Displays of empty pride Aryabhata referred to a spherical earth drawing things to it on all sides. But there were many steps to be taken between the observations of the Indian astronomers to the work of the English physicist. He did not use the principle to predict orbits of planets." Bhaskaracharya II, who lived in the 12th century, also mentioned something like gravity. He did not make a universal principle of it. "But he did not say that it was an inverse square law. "Brahmagupta postulated correctly that there is an attraction towards the centre of the earth," said Roddam Narasimha, professor of engineering mechanics at the Jawaharlal Nehru Centre for Advanced Scientific Research. Brahmagupta, a 7th century astronomer, was another. Aryabhata might have been one such giant. Scientific discoveries are not made in a day and even Newton accepted that he saw further “by standing on the shoulders of giants”. “Aryabhata did us credit but we can’t claim that he discovered gravity,” Rao added. Rao has been studying texts of ancient Indian astronomers for 20 years. “In his treatise Aryabhatiya, he says that all particles cling to the surface of the earth but he does not mention an attractive force,” said S Balachandra Rao, director of the Gandhi Center for Science and Human Values in Bengaluru. But it is doubtful whether Aryabhata postulated gravity as the universal, quantifiable force between two objects that we now know it to be. This hypothesis was rejected by later Indian and western astronomers until the emergence of modern heliocentric theory. He postulated that the apparent daily rotation of the sky was actually due to the rotation of the earth. Aryabhata was indeed a remarkable astronomer with many ideas that formed the basis of our modern understanding of the universe. Speaking at the ‘International Conference to Re-establish Vedic India’ held in Delhi over the past weekend, former Indian Space Research Organisation chairman Madhavan Nair declared that 5th century scholar Aryabhata knew about gravitational force before Isaac Newton discovered it more than a millennium later.
