Srinivasa Ramanujan (1887–1920) was an Indian mathematician who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Largely self-taught, Ramanujan's early work was marked by groundbreaking theorems that he discovered intuitively, without formal proofs. His work, though largely unknown outside of India, was eventually recognized by British mathematician G.H. Hardy, who invited him to Cambridge University. There, Ramanujan collaborated with Hardy, producing influential results in areas such as partition theory and the properties of prime numbers. Despite struggling with health issues and the challenges of adapting to life in England, Ramanujan's genius shone brightly. He produced a wealth of original work, including the famous Ramanujan primes and his highly accurate approximations for pi. Ramanujan's legacy continues to influence mathematics today, with numerous formulas and concepts bearing his name, and he remains an iconic figure in the history of mathematics.
