Indian Mathematicians and Astronomers

Aryabhata, who lived in the 5th century CE, is widely recognized as the 'Father of Indian Mathematics' for his contributions to astronomy, mathematics, and trigonometry, including the concept of zero and the decimal system.

Aryabhata, in his treatise 'Aryabhatiya', introduced the concept of 'zero' and its use in the decimal system, revolutionizing the field of mathematics.

Brahmagupta, in his work 'Brahmasphuta Siddhanta', introduced the 'Fibonacci sequence' and its mathematical properties, which later became known as the 'Fibonacci sequence' in the Western world.

Bhaskara II, in his treatise 'Lilavati', explored the concept of 'infinite series' and developed methods for calculating sums of infinite series, contributing to the early development of calculus.

Brahmagupta, in his work 'Brahmasphuta Siddhanta', developed the 'Pell's equation' and provided a method for solving it, contributing to the field of number theory.

Srinivasa Ramanujan, who lived in the early 20th century, is regarded as one of the greatest Indian mathematicians, known for his remarkable contributions to number theory, mathematical analysis, and his discovery of various mathematical identities and formulas.

Baudhayana, an ancient Indian mathematician, is credited with developing the 'Pythagorean theorem' independently of Pythagoras, as evidenced in the 'Baudhayana Sulba Sutra'.

Aryabhata, in his work 'Aryabhatiya', developed trigonometric functions such as sine, cosine, and versine, contributing to the field of astronomy and trigonometry.

Aryabhata was a major figure in Indian astronomy. He lived in the 5th century CE and is known for his work on the heliocentric model of the solar system. Aryabhata also developed a number of mathematical techniques that are still used today.

Bhaskara II was a major figure in Indian astronomy. He lived in the 12th century CE and is known for his work on the heliocentric model of the solar system. Bhaskara II also developed a number of mathematical techniques that are still used today.

Brahmagupta, an Indian mathematician and astronomer, is credited with the formalization of the concept of zero in the 7th century AD.

Srinivasa Ramanujan was a self-taught Indian mathematician who made significant contributions to number theory, including the Hardy-Ramanujan asymptotic formula.

P.C. Mahalanobis developed the VED classification system, which is used to categorize inventory items based on their criticality.

C.R. Rao developed the ABC classification system, which is another method for categorizing inventory items based on their value and usage.

Varahamihira, an Indian mathematician and astronomer, developed the concept of the 'siddhantas', which were influential in astronomy and religious rituals.
