Ramanujan also worked on the properties of prime numbers, including the distribution of prime numbers and the properties of prime number sequences. His work on this topic led to significant advances in cryptography and coding theory.

In 1907, Ramanujan began to send his mathematical work to prominent mathematicians in India and abroad, hoping to get feedback and recognition. One of the mathematicians who received Ramanujan’s work was Professor M. T. Narayana Iyer, who was impressed by Ramanujan’s talent and encouraged him to continue working on mathematics.

One of Ramanujan’s most famous contributions is the development of the theory of partitions, which involves finding the number of ways to express a positive integer as a sum of positive integers. This theory has far-reaching implications in many areas of mathematics and computer science.

Ramanujan’s education began at a local school, where he excelled in mathematics. However, his family’s financial situation made it difficult for him to pursue higher education. Despite these challenges, Ramanujan continued to study mathematics on his own, devouring books from the local library and working on problems that interested him.

In 1919, Ramanujan returned to India, where he continued to work on mathematics despite his poor health. He died on April 26, 1920, at the age of 32, leaving behind a legacy that would inspire generations of mathematicians.
