Tributes to The Mathematical Wizard


A short but remarkable life. That’s probably the best way of describing the life and times of Mr.Srinivasa Ramanujan. Mr Ramanujan is a figure that needs no introduction. His contribution to mathematics is indeed pathbreaking and his genius, mesmerising. 

Today, as we celebrate his 131st birth anniversary, it fills me with immense pride and awe to just observe the kind of contribution he made to the modern mathematics in a life that was cruelly cut short at the young age of 32. 

It is really a marvel that Mr Ramanujan was able to scale the heights of academic world with no formal training. It was purely his zeal and passion for the subject that brought him such widespread glory. Ramanujan has always been a figure whose life has intrigued me and inspired me to a great extent. I’ve happened to read a lot of publications on him and one thing that they all mentioned in common was about the gem of a character he possessed. Described as a shy yet pleasant personality, Ramanujan was a one of a kind gentleman. 

A lot has been spoken and documented about the works of Mr Ramanujan. His contributions to mathematical analysis, number theory, infinite series are things that we all are aware of. However, I want to highlight something that in my opinion made Ramanujan the success story that he is.

 

It was while reading up on his works that I came across this gem of a letter which marks the first interaction between Ramanujan and his mentor, British mathematician Mr. G. H. Hardy. The duo would later go on to forge a great friendship and a great professional bonding to give some of the most iconic mathematical works to the world.  The letter reads as follows:

Dear Sir,

I beg to introduce myself to you as a clerk in the Accounts Department of the Port Trust Office at Madras on a salary of only £20 per annum. I am now about 23 years of age. I have had no University education but I have undergone the ordinary school course. After leaving school I have been employing the spare time at my disposal to work at Mathematics. I have not trodden through the conventional regular course which is followed in a University course, but I am striking out a new path for myself. I have made a special investigation of divergent series in general and the results I get are termed by the local mathematicians as ‘startling’.

Just as in elementary mathematics you give a meaning to   when   is negative and fractional to conform to the law which holds when   is a positive integer, similarly the whole of my investigations proceed on giving a meaning to Eulerian Second Integral for all values of   . My friends who have gone through the regular course of University education tell me that   is true only when   is positive. They say that this integral relation is not true when   is negative. Supposing this is true only for positive values of   and also supposing the definition   to be universally true, I have given meanings to these integrals and under the conditions I state the integral is true for all values of   negative and fractional. My whole investigations are based upon this and I have been developing this to a remarkable extent so much so that the local mathematicians are not able to understand me in my higher flights.

Very recently I came across a tract published by you styled Orders of Infinity in page 36 of which I find a statement. that no definite expression has been as yet found for the number of prime numbers less than any given number. I have found an expression which very nearly approximates to the real result, the error being negligible. I would request you to go through the enclosed papers. Being poor, if you are convinced that there is anything of value I would like to have my theorems published. I have not given the actual investigations nor the expressions that I get but I have indicated the lines on which I proceed. Being inexperienced I would very highly value any advice you give me. Requesting to be excused for the trouble I give you.

I remain, Dear Sir, Yours truly,

S. Ramanujan

 

The most remarkable things that I found in this letter was the precision, confidence and humility with which Ramanujan wrote. There is a lot that we as individuals can learn just from this letter. It is astonishing to see polite yet strong demeanour that Ramanujan displayed here. 

Probably it is this character that propelled him to such great heights.
