It draws from the whole cultural and technological history of India, during which architecture , astronomy , cartography , metallurgy , logic , mathematics , metrology and mineralogy were among the branches of study pursued by its scholars. For the purposes of this list, inventions are regarded as technological firsts developed in India, and as such does not include foreign technologies which India acquired through contact.

Historians and sociologists have remarked the occurrence, in science , of " multiple independent discovery ". Robert K. Merton defined such "multiples" as instances in which similar discoveries are made by scientists working independently of each other. Commonly cited examples of multiple independent discovery are the 17th-century independent formulation of calculus by Isaac Newton , Gottfried Wilhelm Leibniz and others, described by A. Rupert Hall; [3] the 18th-century discovery of oxygen by Carl Wilhelm Scheele , Joseph Priestley , Antoine Lavoisier and others; and the theory of the evolution of species , independently advanced in the 19th century by Charles Darwin and Alfred Russel Wallace.

He was the first to investigate the harmonic nature of the sound of the Indian drums such as the tabla and the mridangam. He discovered that, when light traverses a transparent material, some of the deflected light changes in wavelength. This phenomenon is now called the Raman scattering and is the result of the Raman effect. In October , he collapsed in his laboratory. He was moved to a hospital and the doctors gave him four hours to live.

Scientists are persons of great minds, who ask question about the phenomenon and systematically answer the question themselves. No doubt, they are curious, creative and well organised. They have the ability to observe new things in a different way. Their discoveries have change the world and gave it a new dimension. It is correctly said by George C.
