The article discusses the discovery of a previously unknown mathematical theory developed by Srinivasa Ramanujan, an Indian mathematician who lived in the early 20th century. The theory, found in Ramanujan's manuscripts, provides a link between several milestones in the history of mathematics, including Fermat's last theorem and elliptic curves. Ramanujan's work on the theory was several decades ahead of its time and has yielded results that are still interesting to mathematicians today. The discovery was made by two mathematicians from Emory University, who found that Ramanujan's theory also has connections to physics, particularly string theory.
