Indian Mathematicians and Astronomers

Varahamihira developed the concept of the zodiac and the twelve signs, which are widely used in astrology and astronomy.

Bhaskara II conducted extensive studies in spherical astronomy and developed trigonometric functions, which are essential in various fields of mathematics and astronomy.

Varahamihira proposed the idea of a geocentric model of the solar system, where the Earth is at the center and the planets revolve around it.

Aryabhata conducted studies on the precession of the equinoxes and calculated the Earth's circumference, which was a remarkable achievement in ancient astronomy.

Varahamihira developed the concept of the nine planets (navagrahas) and their influence on human life, which is a significant aspect of Indian astrology.

Varahamihira wrote the astronomical treatise 'Panchasiddhantika', which is a compilation of five astronomical texts from different schools of thought.
