Short Summary
Srinivasa Ramanujan was an Indian mathematician whose groundbreaking work in number theory and continued fractions has had a profound impact on the field. His intuitive grasp of complex mathematical concepts, despite limited formal training, has earned him a place among history's greatest mathematicians. He is celebrated for his contributions to mathematical analysis, particularly his work on partition functions and the Ramanujan prime. His collaboration with British mathematician G.H. Hardy brought him international recognition and cemented his legacy in mathematics.
Early Life & Education
Born on December 22, 1887, in Erode, India, Srinivasa Ramanujan grew up in a modest Brahmin family. His father worked as a clerk, while his mother was a homemaker and a singer at a local temple. Ramanujan exhibited a prodigious talent for mathematics at a young age, mastering advanced trigonometry by the age of 13. He attended the Government College in Kumbakonam but struggled with non-mathematical subjects, leading to his eventual departure without a degree. Despite these challenges, he continued studying mathematics independently, often borrowing books to further his knowledge.
Career Highlights
Ramanujan's career took a significant turn when he began sending his mathematical findings to established mathematicians. His letters to G.H. Hardy at the University of Cambridge caught Hardy's attention, leading to an invitation to England in 1914. During his time at Cambridge, Ramanujan worked on the partition function and developed the Ramanujan-Hardy number, 1729, known as the "taxicab number." Despite facing cultural and health challenges, he published numerous papers and was elected a Fellow of the Royal Society in 1918. His untimely death in 1920 cut short a promising career.
