Biography of Famous Scientist Srinivasa Ramanujan
Srinivasa Ramanujan: The Self-Taught Mathematical Genius
Early Life and Education:
Srinivasa Ramanujan was born on December 22, 1887, in Erode, Tamil Nadu, India. From an early age, he displayed an extraordinary aptitude for mathematics, and his talent was evident even before formal education. By the age of 12, he had mastered trigonometry and developed his theorems independently.
In 1903, Ramanujan graduated from the Town Higher Secondary School in Kumbakonam, and he enrolled at the Government Arts College in Kumbakonam. However, financial difficulties and his obsession with mathematics led to a neglect of his formal studies.
Mathematical Contributions:
Ramanujan’s mathematical insights were largely self-developed, as he had minimal formal training. He independently discovered many theorems and mathematical concepts, recording his findings in notebooks. His work primarily focused on number theory, infinite series, and modular forms.
In 1910, Ramanujan began corresponding with G. H. Hardy, a distinguished mathematician at the University of Cambridge. Hardy recognized Ramanujan’s unparalleled talent and invited him to England in 1914.
Life in England:
Ramanujan faced challenges in adapting to the British academic environment, both culturally and socially. Despite these difficulties, he collaborated with Hardy and others, producing groundbreaking mathematical results. He became a Fellow of the Royal Society in 1918.
During his time in England, Ramanujan made significant contributions to areas like mock theta functions, elliptic functions, and partition theory. His work on modular forms and mock theta functions had a profound impact on mathematics.
Return to India and Later Life:
Ramanujan returned to India in 1919 due to health issues, but his health continued to decline. He was elected as the first Indian Fellow of the Trinity College, Cambridge, in 1919. Tragically, Srinivasa Ramanujan passed away on April 26, 1920, at the age of 32, leaving behind a legacy of mathematical brilliance.
Legacy:
Srinivasa Ramanujan’s contributions to mathematics have had a lasting impact. His work laid the foundation for many areas of modern mathematics, including number theory, mathematical analysis, and algebraic geometry.
The “Ramanujan-Hardy Number” (1729) is famous for its connection to an anecdote involving a taxi ride shared by Ramanujan and Hardy. This number is often referred to as the “Hardy-Ramanujan Number” and is known as the “Ramanujan-Hardy Taxi Cab Number.”
The Ramanujan-Hardy collaboration resulted in numerous papers and publications, solidifying Ramanujan’s reputation as one of the greatest mathematicians of all time. The impact of his work continues to be felt, and his life story remains an inspiration for aspiring mathematicians worldwide.
