Ramanujan was literally self-educated and he came up with some superb formulas and more. I would say that among the recent 500 years of geniuses Ramanujan definitely deserves a place. That said, computer science of today use many of Ramanujan's formulas because they not only are brilliant, but computers love them with only a few tweaks. What is that? A guy, from India, self-taught in math, provided results that benefits all of the globe today (with just some small tweaks), isn't that GREAT? I am amazed, to say the least.

Definitely not -- but my knowledge about Ramanujan begun by a beginner's class of computer science, so I cannot 100% agree with you on the "western" statement ... except the class was about numerical computing and thus not mathematician-only
They definitely do a lot. I've seen westerners straight up deny Ramanujan and said he made up stuff on his own this lacking proofs. Incredibly ignorant, but I'd have to say none of those westerners seem quite educated on higher mathematics let alone basic math. l@
At 03:14 you say "no one knows how he actually got the formula". GH Hardy has stated that when he asked the same question to Ramanujan, he replied "God talks to me". This dialogue is also shown in the movie 'The man who knew infinity'.
@@koushikmediga8397 Actually not. It did happen that her deity goddess came in his dreams and told him the formulas, and then his work was just to prove them!!
@@adityaagarwal636 yeah that's that's he meant. Our mind works like that. Many scientists have had encounters like that. Where they get answers just after a sleep or having written something in their notebook during sleep. There are accounts for that. Ramanujan just attributed that to his godess but it was he himself who was actually doing it subconsciously. Our subconscious mind is surprisingly more productive when we focus on it
The pi formula that you mentioned which was discovered by Leibnitz was actually discovered by an Indian mathematician named Madhava about 300 years before Leibnitz was even born!
Euler, Gauss, Ramanujan, Jacobi are the true geniuses who spit out concepts after concepts and formulas that are the basic of every math today. Black holes are now being explained by Ramanujan’s mock theta functions discovered by him 80+ years ago, while on his deathbed and wanted to share it right away via a letter to Hardy because he knew it was so important to share. This is quite unexplainable how he could have seen the importance of mock theta functions that early. I do not recall any science genius or even any prominent scientist of having written down a piece of complex math that was applicable to an application that would only be discovered so far into the future. Basically, Ramanujan had the math ready to be put to use to explain a physical discovery that happened way into his future? This is superhuman. No other mathematician ,past or present , was this superhuman. It is quite unexplainable and bizarre actually.
Look forward to seeing a new Riemann Hypothesis video by you. I believe it will be fantastic. Your insights on such a profound and challenging topic would be incredibly valuable. I've always admired your ability to explain complex mathematical concepts clearly and engagingly. A new video on the Riemann Hypothesis would be an excellent update to your content, and I'm sure many others would benefit from and enjoy it as well. Please do it!
Ramanujan himself did not derive it from first principles..it was given to him in a dream by the God he believed in. The structure of Benzene which had evaded scientists was revealed to Kekule in a dream. God does miracles thru his chosen subjects . No one can explain how a simple Indian from those days who had no mathematical background in university could solve so many theorems, even attempted to solve Fermat's last theorem, thus came up with the magic number 1729 as the smallest number that can be expressed as sum of two cubes in two different ways...simply amazing

Bullshit. Most great mathematicians in history ate meat. Not saying that eating meat is a good to thing, in fact factory farming is very cruel and the meat industry is destroying the planet, but eating meat is not detrimental to mathematical ability.
Its called the Madhava-Leibniz series. Madhava of Sangamagrama is still not recognized for his work. In a way, rightly so, because of very little historical evidence.
Leibniz did not actually come up with that formula you talk about at 1:41, it is miscredited to him. Check out the documentary "The History of Maths" on Netflix it talks about it
Will you talk about Ramanujan's almost integer numbers at some point this week? For me that's his works that appeals the most to my imagination. Especially considering he derived them way before any type of serious (digital) calculator was available.
The formula for pi you attribute to leibnitz was originally discovered by Sankara , an Indian mathematician some 200 years earlier, leibnitz name still figures in math history books ‘cos - white man invented everything.. great ..
0:22 He actually said that his deity goddess came in his dreams to tell all those unproved formulas to him, and then he just tried to prove all these afterwards. That's why there are still no proves to many of his formulas, but all of them work....
What is that device on your desk behind you? And are those markers or tapes to the right? Can't make them out, just curious - thanks for your videos !!!!
Hi, this is very informative. I have seen formulae by Ramanujan and the Chudnovsky brothers, but how do these compare in accuracy with the actual value of pi?
11-33-55 easy to remember. Last three divided by first three is 355/113 = 3.1415929.... and is pi to 6 decimal places or 27 parts in 100 million. Not as accurate as Ramanujan's formula which is 7.6 parts in 100 million, but easier to remember. So only estimate the circumference of the earth to about 3.5 meters. e can be estimate with 335588/123456 but this is only about 160 parts in 100 million Just in case you forget your slide rule.
+WatchingTokyo No, the document he sent to Cambridge had already deduced that. So it unlikely Grime would use that, plus it has already been done a thousand and one times.
+twertygo If you want to see controversy you just need to check the comment section of some of Numberphile's videos, like 1+2+3+ ... = -1/12, problems with zero, infinity paradoxes.
Hilbert was a normal human who made sense. Godel was a guy who was rational. Einstein was a regular man who understood logic. Euler was a reasonable husband and father. Galois was a talented bachelor. Ramanujan.. Compared to them, he was like an insane alien genius who must have obtained non-finite intuition from spiritual beings. Screw what Hardy said about him being 100 and Hilbert being an 80, they are all 1's and he's still at the limit of 100 on that scale. We can't figure out where he was because nothing he figured out was anywhere near normal. Go look at his work for yourself. It was strange and different. It wasn't even proofs or restricted to logic systems. He had crazy intuition results and approximations which are insanely accurate yet not precisely the function, so all the more curious how he developed them.
He was a genius with a great intuition similar to the likes of Gauss but I think it was the lack of formal training and the lack of guidance in formal research which contributed towards his early work being more based on intuitions.
I have a dim sense that Leibnitz's infinite sum to approximate pi is doing, in essence, what Archimedes was doing with his calculation of ever-more-sided inscribed and circumscribed polygons. But I am as far from being a mathematician as it is possible to be. Perhaps someone can explain if this in any way correct?
-Take the first three odd integers: 1,3,5 -Double them thusly: 113355 -Divide the last three by the first three thusly: 355/113 There ya go, Pi accurate to 6 decimal places!
+ThePlatinumPenguinHD - 4:20 is 260 seconds. 260/π/e = 30.4. 30.4 years is the age Ramanujan was when he was admitted to the Nursing Hostel in Cambridge. I assume that's the coincidence you're referring to.
Pi is equal to 3.142696805... square root 2 times 2.2222222... if you have circle with radius equal to square root 2x4.5 the circumference is 40 exactly. The area is equal to the square root of 16,200
In Ramanujan's day, there were already *far* better formulas for π than Leibnitz' aesthetically beautiful, but computationally atrocious formula. [And actually, by using some convergence acceleration techniques, this can actually be turned into a (barely) useful computational tool.] John Machin's formula of 1706, ¼π = 4tan⁻¹(⅕) - tan⁻¹(1/239) using the Taylor series for arctan was, for instance, far superior. And this formula was further improved in 1789 by Jurij Vega. These are the proper objects of comparison for rating Ramanujan's formula, which was still a vast improvement, even over these. Secondly, I would like to have heard what if anything has been done to ferret out Ramanujan's method of arriving at his formula. Since it has been improved on (by the Chudnovski's), and is used today to compute π, there surely must at least be a proof of its validity? Fred
But how did he get to the formula ?? I mean it's quite weird to find such result in the first of the 20th century . Only one possibilty is left , which is he was seeing maths far more differently than anybody.
Profesor, i have a doubt. Ok, ramanujan's formula is incredible, but it uses √8 which also has to be aproximated, right? What is the point of having an approximation for a irrational number using an irrational number? Like, is it computationaly easier to estimate √8 than pi??
that's all good and well but WHY does this formula work; what's the theory behind it? That's why i came here. Found the formula elsewhere, can't make sense of the wiki page related to it so i was hoping for an explanation here :-/
This is my formula for approximating pi... pi ≃ 31415926535/10000000000... it's good up to 10 decimal places... Am I smarter than Ramanujan? I think so.
Ramanujan's formula was an infinite sum that would have resulted in exactly pi. The bit that was to 6 decimal places was just the first term. Ramanujan's first two terms would have beaten your approximation.
When something cracks it usually has a random direction pattern. And the universe should have cracked that way. Usually random direction of Big Bang. And why because if you put things together and keep on building then when something crash it takes time in different directions. Though symmetry is a localised pattern of numbers. Pi is about symmetry rather than random. Whenever you need symmetry which is supposed to be more stable you have to use Pi. Even if you take distant galaxies the spectrum of them gives the symmetry elements of the galaxy. Almost 90% are hidden space of the random. Light can come only from electrons transitions of nucleus disstable. That too relative.
When I see these formulae by Ramanujan and the like (and there have been few like him), I wonder how did they arrive at it, then I wonder if the presenter or professor (from my university days) is pulling some sort of prank on us, much like an April Fool's prank. Finally I realize, to paraphrase Hardy, they must be real equalities and formulae because "nobody" would have the imagination to invent them. [Actually, there have been a few such imaginative mathematical pranks, such as Martin Gardner's April Fool's prank during the mid-70s, and published in Sci.Am.]
There is only one number that consecutively repeats itself nine times in the first one and a half billion digits of pi. What is the 10 digit number and where does it begin in the sequence?

Leibniz did not actually come up with that formula you talk about at 1:41, it is miscredited to him. Check out the documentary "The History of Maths" on Netflix it talks about it
Will you talk about Ramanujan's almost integer numbers at some point this week? For me that's his works that appeals the most to my imagination. Especially considering he derived them way before any type of serious (digital) calculator was available.
Love that the prime number generator is still on the desk
I was going to make a joke about forests, but why wood I?
lol?
i'm you didn't because it would have been irrelevant
Ugh gross😂😂😂 jfbfjsbsvsjwvvaj
Generic Internetter
You didnt understand the joke?
But you made it....
God I love your explanation, I've been watching your videos all day long for goodness
The formula for pi you attribute to leibnitz was originally discovered by Sankara , an Indian mathematician some 200 years earlier, leibnitz name still figures in math history books ‘cos - white man invented everything.. great ..
0:22 He actually said that his deity goddess came in his dreams to tell all those unproved formulas to him, and then he just tried to prove all these afterwards. That's why there are still no proves to many of his formulas, but all of them work....
What is that device on your desk behind you? And are those markers or tapes to the right? Can't make them out, just curious - thanks for your videos !!!!
Hi, this is very informative. I have seen formulae by Ramanujan and the Chudnovsky brothers, but how do these compare in accuracy with the actual value of pi?
There is no actual value of pi.....it goes on and on to infinity, just like the number e
@@ernst9100 Noted Sir. But generally these two would align with the actual irrational value to what extent?
Math geeks complaining about too much mail?
Get your calculators ready, the _-1/12_ series is coming.
KEEP IT COMING! I'M LOVING IT!
Love these!!
"Everyone loves pi!" Tell that to vihart :)
Do you know if he really did write sqrt(8) instead of 2sqrt(2)? Would really like to know!! Good video :)
11-33-55 easy to remember. Last three divided by first three is 355/113 = 3.1415929.... and is pi to 6 decimal places or 27 parts in 100 million. Not as accurate as Ramanujan's formula which is 7.6 parts in 100 million, but easier to remember. So only estimate the circumference of the earth to about 3.5 meters.
e can be estimate with 335588/123456 but this is only about 160 parts in 100 million
Just in case you forget your slide rule.
looking forward to the next video since I don't know how math is going to be controversial :)
Maybe something related to 1 + 2 + 3 + ... = - 1/12
+WatchingTokyo No, the document he sent to Cambridge had already deduced that. So it unlikely Grime would use that, plus it has already been done a thousand and one times.
+twertygo If you want to see controversy you just need to check the comment section of some of Numberphile's videos, like 1+2+3+ ... = -1/12, problems with zero, infinity paradoxes.
+IceNoob88 But it's all just logical and makes sense!
+twertygo Then jump into some math forum and ask if √4 = +2 or -2, or just the +2 ;)
(On second thought: _don't_ :P )
Can you please post your resources!! I would love to read more and where you got your info from!!
awesome!
Another great video!
Hilbert was a normal human who made sense.
Godel was a guy who was rational.
Einstein was a regular man who understood logic.
Euler was a reasonable husband and father.
Galois was a talented bachelor.
Ramanujan.. Compared to them, he was like an insane alien genius who must have obtained non-finite intuition from spiritual beings.
Screw what Hardy said about him being 100 and Hilbert being an 80, they are all 1's and he's still at the limit of 100 on that scale. We can't figure out where he was because nothing he figured out was anywhere near normal. Go look at his work for yourself. It was strange and different. It wasn't even proofs or restricted to logic systems. He had crazy intuition results and approximations which are insanely accurate yet not precisely the function, so all the more curious how he developed them.
He was a genius with a great intuition similar to the likes of Gauss but I think it was the lack of formal training and the lack of guidance in formal research which contributed towards his early work being more based on intuitions.
I have a dim sense that Leibnitz's infinite sum to approximate pi is doing, in essence, what Archimedes was doing with his calculation of ever-more-sided inscribed and circumscribed polygons. But I am as far from being a mathematician as it is possible to be. Perhaps someone can explain if this in any way correct?
I appreciated the energy and content
Gosh such a smart fellow
3:53 "But, everyone loves pi"
No. #taumasterrace
tau>pi
+Zardo Dhieldor And 7>tau, what's your point? ;-)
+Zardo Dhieldor that's literally true!
+palmomki Not only literally though! :)
+Zardo Dhieldor Pi gets you to the other side of the circle, tau gets you nowhere.
From his behaviour I can say that he is one of those genius away from world affairs.🙁
Absolutely right man
Is that the prime number generator in the background?
Always love Jame Grime's videos!!
-Take the first three odd integers: 1,3,5
-Double them thusly: 113355
-Divide the last three by the first three thusly: 355/113
There ya go, Pi accurate to 6 decimal places!
logic behind this?
@@doserastalmi I think it's more of an intuition. And he was just offering a simple method to remember and apply it
4:20 video length... Coincidence?
+ThePlatinumPenguinHD - 4:20 is 260 seconds. 260/π/e = 30.4. 30.4 years is the age Ramanujan was when he was admitted to the Nursing Hostel in Cambridge. I assume that's the coincidence you're referring to.
+Keira Churchill WOW!
In phone it is 4:21 ;( But I believe it is 4:20
Here is a sobering thought I wonder how many 420 worshipers know that is also Hitler's birthday?
It’s because my dude James Grimes smokes the dutty stinky loud on the RE-GU-LAR my friends
Pi is equal to 3.142696805... square root 2 times 2.2222222... if you have circle with radius equal to square root 2x4.5 the circumference is 40 exactly. The area is equal to the square root of 16,200
I love Nottingham accent
You could be a good teacher.you explains complex things very understandable and easily comprehensible
In Ramanujan's day, there were already *far* better formulas for π than Leibnitz' aesthetically beautiful, but computationally atrocious formula.
[And actually, by using some convergence acceleration techniques, this can actually be turned into a (barely) useful computational tool.]
John Machin's formula of 1706,
¼π = 4tan⁻¹(⅕) - tan⁻¹(1/239)
using the Taylor series for arctan was, for instance, far superior. And this formula was further improved in 1789 by Jurij Vega.
These are the proper objects of comparison for rating Ramanujan's formula, which was still a vast improvement, even over these.
Secondly, I would like to have heard what if anything has been done to ferret out Ramanujan's method of arriving at his formula.
Since it has been improved on (by the Chudnovski's), and is used today to compute π, there surely must at least be a proof of its validity?
Fred
But how did he get to the formula ?? I mean it's quite weird to find such result in the first of the 20th century . Only one possibilty is left , which is he was seeing maths far more differently than anybody.
My brother who is engineering topper says physicists are afraid of none but Mathematicians.
A new subscriber! Thanks
how about a video on the roots of 200, 64, 90, and 30 and their relationship to each other.
Yay! When I saw your face, I immediately remembered Numberphile.
Profesor, i have a doubt. Ok, ramanujan's formula is incredible, but it uses √8 which also has to be aproximated, right? What is the point of having an approximation for a irrational number using an irrational number? Like, is it computationaly easier to estimate √8 than pi??
that's all good and well but WHY does this formula work; what's the theory behind it? That's why i came here. Found the formula elsewhere, can't make sense of the wiki page related to it so i was hoping for an explanation here :-/
How about dividing 16 by 113 plus 3, that will also give Pi with six correct digits. With help of my HP-35s calculator.
This is my formula for approximating pi... pi ≃ 31415926535/10000000000... it's good up to 10 decimal places... Am I smarter than Ramanujan? I think so.
Definitely
No
Do you know How to solve Paratitions?
Oh yeah you are
Ramanujan's formula was an infinite sum that would have resulted in exactly pi. The bit that was to 6 decimal places was just the first term. Ramanujan's first two terms would have beaten your approximation.
Loving this series.. Keep it up
When something cracks it usually has a random direction pattern. And the universe should have cracked that way. Usually random direction of Big Bang. And why because if you put things together and keep on building then when something crash it takes time in different directions. Though symmetry is a localised pattern of numbers. Pi is about symmetry rather than random. Whenever you need symmetry which is supposed to be more stable you have to use Pi. Even if you take distant galaxies the spectrum of them gives the symmetry elements of the galaxy. Almost 90% are hidden space of the random. Light can come only from electrons transitions of nucleus disstable. That too relative.
Ancient Indian history shows many evidences where many mathematical formulae were already being used.
Can anyone please explain how Ramanujan derived the formula. I know he addressed it but I didn't fully understand.
ramanujan and blackhole..pls make a video on it too
When I see these formulae by Ramanujan and the like (and there have been few like him), I wonder how did they arrive at it, then I wonder if the presenter or professor (from my university days) is pulling some sort of prank on us, much like an April Fool's prank. Finally I realize, to paraphrase Hardy, they must be real equalities and formulae because "nobody" would have the imagination to invent them. [Actually, there have been a few such imaginative mathematical pranks, such as Martin Gardner's April Fool's prank during the mid-70s, and published in Sci.Am.]
In fact, G.H.Hardy thought it was a prank by Littlewood when he got those papers from Ramanujan! (See: ruclips.net/video/ay1RCfQkrWQ/видео.html)
So what is applications of these pi formulas? Don't we already know pi to be 22/7 (or is that also an approximation formula)?
There is only one number that consecutively repeats itself nine times in the first one and a half billion digits of pi. What is the 10 digit number and where does it begin in the sequence?
Tell me all the pi formulas used to make tires, cans, china, pistons, windows,pizzas, etc? They all use 6 numbers.
How did Ramanujan and Leibniz come up with those formulae?
son muy buenos tus vídeos
He said "The devi(goddess) bleeds maths in me",
which is beyond our understanding.
finally!!!! The Pi equation is shown!!
James Grime seems very excited about this movie.
I wouldn't have such high expectations.I am praying they don't add a dancing scene like every other movie about indians.
Haha!!! Right, they make everything Indian Bollywood!
+Iheb Chagra For some reason every Bollywood movie I have ever watched had exactly six, evenly spaced dance scenes, and they were all cancer. Just an observation.
bro first one is madhav formulae
Ramanujan said he was viewing colourful pictures when he was generating formulas. After he came to Britain his supplier refused to follow him that is why he died
