About Srinivasa Ramanujan

The man who knew infinity

Srinivasa Ramanujan had his interest in mathematics unlocked by a book. It wasn’t by a famous mathematician. The book was A Synopsis of Elementary Results in Pure and Applied Mathematics (1880, revised in 1886), by George Shoobridge Carr. The book consists solely of thousands of theorems, many presented without proofs, and those with proofs only have the briefest. Ramanujan encountered the book in 1903 when he was 15 years old.

Question: Lets go with the question

Answer:

Once a person asked Ramanujam that why he didn’t have any close friends.He replied that although ramanujam wanted to have close friends -nobody was up to his expectations. Then he asked how he expected his friend to be — ramanujam replied — like numbers 220 and 284!

The person got confused and asked what is the connection between friendship and these numbers! Ramanujam asked him to find the divisors of each number! With much difficulty — the person derived and listed them

220 → 1,2,4,5,10,11,20,22,44,55,110,220

284 →1,2,4,71,142,284

Ramanujam then asked the person to exclude the numbers 220 and 284 and asked the sum of the remaining divisors The person was surprised on seeing on answer:

220 → 1+2+4+5+10+11+20+22+44+55+110=284

284 →1+2+4+71+142=220

Ramanujam explained that,

An ideal friendship should be like these numbers- to complement each other, even when one is absent the other should represent the friend!
