1. Describe the life of Srinivasa Ramanujan in India.
Answer:
Ramanujan was born in Erode in Tamilnadu on December 22,1887. From early childhood, it was evident that he was a prodigy. Senior students used to get his assistance in solving math problems. At the age of 13, he began his own research on Trigonometry. The book “Elementary Results in Pure Applied Mathematics” by George Shoobridge Carr triggered the genius in Ramanujan. He used to do problems on loose sheets and enter the results in notebooks which are now famous as “Ramanujan’s Frayed Notebooks”.

Although Ramanujan secured a first class in Mathematics in the matriculation examination and was awarded the Subramanyan Scholarship, he failed twice in his first year arts examination in college as he neglected other subjects such as History, English and Physiology. He searched for job for food and papers to do calculations. The Director of Madras Port Trust gave a clerical job to Ramanujan on a monthly salary of Rupees 25.

2. Narrate the association of Ramanujan with G.H. Hardy.
Answer:
Ramanujan sent a letter to the great Mathematician G.H. Hardy of Cambridge University, in which he set out 120 theorems and formulae which included the Reimann Series. Hardy and his colleague Littlewood realized that they had discovered a rare mathematical genius.

They invited him to Britain.Despite the cold weather and food, Ramanujan continued his research with determination in the company of Hardy and Littlewood. Hardy found an unsystematic mathematician in Ramanujan due to his lack of formal education. Ramanujan’s achievements include the Hardy-Ramanujan-Littlewood circle method in number theory.
