Most of the theories were developed by the great scientists by using sheer power of observations and the genius methods of intellectual calculations. Such observations were possible because I feel the era of 18th and 19th century when most of the scientific theories got established (medival time frame), was less chaotic in terms of the way information is spread in abundance at present.
India produced some great scientist, but India I believed always stayed chaotic with its large population. Creativity is often nurtured only many times in deep silence and meditation. India sadly lacks such environment with its overall societial changes.
Indians I believe are thus less of observant and more of followers and so make a less fortunate scientific contribution overall to the world of science. Because sheer reason of population, which makes many a things impossible to attain.
