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."

This has been the simplest explanation of complex numbers, ever.

@TheVivi13 4 года назад

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 3 года назад

@@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 2 года назад

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 2 года назад

@@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).

Actually a far better way is to think 'which representation, when squared, leads to -1. let's call it √-1. -1 is, also, a 1 oriented to 180°. if you multiply 1 by -1, it rotates it 180°. if you multiply 1 by √-1, it will rotate 90°. multiply again, it will rotate 180°. ' this has broad use, for instance, in electrical circuits and electrical engineering. moreover, one can easily see the relation with sines and cosines, Euler formula etc.

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.

Goyathlay Amedeo thank you makes sense

@nileshjambhekar7699 9 лет назад

Yes but that is a direct contradiction. This video is based on the riemann zeta function which says that zeta(-1)=-1/12. They showed it to you via "floozy" math but it's a serious result in math. I don't claim to understand what it means, but it is what it is.

Extremely interesting. I've heard of the Riemann Hypothesis but never knew what it was until now.

Love Edward Frenkel's accent. And I respect him even more than before, after listening to his episode on The Numberphile Podcast.

@moamenabdelkawy5718 4 года назад

Incredible explanation. Pure gold. Videos like this keep me from uninstalling RU-vid.

@sriram828 9 лет назад

I want to really thank Numberphile for teaching me about Riemann Hypothesis clearly because I had struggled very much to understand this problem since when i learnt about the Milllennium problems. Thank you so much for describing briefly about Riemann Hypothesis

I love it the video says "keep watching" when our old friend from -1/12 videos appears

At 7:20 the video shows the calculator returning a value of pi/6 for when 2 is the input of the function, but it says earlier in the video that the value is pi squared over 6

@numberphile 10 лет назад

sorry

@CRGreathouse 10 лет назад

pi^2 / 6 is correct. The special effects are cool, but take them with a grain of salt!

@michaeldunlap111 7 лет назад

Very interesting. I'm currently studying Complex Analysis right now. Since I found it so similar to Vector Calculus, I'm constantly going back to it to find the corresponding arithmetic operations between the two. I'm excited to find out that my current studies are approaching the Riemann Zeta function, and that it plays an important role in the distribution of prime numbers. Thank you for your video!

Thanks sir, for explaining so beautifully about zeta function. Simple and eloquent.

@pooly666 7 лет назад

If you were that smart, you wouldn't care about money, so you wouldn't attempt it, or just for fun, just like this russian guy who refused the 1M $ prize on one of this problem . ;) no hate.

@pooly666 7 лет назад

***** i never saw that, but come on ... that is too obvious. Even if your comment is pretty well placed.

@mitica7914 7 лет назад

Oh Yeahh Really i domt think u can call "too obvious" he didnt mention anything about that, i mean could be but i dont know where did you get it from his comment

Not a blink actually, he simply roll his eyes downside creating the illusion of blinking. He never blinks until disproven.

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.

@Romenadan 10 лет назад

I loved the explanation of real, imaginary, and complex numbers in this video (~ 4:40-7:10). If it was taught to me this way in school I would have actually understood it!

@bkzlab 9 лет назад

@JJ-uj1wi 5 месяцев назад

I only just came across this video by recommendation thinking Im only gonna watch a few min to get the idea and move on. But I ended up watching the full video because the Theorem and the way professor explains it are so fascinating!

@babelbabel2419 Год назад

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.

@Bobskilintopia 10 лет назад

@marcinkaczmarek6156 10 лет назад

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.

@villanelo1987 10 лет назад

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 10 лет назад

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 10 лет назад

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

@Darwin226 10 лет назад

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

@kylobite 10 лет назад

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 10 лет назад

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

@r6854 4 года назад

Thank you Brady for doing a piece on Riemann hypothesis. I have been waiting for this for a while.

@matejalmasi6533 3 года назад

It all sounds esoteric. A bit later: So we connect it to distribution of primes... I know he wanted to point out the significance, because we all somehow care about the primes (computer security...). But it made me smile :)

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

@nixonkutz3018 4 года назад

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!
