Srinivasa Ramanujan
Born 22 December 1887 ยท Tamil Nadu
Died 26 April 1920
Discovered the Ramanujan prime and made groundbreaking contributions to number theory.
๐ Add birthday reminderSrinivasa Ramanujan Iyengar was an Indian mathematician who worked during the early 20th century. Despite having almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems then considered unsolvable.
โจ A detail that surprised us
Ramanujan believed many of his mathematical ideas came from visions of the Hindu goddess Namagiri appearing in his dreams.
1. In 1913, from the small town of Kumbakonam, Ramanujan sent a letter filled with groundbreaking theorems to G.H. Hardy at Cambridge, sparking one of the most unusual academic correspondences in history.
2. ๐ Despite no formal university degree and losing a scholarship in 1904 for neglecting all subjects but math, he published a paper on Bernoulli numbers in 1911 that caught attention in the Indian Mathematical Society.
3. In 1914, Ramanujan traveled to England, becoming the first Indian to be elected a Fellow of Trinity College, Cambridge, where Hardy called some of his results "defeated me completely; I had never seen anything like them before."
4. ๐ Ramanujan compiled nearly 3,900 mathematical results, many completely novel, including the mysterious mock theta functions discovered within his last year and only brought to light decades after his death.
5. In 1919, plagued by hepatic amoebiasis, Ramanujan returned to India, where he died in 1920 at age 32, yet his January 1920 letters still reveal fresh theorems being created during his final days.
6. ๐ His "lost notebook," found in 1976, contained profound number theory ideas that continue to puzzle and inspire mathematicians even a century after his death.
7. โ How did Ramanujanโs self-taught insights from Tamil Nadu, often inspired by dreams of the goddess Namagiri, reshape entire branches of mathematics without conventional training or proof methods?
