Content: E. V. Ramasamy, popularly addressed as Periyar or ‘The Great One’, laid the ideological foundations of modern Tamil politics and social life

• 
  Ramanujan was born on 22nd December 1887 in a village some Erode (400 km from Chennai, then known as Madras). He was passionate about mathematics from a very young age.
  
• 
  In India, December 22nd is celebrated as National Mathematics Day in the memory of Srinivasa Ramanujan.
  
• 
  The famous British mathematician Godfrey Harold Hardy recognised his talent in 1913. It was a turning point in his life. Ramanujan went to Cambridge, on Godfrey Harold Hardy’s invitation.
  
• 
  Ramanujam made substantial contributions to the analytical theory of numbers and worked on elliptic functions. He also worked on the partition of the whole number, hypo geometric series and Euler's constant.
  
• 
  His papers were published in English and European journals, and in 1918 he was elected to the Royal Society of London.
  
• 
  He died on April 26th, 1920, at the age of 32, just after returning to India after a long illness.
  

• 
  Ramanujan was born in 1887 in Erode, Tamil Nadu (then Madras Presidency) in an Iyengar Brahmin family.
  
• 
  At age 12, despite lacking a formal education, he had excelled at trigonometry and developed many theorems by himself.
  
• 
  Living in dire poverty, Ramanujan then pursued independent research in mathematics.
  
• 
  In 1914, Ramanujan arrived in Britain who worked with GH Hardy and in 1917, Ramanujan was elected to be a member of the London Mathematical Society.
  
• 
  His work in the number theory is especially regarded. He was recognised for his mastery of continued fractions, and had worked out the Riemann series, elliptic integrals, hypergeometric series, and the functional equations of the zeta function
  
• 
  Ramanujan could not get accustomed to the England’s diet, and returned to India in 1919. Ramanujan’s health continued to deteriorate, and he died in 1920 at the age of 32.
  
• 
  The Man Who Knew Infinity (2015) was a biopic on the mathematician.
  

• 
  Srinivasa Ramanujan was one of India's greatest mathematical geniuses.
  
• 
  He made substantial contributions to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series.
  
• 
  Ramanujan was shown how to solve cubic equations in 1902 and he went on to find his own method to solve the quartic.
  
• 
  He investigated the series ∑(1/n) and calculated Euler's constant to 15 decimal places.
  
• 
  He began to study the Bernoulli numbers, although this was entirely his own independent discovery.
  
• 
  He worked on Hyper-geometric series and investigated relations between integrals and series.
  
• 
  After publication of a brilliant research paper on Bernoulli numbers in 1911 in the Journal of the Indian Mathematical Society he gained recognition for his work.
  
• 
  Ramanujan worked out the Riemann series, the elliptic integrals, hypergeometric series and functional equations of the zeta function.
  
• 
  Ramanujan left a number of unpublished notebooks filled with theorems that mathematicians have continued to study.
  

The ICTP Ramanujan Prize for Young Mathematicians from Developing Countries is a mathematics prize awarded annually by the International Centre for Theoretical Physics and named after the mathematician Srinivasa Ramanujan

SASTRA RAMANUJAN PRIZE

The SASTRA Ramanujan Prize, founded by Shanmugha Arts, Science, Technology & Research Academy (SASTRA) located near Kumbakonam, India, Srinivasa Ramanujan's hometown, is awarded every year to a young mathematician judged to have done outstanding work in Ramanujan's fields of interest.

HARDY–RAMANUJAN NUMBER

The number 1729 is known as the Hardy–Ramanujan number after a famous visit by Hardy to see Ramanujan at a hospital.
