que al recordarlas, vuelven a nacer
Y recuerdo en mi memoria
Aquellos tiempos de … de Carito
CaritoBenavidesMontilla diMugnoz
Mi bello, nuevo y gran amor….
Ella era una miss de Boston
Ocasellb: OcassoDiBellSetBuck
Que daba clase en la escuela di
Cullinnarii et pannes también…
Le gustaba el español
Y aunque lo hablaba poquito
Tenía esos ojos bonitos
Que hablaban muy bien por ella
Carito me habla en inglés. Aveces…
Que bonito se veía sola o en compañía
De unos que admiraban como io
Lo que jamas seria per me, perque
Io ya era cassado: con Florsitta, Con DianaCarolinna, y por supuesto, conLaFuncion Zetta di Riemann
Carito me habla en inglés et también en Italiano, germanny, francais, portuggisse,
Mandarin pictórico y por su puesto, En un quichua, básico para viajar por ecuador, peru, Bolivia, chile, y volver al final de tanto andar, de tanto amar,
de tanto padecer su belleza,
Que me dice: yo no se
Carlitos don´t be like that
Now listen to me
You will pay attention
I need you to write in english
Muy perfecto parragraph
And tell me where did you learn
Donde tu aprender to be tan coqueto
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…….
Carito don´t tell me no
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
Es que sea buena gente
Que importa su credo
Si es hombre de influyente
Si al fin lo que cuenta
Es la gente decente
No importa si es blanco
Si es pobre o famoso
Si al fin lo que vale
Es que cante sabroso
Pudiera escribir un millón de tequieros
Y algunos teamosrepletos de sinceridad…
Pero esta vez, ire lo mas lento posible…
Paso a paso, dia a dia, verso a verso,
Para que ni tu ni yo se pierdan
En tanta vanalidad en que habre envuelto
Mi extensa vida que alguien resumirá:
When you say log(x) are you referring to log_e(x)? It seems no one wants to keep consistent notation with it.
Also, I'm happy you finally did a more intense video, but I find it sort of funny how people are acting like it was a super difficult video when you glossed over all the actual difficult details.
Even the residue calculations can get horrendous.
I sympathise, even the statement is more advance than most people are familiar with. It is the natural log.
This video summarizes in 20 minutes all odd-numbered chapters of "Prime Obsession". I liked!
I cannot state having understood, but I'm greatly inspired to learn more to understand it finally. Thanks James and don't let the gap between consecutive videos be as big as those between big prime numbers! ;-)
14:10 Does anyone know a reference for the equation ζ(s) = π^(s/2) /(2 (s-1) Γ(s/2-1) )∏ρ (1 - s/ρ)?
Picturing Riemann doing a mic drop and saying "Peace out, y'all" had me dying.
I transferred from a community college and began my first quarter in an actual university in California (UC Davis). I transferred to study math but had no interest in it at all, it was just a way to move on. I wish I began watching your videos earlier, here and on numberphile. They've made some hard to grasp topics much more enjoyable and understandable, such as the video where you deal with the different types of infinity. I look forward to newer videos from you and everyone on numberphile.
I am currently doing a doctoral degree in Physics where I use the Riemann zeta function all the time. I had no idea of its origin or how interesting it really was, just kinda used it as a tool up until now. Great video, really enhanced my interest on the subject!
That's awesome - thanks!
I do not have the education necessary to watch this.
Sad thing is, I have the education necessary to watch this, but I don't have the patience to listen to him. I feel like I'm listening to a lecture from a professor asking myself the same question I did then "Why the hell do I even care about this?". No offense to the presenter, he is a great guy and math is his thing and I'm glad he can get excited about it. He's also made some other cool videos that have kept me entertained, but this one is for the egghead nerds for sure.
GameRage Dad I'm the opposite. I have no idea what he's talking about but I love listening to it nonetheless. Most of the reason may be his adorable, awesome accent.
khaled khunaifer You're hurting my brain.
khaled khunaifer yeah... you missed the complex analysis part, we all wish we can LOL
***** Seventeen with the math ability of an eight-year-old.
Even though I didn't understand this enough to understand the Riemann Hypothesis, I still learned a lot from it. More of this so-called 'maths' stuff, please! :)
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.
***** Sounds good to me.
+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.
+doceigen chaos theory proves the relation between you and me, music and me, mathematics and me, using mathematics.
the fact that i dont understand what you are saying makes my depression come back. I genuinely just want to know what mathematicians are talking about but i think as soon as i graduated high school i lost that skill
great to see you back with a video :D
Thank you, been wondering how complex numbers were needed to do PNT proof, am hoping to learn more about this material
I love this guy. Always very clear. Great video.
Is a great explanation of a non trivial topic, a wide background is needed but is understood with your guide! Great work! Thank you
Is it possible that it is true but there is no way of proving it? Or if it is true can we the be sure that it is also possible to prove it?
Good job my brother. If you are still there,thank you. I never understood riemann until today. You made it simple
Even though I have almost no idea what he was talking about, I still feel a little bit smarter just watching it xD
the number (0) is on the same line because it is a number guard it grows to forget and to the right and the center is still, just observe in the sieve of eratosthenes
Why am I even watching this? I understand about as much about math as a banana! ... *continues watching* ....
It is not enough at 15:10 to point to the function Li defined at 3:45 for real numbers, because now you need a function that is defined also for complex number x^ρ, where ρ is a nontrivial zero.
I realize this video is old. But is there a follow-up video which explains more in detail how to handle the function Li defined on a domain that includes non-real numbers?
Don't tempt me to switch my major to mathematics.
***** Perfect reply :)
I Wish I had the opportunity to do so when it was my time!
Wow, this was very easy to follow. Granted, I just got my maths degree and I'm running through a book on the Prime Number Theorem now, but still I think you did a great job. You also gave me more motivation to keep ploughing through all these proofs lol. Thanks!
Thanks. This one does have a higher threshold, but you were the ideal viewer!
19:17 That's... Lame, I mean I get why, you want to pay the guy for showing up, shake some hands and say some words and being a symbol for the problem. But still that's not how math works, solving the problem means either proving it, disproving it or proving it's "improvability".
If you disprove it they'll be bummed out
This is certainly the most insightful video I've found on the properties of the Riemann Zeta function. I'd just wished you could go more slowly over some of the steps, but they can be filled in with some effort. Great job!
Looking at graphs of Riemann Zeta, would it be wrong to infer there are some fractal properties of primes?
Probably, but you should rephrase that to prime properties of fractals. Primes show up in almost every aspect of math; at this point it would be more impressive to prove something is not related to the primes.
This is the first of your vids I have seen. I'm a new subscriber; you're obviously barking mad; I don't understand a word.
I LOVE it!
They're really not all like this. There was that one where I made a straw kazoo.
Every time I watch this, I understand it a little bit more.

10 years later, I'm still waiting for the proof that cat equals dog and dog equals cat
Dr James, I think I got a better chance winning the lotto than to win the mathematics millennium prize. I thought I had a shot in solving this hypothesis.
in tenth grade atm, almost got the jist of it, hoping I'll be able to understand better as I learn.
I've always wanted to know what the Riemann Hypothesis was about.
Thanks for making it a bit more accessible because wikipedia sure isn't helpful!
Thanks. I think the choice is a hand-waving explanation or a difficult explanation.
there's a very interesting book "Prime Obsession" by John Derbyshire, it is all about primes, zeta function, the riemann hypothesis, and Riemann himself :D
yeah very interesting book, it also talks about the connection between HR and physics
This is really an excellent video. Many RUclipsrs try to sacrifice facts and reality to make content more presentable/watchable. You didn't and that's why this video is a fest for me😂. Please make more videos like this!!
Live long and prosper 🖖
They paying one million dollar for this proof is like me paying 0,15$ for Lobster/Champagne dinner.
Thank you James. This was a wonderful talk. It got me starting and stopping the tape excitedly and along the way you succeeded in filling some gaps in my understanding of this all-important problem. (Priceless!) Riemann was a part-time number theorist you say? But then he only stated the problem and couldn't hang around long (poor chap.)
I'm a physics student, I have a lot of math as well and I really like math, but I didn't get any of this :P I still really liked the video. James can really make such a thing really enjoyable!
Goldbach's conjecture works because all odds are even with (1) more and the primes are odd only divided by (1) summed the primes sum (1)(1) which is even
What if...the answer to Riemann Hypothesis is the friendship we found along the way?
He's BACK!!!!! We missed you James :)
11:23 -1/12?!
NOT AGAIN!!!!!
lolzomgz1337 the curse of numberphile
..I'm a bit confused. In Numberfile video on this subject ( Million Dollar Math Problem - Numberphile ) at 14:18 prof Ed Frenkel says that disproffing the RH will winn you prize. 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....:/
Is it a british-ism that you call 1/3 "a cubed" instead of a "a third"? The other ones seem the same as North American usage. He does this twice around 5.40.
I'm British and it's not something I recognise. I'd even say he misspoke, but it could be a regional thing.
Excellent lecture - it brings light into a dark place. Quite enjoyable!
The harmonic series sounds nice, at least the first few terms. The seventh is a bit flat, though.
"What world would be there if you have no idea how to prove or disprove the Riemann Hypothesis?!?!"
-A concerned mother
Am I correct to assume that those symmetrical non-trivial zeros that you plotted do not in fact correspond to any actually known zeros because otherwise the whole Riemann hypothesis would have been disproven already? Isn't it a bit confusing then to just put them there?
Yes, you are correct. I guess he was just illustrating the fact that IF they were to exist as shown, they would have to be symmetrical about the ½ line. I agree that it may have been a little confusing to some people and he could have made it clear that he was showing hypothetical zeros. But a good video generally.
At that point in the story, we had only achieved that information. It was only later with the Zeta function that we got the idea of them beeing on a single line. Furthermore, that proves a point. Never trust a mathematician, and never ever trust a picture! :)
When I saw this was about the Riemann Hypothesis, I wondered if the 1+2+3+4+5+6+... = -1/12 thing would find its way in here as well, and was not disappointed.
Sadly been too long since I did maths like this. I'll leave the proof to you :)
strikingly beautiful, amazing clarity, please do more
Why is the English notation off the natural log just 'log'? Where I live, 'log' means log base 10 while 'ln' is used for the natural log.
I usually see “ln” in English, but I guess “log” just looks nicer and it's fairly obvious that we're not dealing with base ten logs.
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.
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.
Exactly what Ryan said. Mathematicians always mean the natural log.
singingbanana Jeroen J Exactly. And Jeroen, presuming you're from the Netherlands as well; I study mathematics at the Utrecht University and we use log as in base e, but in high school I was taught log was base 10 and ln was base e.
So can someone confirm that I've understood this correctly, the riemann hypothesis is equivalent to the conjecture that if the blue equation (at 11:54) is equal to zero it implies that the real part of the input is equal to 1/2?
i thought not the non trivial zeros when real 1/2 + it .we get than s= z complex number ,but the non trivial zeros from a Riemann siegel formula and not the blue equation at 11:54 i wait for others to confirm this answer ?
Yay youre making videos again.
I think more plots of the various functions would have helped this video to be even more approachable. Also, more repetitions, relating where we are at a given moment to where we started out and where we're going.
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.
You'd still be famous.
Oh yeah, I forgot to tell everyone, I disproved this years ago. It was so disappointing that I burned down my office with all my research.
I'm not 100% sure if he just made this part up or not, or where I could search to get a reference to that fact.
I think you would become the most loved and at the same time most hated person in maths.
I guess he meant disapproving with a rigorous proof will get you price. Disputing with a counter example won't.
Thank you! I spend a lot of time speaking with my classmates (we are studing maths) about the series 1+2+3+... after the numberphile's video. I refuse their 2 "proof" (because I lerned in analysis 1 that 1-1+1-1+... doesn't converge, so it isn't equals to 1/2 and in the second video they set -1 in a formula (coming from a geometric series) where |x|
Fermat be like: i know the proof. But this margin is too small to write it down

I think the best part of this video is he explicitly defined the Riemann zeta function across the entire domain. Most authors just give the infinite series definition and say “by analytic continuation” everywhere else. Which is totally useless
Define it for quarternions
I had that idea for a while, but it seems that mathematicians proved a Riemann hypothesis for other number systems rather than the quaternions. They had more than a century to think about the idea of extension to quaternions had it been that fruitful. You should know, however, that even the very concept of an analytic function will not emerge unscathed when you extend your definitions to quaternions.
Thank you for putting so much effort and enthusiasme into your videos!!! It's because of you and numberfile that I love math's!! (Sorry for my bad English)
Thank you!
That x = 0.5 line is called in some circles 'the dirty crease.' Modern maths seeks to know how dirty the crease really is. Get at it.
