  Historians of science are generally unaware of the contributions of India to
physics. The main reason for this is that very little research has been done on
the subject in the recent past, a consequence of the fact that there are few
history of science departments in Indian universities. The objective of this
paper is to present a preliminary outline of early history of physics in India.
The schools of Vaisheshika and Samkhya, that were interested in general
principles of atomic theory and cosmology, are discussed. In particular, ideas
on atoms and molecules, the nature of sound, causality, universals, cosmology,
uniform and non-uniform motions are described.
