Mathematician:Mathematicians/Sorted By Nation/India

For more comprehensive information on the lives and works of mathematicians through the ages, see the MacTutor History of Mathematics archive, created by John J. O'Connor and Edmund F. Robertson.

The army of those who have made at least one definite contribution to mathematics as we know it soon becomes a mob as we look back over history; 6,000 or 8,000 names press forward for some word from us to preserve them from oblivion, and once the bolder leaders have been recognised it becomes largely a matter of arbitrary, illogical legislation to judge who of the clamouring multitude shall be permitted to survive and who be condemned to be forgotten.

-- Eric Temple Bell: Men of Mathematics, 1937, Victor Gollancz, London

Baudhayana $($$\text {c. 800 BCE}$$)$

Indian mathematician, also a priest, believed to have flourished c. $800$ BCE.

Believed to have been a skilled craftsman, thus to have used his mathematical expertise in practical ways.

Did some early research into creating a circle with the same area as a given square.

Discovered $\pi$ to some degree of precision, and discovered what is now known as Pythagoras's Theorem.

Also evaluated the square root of 2 to five decimal places of accuracy.

Pingala $($$\text {c. 5th or 2nd century B.C.E.}$$)$

Indian mathematician about whom practically nothing is known, not even when he lived.

Notable for being the first in history to mention what is now known as Pascal's Triangle.

Indian mathematician and astronomer.

An early believer in the irrationality of $\pi$, and developed an approximation for it of $3.1416$.
