he was so alienated, ultimately took its toll on him both mentally and physically. The English winters and his low-energy vegetarian diet had a detrimental effect on his already frail health and in 1917 he was hospitalised. Eventually, Ramanujan also succumbed to bouts of depression and even attempted suicide at one time. By late 1918 his health had improved slightly and he returned to India in 1919. But his health failed again, and he died at the age of 33. His wife Janaki, who lived lonely years during his stay at London, joined him in Madras on his return and nursed him till his untimely death on April 26, 1920. Those who are mathematically inclined might find this quite interesting A remarkable mathematical formula that resulted from the Hardy-Ramanujan collaboration relates to the ‘partition of a positive integer (a non-fraction number) which says that p(n) = 5 which means that the number n can be expressed as five different summations of positive numbers, regardless of order. For example, p(4) = 5 because the number 4 can be expressed or partitioned in five different ways: 1+1+1+1, 1+1+2, 2+2, 1+3, or 4 While this problem was originally studied by the pioneering mathematician and physicist Euler, Ramanujan and Hardy with an explicit formula that could calculate the partitions for any integer. 11
