Pubblicità

Srinivasa Aiyangar Ramanujan è stato un matematico indiano.

Bambino prodigio, imparò la matematica in gran parte da autodidatta. Lavorò principalmente sulla teoria analitica dei numeri ed è noto per molte formule di sommatorie che coinvolgono costanti come π, numeri primi e la funzione di partizione. Frequentemente le sue formule furono enunciate senza dimostrazione e solo in seguito si rivelarono corrette. I suoi risultati hanno ispirato un gran numero di ricerche matematiche successive.

Nel 1997 fu lanciato il Ramanujan Journal per la pubblicazione di lavori "in aree della matematica influenzate da Ramanujan".

Frasi Srinivasa Ramanujan

„Sir, an equation has no meaning for me unless it expresses a thought of GOD“

—  Srinivasa Ramanujan
Context: Sir, an equation has no meaning for me unless it expresses a thought of GOD. Statement to a friend<!-- perhaps Shiyali Ramamrita Ranganathan himself — unable to verify this as yet — online renditions of the quote and this book do not provide sufficient clarity of citation. ~ Kalki -->, quoted in Ramanujan, the Man and the Mathematician (1967) by Shiyali Ramamrita Ranganathan, p. 88 <!-- Asia Publishing House Bombay --> Variant: An equation means nothing to me unless it expresses a thought of God.

„I beg to introduce myself to you as a clerk in the Accounts Department of the Port Trust Office at Madras... I have 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".... 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 that you 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 expressons 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...“
