Aryabhata, the INDIAN ASTRONOMER AND MATHEMATICIAN also known as Aryabhata the Elder Aryabhata I. He was born in 476, Kusumapura? India and died in the c.550.

Works In Mathematics

• Aryabhatiya covers arithmetic
• Algebra
• Plane trigonometry and
•  spherical trigonometry.
• It also contains continued fractions, quadratic equations, sums-of-power series, and a table of sines.
• Aryabhata worked on the approximation for pi ( {\displaystyle \pi } \pi ), and may have come to the conclusion that {\displaystyle \pi } \pi is irrational.
• Astronomy

Aryabhata's system of astronomy was called the audAyaka system, in which days are reckoned from uday, dawn at lanka or "equator"

Motions of the solar system

Aryabhata correctly insisted that the earth rotates about its axis daily, and that the apparent movement of the stars is a relative motion caused by the rotation of the earth, contrary to the then-prevailing view, that the sky rotated.

Aryabhata described a geocentric model of the solar system, in which the Sun and Moon are each carried by epicycles.

Eclipses

Solar and lunar eclipses were scientifically explained by Aryabhata. He states that the Moon and planets shine by reflected sunlight.

Heliocentrism
As mentioned, Aryabhata advocated an astronomical model in which the Earth turns on its own axis.

India's first satellite named after Aryabhata.
