A thought of God

``An equation for me has no meaning unless it expresses a thought of God.’’

A thought of a 7 year old

A thought of a 7 year old

``If no fruits are divided among no one, will each still get one? Is zero divided by zero is also one?”

Books Ramanujan studied

• S.L. Loney’s Trigonometry (1893). Ramanujan mastered it when he was 13.

• A Synopsis of Elementary Results in Pure and Applied Mathematics by George Schoobridge Carr. Ramanujan read this synopsis around 1903.

Failing in F.A.

• Ramanujan joined the Government college at Kumbakonam. He failed his F.A. exams miserably. (1904-1905)

• He then joined Pachaippa’s college at Madras where he would fail again on his F.A. exams. On his physiology exam, he would write: `` Sir, this is my undigested part of the Digestion chapter”.(1906-1907)

F.A. Grades

The Port Trust Clerical JobSir,

I understand there is a clerkship vacant in your office, and I beg to apply for the same. I have passed the matriculation examination and studied up to the F.A. but was prevented from pursuing my studies further owing to several outward circumstances. I have, however, been devoting all my time to mathematics and developing the subject. I can say I am quite confident I can do justice to my work if I am appointed to the post. I therefore beg to request that you will be good enough to confer the appointment on me.

I beg to remain,9th february 1912 Sir,

Your most obedient servant,S. Ramanujan.

• Her sister would lose her eye as a child, when Hardy, playing carelessly with a cricket bat, struck her; she has to wear a glass eye for the rest of her life.

Hardy and God

• Once, as he and a clergy mean walked in the fog, they saw a boy with a string and stick. The clergyman likened God’s presence to a kite, felt but unseen. In the fog he told young Hardy, ``you cannot see the kite flying, but you feel the pull of the string.’’ But in the fog, Hardy thought, there is no wind and no kite can fly.
