Srinivasa Ramanujan - Icon Profile | Alexandria
Srinivasa Ramanujan (1887-1920) was an extraordinary Indian mathematician whose intuitive genius and profound contributions to number theory, infinite series, and mathematical analysis continue to mystify and inspire scholars today. Born into modest circumstances in Erode, Tamil Nadu, Ramanujan possessed an almost supernatural ability to perceive mathematical relationships, often arriving at complex solutions through methods that defied conventional mathematical logic.
By age 12, Ramanujan had mastered trigonometry and developed sophisticated theorems on his own. His early mathematical education was largely self-taught, primarily through studying G.S. Carr's Synopsis of Elementary Results in Pure and Applied Mathematics. This isolation from formal mathematical training perhaps contributed to his unique approach to problem-solving, which often relied on intuition and flash insights that he attributed to the goddess Namagiri.
The trajectory of mathematical history changed in 1913 when Ramanujan sent his work to G.H. Hardy at Cambridge University. Hardy, initially skeptical, soon recognized the manuscripts as the work of a mathematical genius and arranged for Ramanujan to come to England. Their subsequent collaboration produced groundbreaking results in partition theory, mock theta functions, and the properties of highly composite numbers. The famous "taxi-cab number" 1729, now known as the Hardy-Ramanujan number, emerged from a bedside conversation that perfectly encapsulated Ramanujan's extraordinary mathematical intuition.
Ramanujan's legacy extends far beyond his brief life of 32 years. His notebooks, containing thousands of results without formal proofs, continue to yield new mathematical insights and inspire modern research in areas ranging from string theory to black hole physics. The Ramanujan conjecture influences contemporary work in particle physics and crystallography, while his mathematical formulas have found unexpected applications in computing and cryptography. Perhaps most intriguingly, many of his intuitive leaps remain mysterious, raising profound questions about the nature of mathematical discovery and human cognition. As mathematician Bruce C. Berndt noted, "Paul Erdős spoke of mathematics as a book written by God. Ramanujan was perhaps the only one who read a few pages of that book."
