India was the first country outside the Western world to take to modern science. Within India the lead came from Bengal. JC Bose and PC Ray are the non-West’s first modern scientists. MN Saha’s and SN Bose’s theoretical contributions are fundamental and at the Nobel-prize level. The first Nobel science prize to go outside the West went to the physicist CV Raman for his work in Calcutta. Normally, an activity begins modestly, reaches a peak, declines somewhat and settles on a plateau. Indian science started at the top and had no place to go except downwards. India had an early start but it frittered away the advantage. It would be instructive to find out what happened.]]>

Astronomy, as a study of cosmic environment, was part of scriptures and mythology. Even when Indian astronomy developed as an intellectual discipline in its own right, it consciously sought to maintain links with the sacred literature. Mythology in turn modified itself to take note of scientific advancement. Ketu figures in literature from Rigvedic times, and Rahu from the time of Atharvaveda. Their meaning however has not remained static. Before 499 CE, Rahu is a demon while Ketu denotes phenomena like comets and meteors. There is no connection between the two. After 499 CE, Rahu and Ketu become part of the navagraha, while in addition Ketu continues to be used in the old sense also. ]]>
