The present is an humble attempt to put before the English-knowing public the contibutions of the Jainas in the domain of cosmology and atomic physics. It is not an attempt to seek in ancient texts the substance of modern theories, as some are likely to think, nor is there any attempt to bring by forced, distant and misleading analogies the ancient
