aahhh just another one of Ramanujan's random identities that he divined from the minds of the gods. reading these has been a reliable way for mathematicians to humble themselves since 1900.

he often wouldn't (or wasn't able to) prove them. they were just assertions that, much more often than not, turned out to be accurate.

[Blammar]

I have read (though can't find the source) that Ramanujan had access to a black board, chalk, and just the paper in his notebooks -- no other paper.

So he did his derivations and proofs on the blackboard, and just wrote down the result in his notebook and then erased the blackboard.

He knew he didn't have room for anything else in his notebooks.

[qart]

Not a blackboard, but just a slate. Paper was too expensive for him, so he used it only to write down results.

That’s very fascinating. I guess it still is the case for many people in the world, that paper is too expensive. Whereas for many of us it’s readily available in massive, one might even say infinite, quantities.

[SamBam]

An actual, literal case (instead of a cop-out) of "a truly marvelous proof, which this margin is too narrow to contain."

[wglb]

It is talked about in his biography "The Man who Knew Infinity"

[alquemist]

How would a mere mortal could possibly divine equations like this?

There is a method behind it. The formulas are derived from the study of relatively simple ODEs, in this example f'(x) = x.f(x) + 1 and g'(x) = x.g(x) − 1. The latter was solved 100 years prior by Jacobi. While the solutions are non-trivial, they are fairly compact, accessible to a high schooler. The presentation linked from the blog is pretty good at unveiling the magic.

This is to say that, with proper guidance, the kid down the street can too become as cool as Ramanujan.

Proving statements that are known to be true requires a different skillset from coming up with true statements.

[Crazyontap]

I don't understand what you mean. He couldn't have just come up with that huge equation on the page out of thin air?

Surely there would be a method for coming up with such assertions (maybe only known to him though)

[dharma1]

"Ramanujan said that, throughout his life, he repeatedly dreamed of a Hindu goddess known as Namagiri. She presented him with complex mathematical formulas over and over, which he could then test and verify upon waking. Once such example was the infinite series for Pi:

Describing one of his many insightful math dreams, Ramanujan said:

"While asleep I had an unusual experience. There was a red screen formed by flowing blood as it were. I was observing it. Suddenly a hand began to write on the screen. I became all attention. That hand wrote a number of results in elliptic integrals. They stuck to my mind. As soon as I woke up, I committed them to writing...""

[laichzeit0]

I think this kind of explanation irritates many people for some reason. As if things just can't be that way, there must be a repeatable, reproducible recipe that someone else could follow, and if they did, they would get the same results as Ramanujan.

I think maybe because it flies in the face of everyone that claims 10x developers are not possible. Or that some people are just genetically gifted and there's nothing you could possibly do that would get you within a hundred yards of them no matter how much hard work you put in, or how good your teachers were, etc. (thinking about John von Neumann here).

It's sort of depressing to think that there's almost a different species of man amongst us. It's undeniable though.

[PartiallyTyped]

There have been quite a few such people in history. It's really humbling to know that Galois did what he did at just 20, Gödel was just a year older than me when he broke PM, Neumann could solve problems faster than what it took a person to write a program on the computer to solve the problem and the computer running.

While genetics play a huge role, nurture plays a large role as well [1].

Yes, it goes against the cult of Effort, "10000 hours of deliberate practice" and all that. But I believe you're 100% right: those at the absolute right end of the distribution are often gifted. They work hard, too, but that is akin to sharpening the knife. It is not the knife.

I'm reminded of a documentary on Tiger Woods on one of the Discovery channels where the voice over is going, "How did Tiger Woods become such a genius? Was it his family's Buddhist traditions?", and it went on to list a bunch of possible factors, all the while showing a clip of Tiger Woods playing golf with absolute perfection AT THE AGE OF FOUR! I had to laugh at the mental effort being expended to avoid the horrific conclusion that he was born with it.

[laichzeit0]

Yeah I guess that's kinda what I mean: Hard work is necessary, but it is not sufficient.

[sdenton4]

It's also the case that genius alone isn't sufficient. One also needs hard work and, as Ramanujan illustrates, access to institutions that can publish+legitimize the work.

I also find it fun to consider that the population is 7x larger today than it was in 1800, and there's generally much better access to education across the board. Around 1900 you've got a bunch of absolute giants in mathematics: Hilbert and Ramanujan, for starters, but also Riemann and Lobachevsky (whose noneuclidean geometry work was basically Einstein minus the physics). So, suppose O(5) world-changing geniuses. On raw population alone, one would expect about 35 people of similar caliber to be active today. But also mathematics as a profession, access to phd programs, etc, is many times larger per capita than it would have been in 1900. So I would personally guess that there's likely to be a couple hundred people currently active in math of a similar caliber.

[linspace]

What cult of effort are you talking about? I think usually people outside a field underestimate both the talent required and the effort. Children can be even more obsessed than adults also and be completely laser focused.

[psychoslave]

> I think this kind of explanation irritates many people for some reason. As if things just can't be that way, there must be a repeatable, reproducible recipe that someone else could follow, and if they did, they would get the same results as Ramanujan.

Oh, there is an easy recipe : just emulate the universe as it was back then and observe Ramanujan. As we know, having a recipe doesn’t mean we have the resources to implement it.

There are several movies on Ramanujan as well as biographic books. Apart from the tragic path of is life, these material also depict him not only as gifted but as a compulsively working his maths. So that’s no wonder he would even dream about it. And of course, you can model that as the result of unconscious thoughts throwing the result of problems that were fed to the mind during awaken time.

So, the magic recipe is practice, practice, and practice even more.

> I think maybe because it flies in the face of everyone that claims 10x developers are not possible.

On what metrics? The ability to be able to throw impressive "magical" code and being able to work efficiently with the rest of a team will not necessarily come together, for example.

> Or that some people are just genetically gifted and there's nothing you could possibly do that would get you within a hundred yards of them no matter how much hard work you put in, or how good your teachers were, etc.

“Be yourself; everyone else is already taken.” is generally attributed to Oscar Wilde.

Every life is genetically gifted, but not all lives encounter the environment that enables to thrives this gift – unfortunately.

Also no one is perfect. Many aspect of human life are not only dependent on how performant you are individually, so being really "too ahead" can be actually a severe handicap – at least if it doesn’t come with equal excellence into convincing other to trust you. And so depression is not something you can expect to be out of the realm of gifted evoked here.

[edgyquant]

I think it’s just the case that some people are born with intuition or better yet everyone is but some people are born with intuition that is game changing. Ramanujan had a natural intuition for infinite series as Einstein did for relativity and even though their work would have eventually been discovered one way or another I believe their intuition does give the impression they did what would have taken many people to do in a short time in comparison.

[alberto_ol]

> “Be yourself; everyone else is already taken.” is generally attributed to Oscar Wilde.

According to quoteinvestigator there is no evidence that Oscar Wilde said that

https://quoteinvestigator.com/2014/01/20/be-yourself/

[dharma1]

yes, I think this is the likely explanation - your brain processes information when you are asleep and many times you may get insights from the unconscious this way in the morning.

In addition to hard work Ramanujan was exceptionally gifted, and likely stumbled on some mental processes at an early age that gave him an edge, and spent the rest of his life perfecting them.

Real shame that he passed so early, due to a disease that would have easily been avoidable or curable today. Imagine what else he would have been able to achieve if given another 10-30 years.

[maaaaattttt]

I for one find the fact that such people existed very exciting. It means that some possible configuration of our physiology allows for amazing capabilities. Maybe nurturing has to do with it too, but the point is that it is possible.

Maybe one day (in a distant future most likely) the general population will have access to such mental prowess. This would then be another kind of singularity!

...or the 4-year-old chess prodigy, or the 5-year-old composer.

As an amateur chess player, I don't find it depressing -- although more likely I use it as an excuse. I know that there are kids out there who started out with a significantly-higher ranking within a year of playing than I will ever get to as an adult. (That said, many those same kids will eventually go on to put in tens of thousands of more hours than me.)

I guess the part that's slightly depressing is that, even if I slog and slog, and raise my ranking up by a bit, it will always feel like winning by perspiration, and not by divine inspiration. But I think it's fine for me to say "this isn't my game, I will play it so long as it's fun, but I won't ever be a genius at it."

[saghm]

I've had times when during a dream, I've heard a melody, and when I woke up, I picked up an instrument and was able to replicate the melody I heard when dreaming. If I can come up with good sounding melodies in my sleep despite being a fairly unpracticed musician, I can only imagine what geniuses in their respective fields are able to figure out unconsciously! Obviously the presentation within the above described dream is fairly dramatic, but that might just have been his mind's way of making sure he remembered it when he woke up.

Recently visited the "Ramanujan Museum" in India which showcases his original works:

* Where we could see his family goddess - Sri Namakkal Namagiri Thayaar who he credited for his works:

Another famous mathematician, Paul Erdős, took Ritalin and Benzedrine and when he stopped for a month (to win a bet), he complained like this:

"Before, when I looked at a piece of blank paper my mind was filled with ideas. Now all I see is a blank piece of paper."

[emmanueloga_]

Reminds me of TempleOS, "created by American programmer Terry A. Davis, who developed it alone over the course of a decade after a series of prophetic episodes that he later described as a revelation from God."

[shmerl]

According to him it wasn't a method, but an insight. So if you like to phrase it that way, you could say it he came up with it "out of thin air".

[Der_Einzige]

I am a strong atheist, but I have a hard time calling Ramanujan a liar when he says that god (or a god) give him his knowledge...
