A sum by Ramanujan

I read somewhere that Ramanujan said that



Does anyone know how this came about or where I might go to read more about it? Thanks

Re: A sum by Ramanujan

Hi identity;

Read that too, it kept Indian mathematicians from taking him seriously. That is only true in Ramanujan Summation. There is also Cesaro Sums amd Borel summation, each is a different approach to summing a divergent series. They are sometimes useful in Physics.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: A sum by Ramanujan

Hi identity;

Yes, he was. The whole story is interesting. Hardy once said that he rated himself 25 and Littlewood a 30 and Hilbert 80 but Ramanujan 100. When you consider that Hardy ,Littlewood and Hilbert were considered among the best in the world, then you understand Ramanujan a little better.
