![]() ![]() ![]() Checkmate for flat earthers and Westerners. It is pertinent to note that Earth was shown spherical back then when no telescopes existed. Varaha slew the demon and retrieved the Earth from the ocean, lifting it on his tusks, and restored Bhudevi to her place in the universe. When the demon Hiranyaksha stole the earth and hid her in the primordial waters, Vishnu appeared as Varaha to rescue her. Welding Sudarshana chakra and Kaumodaki gada, the avatar of Vishnu is associated with the legend of lifting the Earth (Bhudevi) out of the cosmic ocean. ![]() In his third avatar called Varaha, Lord Vishnu is depicted as a boar. Indians and their ancient texts also point out what the Westerners took centuries to unfold and that is the Earth is spherical. Neelakanta in the same book proposed models that became the ‘Tychonic model’ of planetary motion (published by Tycho Brahe in 1583), centuries later. The same expansions of sine, cosine and arctan functions became the Taylor series of today. Series expansion for trigonometric functions was described by Neelakanta in Sanskrit verses in an astronomical treatise called Tantrasangraha. The text Yukti Bhasha, written by the Indian astronomer Jyesthadeva of this school, was a veritable textbook of original calculus and offers detailed explanations of most of the results used today. Those included Bhaskaracharya, Brahmagupta, Varahamihira, and so on. Mathematicians who belonged to Kerala School (1300-1600 CE), a well-known centre of mathematics and astronomy in the 15th and 16th centuries, developed comprehensive theories about the development of Infinitesimal series and its applications which were central to calculus and codified the science in palm leaf bundles (granthas) equivalent to (but far superior yet) modern-day books.

Aryabhata (476–550 CE) and Brahmagupta calculated instantaneous speed (or rate of change) of certain orbital parameters rather than just an average speed (integral calculus) and called this instantaneous motion tat-Kalika (Sanskrit for instantaneous velocity). ![]()
