not quite true - Grigori was willing to accept the 1,000,00.00$USD prize however on condition that the award was co-awarded to another mathematician Richard S Hamilton the pioneer of the Ricci Flow whom Perelman credited with providing the basis for his own work - the committee declined to do this and instead simply withdrew the prize money denying both Perelman and his fellow mathematician Hamilton - I quote "Perelman refused to accept the Millennium prize in July 2010. He considered the decision of the Clay Institute unfair for not sharing the prize with Richard S. Hamilton and stated that "the main reason is my disagreement with the organised mathematical community. I don't like their decisions, I consider them unjust."

[@TheVivi13]

Really? I've been introduced to complex numbers in probably like 10 different classes at this point and it's always in a similar fashion to this. Saying that we simply cannot say sqrt of -1 doesn't exist so we assign it an imaginary value which then creates a complex plane.

[@NateROCKS112]

@@TheVivi13 however, the main reason it's a cartesian plane (i.e., one with both basis "vectors" being orthogonal) is due to a slightly deeper property about i.

[@ypey1]

I have heard this explanation of complex numbers many times, but they often fail to explain the benefits of not discarding the i. That keeping the i in there opens up a whole new world of possible transformations and calculations. Continuing math beyond its borders. Like Rieman was extending the zeta function beyond its borders.

[@NateROCKS112]

@@ypey1 for most stuff, it's just a utility thing. You _could_ try to represent everything as a 2D vector, but complex numbers can be treated exactly like real numbers in most cases, so they're easier to work with, e.g., with exponentiation. For example, you could also represent negative numbers as a subtraction problem (and indeed there's a construction that does this), with a tuple of, e.g., (1, 3), but it's so much easier to just call -2 a number. Edit: The comparison isn't exactly the same, since vectors and complex numbers have different algebraic properties (whereas the tuple construction is a construction of the model of, say, integer arithmetic, so it has the same structure).

OK, Riemann hypothesized that on the vertical line through s=1/2, all the non-trivial zeros will be found there. If we cannot prove it to be correct, we have to assume it is correct because supercomputers have found billions of billions non trivial zeros on this line. Maybe it can never be proved correct or incorrect by mathematicians. How about we accept it like 1+1=2 although Bertrand Russel wrote a book to prove this, but who really cares 1+1 is not equal to 2?

Million Dollar Math Problem - Numberphile

[@sunkhirous]

Numberphile The roots are S=0+(pi +,-2pik)i/lnp^n , n=1,2,4,16,...

[@SicariusWolf]

Numberphile Well my brain hurts ill come back after college and try

[@herennow155]

Numberphile Did you not say that zeta function is valid for values more than 1, so why do you include negative integer line in your video?

[@randomensign2437]

Sid Sharma The series representation for the zeta function is indeed valid only for those values of s whose real part is greater than 1, but there is a fancy technique called analytic continuation that allows us to define the values at, say, negative integers. This analytic continuation is perfectly well defined at the negative integers, but more importantly is equal to the summation for values bigger than 1, so we sort of abuse the equals sign and just say that the zeta is in fact the series.

[@herennow155]

RandomEnsign but i only see that with negative zeta function, the series will be divergent. how can e.g - zeta(-4) which is equal to 1^4 +2^4 + 3^4 ........... be convergent?

[@cscooperau]

Could we possibly get a video explaining how the non-trivial zeros relate to prime number distribution?

[@crazedvidmaker]

Get a master's degree in number theory

[@cscooperau]

Andrew Christensen Too busy doing PhD in telecom

[@jeremyj.5687]

Yeah, this is kind of the elephant in the room after this video. I have no idea how the two are related and I´d really like to know. Maybe we´ll get an "Extra Stuff" of this video.

[@cscooperau]

Jeremy J. I am aware of how the behaviour of the Riemann Zeta Function relates to Prime Numbers, because it is equivalent to an infinite product function of all Prime Numbers. Also, the Riemann Hypothesis is equivalent to another conjecture that states the error of the Prime Counting Function has a definite limit. However, I'm not sure how the non-trivial zeros are related to it.

[@babelbabel2419]

His enthusiasm is contagious. A great teacher and a great video! As a side note, the -1/12 result for s=-1 (it's also one the Ramanujan equations) still baffles me although I've watched excellent videos about it. I get it that we should say it's a super-summation and not a regular sum (the series is still divergent with a regular summation). But the fact that that very result explains the Casimir effect in real world physics is akin to magic.

[@TheDiggster13]

I could spend an entire day listening to this guy talk! He's so entertaining to watch.

[@ayoubab2120]

the Riemann haircut looks like the integral symbol

[@lux27.42]

hahahahahahhahahahaha.....

[@benjiusofficial]

He walked the walk.

[@olivervalmes170]

😂😂😂😂😂

[@footie21]

Don't have the foggiest what is going on mathematically here but I love his accent so I'm still watching.

[@mjzudba5268]

I came from Veritasium's video about his deeper and richer love for turbulent flow and bias towards laminar flow. It was a nice video.

[@villanelo1987]

I love the random "keep watching!" message. Do they think we are going to say something like: "nope, this video is longer than 4 minutes... that is too much interesting information for me today!! I have to stop watching RIGHT NOW!!" xD

[@Rick_McDick]

I think it was to quell all of the youtube math experts starting a shitshow about how that particular sum is -1/12 because they watched Numberphiles other video

[@TheMrvidfreak]

Did you notice what was being discussed right when the annotation appeared?

[@Darwin226]

It's because he says 1+2+3+... doesn't equal any number and they have a video about it equaling -1/12.

[@kylobite]

I think it is more to prevent pointless questions/rants in the comments that could be avoided if they just watch the next few seconds.

[@lukasdon0007]

It's because otherwise people would all immediately pause the video in utter outrage because they KNOW 1+2+3+4... = -1/12

[@fireemblemaddict128]

When I saw 3:30 I started to scream. That -1/12 videos still haunts me.

[@rolandk2403]

I didn't know I was supposed to have a favorite fraction! :) (5:20)

[@AAAIJungwon]

Came here to see this great video after watching the recent podcast with Lex Fridman. So much passion in his eyes!

[@KabooM1067]

I freaking hate zeta. Everyone writes it differently, it drives me crazy. One of my professors writes it as 'ro' and the other writes it like small 'delta'. Aaaaah. I just write it like an S with a curve on top, just like I see it in print.

[@robertcromack5894]

+prepareuranus Yeah, it kinda helps to understand complex things when the symbols are instantly familiar.

[@duckhuntergaming4713]

It's the Greek letter for z, check it out to get a better sense of how it looks like. ζ

[@XenophonSoulis]

In Greece we write it ζ as in the KZbin script.

[@NomadUrpagi]

True. Mathematicians so often mess up with their greek letters that their deltas look like gammas and etc. Everyone writes greek letters as they can without properly learning to spell em like greeks

[@nixonkutz3018]

I like that he explains sqrt(-1) is called "i" because "we imagined it." There's still plenty of debate about whether "real" numbers are any less just a product of our imaginations!

[@blacktimhoward4322]

Not among smart people :)

[@gregorsamsa1364]

They are

[@SonnyBubba]

They’re real alright. Every electrical engineering student is well aware of their existence.

[@ethanlawrence2825]

I love how he writes his zetas. Great video. :)

[@nyamuda]

This is the best explanation of the Riemann Hypothesis I’ve come across. Thank you for breaking it down so clearly.

[@cicartaya]

I like the way this guy speaks.. sounds very knowledgeable

[@arimanno74]

A beautiful lesson. The better explanation of riemann zeta function that expose perfectly and clearly how simply and beautiful is to arrive on the wall of the 1 million dollar question. I am beginner in math, but this take me exactly at the base of the wall. Excellent.

[@r6854]

Wow, you can feel this guy's passion for math

[@rakeshmallick8040]

This is definitely the best Numberphile video. Mathematics is beautiful but the way in which maths is taught in classrooms around the world makes it boring and disinteresting. Thanks to videos like these , channels like Numberphile and applications like Mathematicia, Wolfram Alpha and Matlab, learning maths becomes exciting.

[@MaraK_dialmformara]

Please do a video on the Millennium Problem that's been solved?

[@oO_ox_O]

Yes, Brady should interview Perelman! ;) The first real interview ever since then.

[@AlltimeConspiracies]

Fantastic video! Thumbs up from ATC!

[@Sylocat]

I love the "keep watching" at 04:13, you know exactly what we're all thinking the instant we see that equation.

[@zat5176]

Total Slavic explanation literally boosted my math knowledges

[@vaishnavikhare2879]

Dr Eswaran from India has proved it!

[@star_ms]

No

[@SonnyBubba]

He claimed to have proved it in 2016, and the rules say it must go through at least two years of peer review. As of September 2024, the prize has not been awarded.

[@AureliusR]

I love his accent. It give the math a bit of mystery and exoticism.

[@olafpayne6562]

Watching this I felt like I had suddenly seen through to the other side of the curtain. I could feel my brain grasp this concept but then I started to feel nauseous.

[@KaranSharma-fv6kz]

Just saw this after watching the video for the 10 th time! At 7:20, for s = 2, answer is pi^2/6 not pi/6. Love these vids!

[@Bobskilintopia]

He has beautiful writing.

[@marcinkaczmarek6156]

I opt for Walter Lewin in that matter. I've developed my 'mathematical' writing style by mimicking what i saw at his famous physics course.
