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
Volume 3 of Ramaswami iyer’s new journal
Some Properties of Bernoulli Numbers
The Port Trust Clerical Job
Sir,
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.

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.
