Mathematicians of foreign origin

Pythagoras (Father of Numbers): He introduced the Pythagorean theorem. This theorem reveals the relationship between the sides of a right-angled triangle, influencing mathematics and shaping various scientific disciplines for centuries.

Euclid: Also known as the Father of Geometry, he established five postulates forming the basis of Euclidean Geometry. His book, Elements, is a collection of all the knowledge developed in Greek mathematics spanning over 23 centuries of mathematics.

Archimedes: Archimedes established the foundation for calculus with the method of exhaustion and the measurement of a circle’s circumference and area. Archimedes also gave an accurate approximation to “Pi” and showed that he could approximate square roots accurately. He invented a system for expressing large numbers.

Isaac Newton: Co-inventor of calculus, Newton conceived the Laws of Motion, and the Law of Universal Gravitation, and developed the method of Fluxions, an early form of differentiation for complex calculations – hugely impacting physics and mathematics.

Gottfried Wilhelm Leibniz: Leibniz invented the modern standard notation for differentiation and made significant contributions to many areas of mathematics like algebra, logic, and topology.

Carl Friedrich Gauss: Gauss contributed extensively to number theory, algebra, statistics, and analysis. He is known for the Fundamental Theorem of Algebra and Gauss’s Law in electrostatics.

Ada Lovelace: Known as the world’s first computer programmer, Lovelace devised an algorithm intended to be processed by Charles Babbage’s Analytical Engine, paving the way for modern computing. The example she wrote of one sequence was how to calculate Bernoulli numbers. This is regarded by computer historians as the first computer program.

George Boole: Boole invented Boolean algebra, the basis of all modern computer arithmetic. This binary system of logic is essential in electrical engineering and computer science.

John von Neumann: Notably contributed to the von Neumann architecture, an early model of computation, and the Game Theory, providing a mathematical framework for decision-making processes.

Albert Einstein: Although primarily known as a physicist, Einstein’s Theory of Relativity intertwines physics and mathematics. It includes the famous Mass-Energy equivalence equation (E=mc^2), which revolutionised mathematical physics.

Mathematicians of Indian origin

  1. Aryabhata I (476-550): Regarded as the pioneer of Indian mathematics, Aryabhata I was a renowned mathematician and astronomer. His most famous work laid the foundation of algebra and significantly improved number systems. His advancements in astronomical theories remain influential.
  2. Brahmagupta (598–668): Brahmagupta was a celebrated mathematician and astronomer who expanded Aryabhata’s work. He is particularly credited for establishing critical rules of arithmetic involving zero and negative numbers. His work, Brāhmasphuṭasiddhānta, presented ground-breaking mathematical theories and astronomical deductions.
  3. Bhāskara II (1114–1185): Often known as Bhaskaracharya, Bhāskara II was an esteemed mathematician and astronomer whose work linked ancient and modern mathematics in India. His most famous work, Lilavati, contained comprehensive solutions to mathematics problems involving arithmetic, algebra, and geometry.
  4. One of his most significant works is the “Siddhanta Siromani,” a treatise comprising four parts: Lilāvati (arithmetic), Bijaganit (algebra), Grahaganit (mathematical astronomy), and Golādhyāya (sphere). Bhaskara II is also recognized for his accurate approximations of certain mathematical concepts, including pi and the sine function.

  5. Madhava of Sangamagrama (1350–1425): Founder of the Kerala School of Astronomy and Mathematics, Madhava Sangamagrama introduced infinite series expansions for various trigonometric functions. His works on infinite series, trigonometric functions and geometric series were centuries ahead before similar work was done by European mathematicians.
  6. Madhava’s series of sine, cosine, tangent, and arctangent are significant because they brought in the advent of calculus.

  7. Nilakantha Somayaji (1444-1544): A disciple of the Kerala School of Astronomy and Mathematics, Somayaji authored several acclaimed works including the “Tantrasangraha,” which covered various aspects of astronomy, and “Aryabhatiyabhasya,” a commentary on Aryabhata’s Aryabhatiya.
  8. Apart from his main focus on astronomy, Somayaji also made important contributions to mathematics, developing sophisticated mathematical techniques for astronomical calculations. His works, particularly the ‘Tantrasangraha,’ influenced later astronomers across regions and timelines.

  9. Raj Chandra Bose (1901–1987): Raj Chandra Bose was a renowned Indian mathematician and statistician known for his work in design theory and the theory of error-correcting codes, which had significant implications for communication technology. His research on binary sequences and orthogonal arrays continues to be influential in computer and information science.
  10. Srinivas Ramanujan (1887–1920): Srinivas Ramanujan’s contributions were in mathematical analysis, number theory, and continued fractions.
  11. His first paper published a 17-page work on Bernoulli numbers that appeared in 1911 in the Journal of the Indian Mathematical Society. Although Ramanujan lacked formal education in mathematics, his natural proficiency led him to formulate theories along with G.H. Hardy, a famous mathematician at Cambridge University.

    Hardy and Ramanujan developed a new method, now called the circle method, to derive an asymptotic formula for this function. One significant result of the Hardy-Ramanujan collaboration was a formula for the number p(n) of partitions of a number ‘n’.

  12. Harish-Chandra (1923–1983): Born as Harish Chandra Mehrotra, he simplified the representation theory of semisimple Lie groups and automorphic forms. His work in infinite-dimensional group representations remains impactful in theoretical physics.[8]
  13. Calyampudi Radhakrishna Rao (1920-2023): An eminent statistician, C.R. Rao is renowned for his work in theoretical statistics and mathematics. His contributions, such as the Cramer-Rao inequality and Rao-Blackwell theorem, remain core concepts in statistical theory.
  14. Manjul Bhargava (1974- ): Manjul Bhargava, the first person of Indian origin to win the Fields Medal, is famous for his contributions to number theory. His most significant work includes generalisations of the Gauss composition and his 14 new Gauss-style composition laws.
