India is one of the leading nations in the world in terms of science and technology. India has the second largest pool of scientists and engineers in the world. In terms of technological advancements and scientific achievements India is second to none. India belongs to the select group of countries who have developed indigenous nuclear technology. India is among the few countries which have developed ballistic missiles. In the field of space science India is among the few countries which have the capability to launch GSLV satellite. India's achievements in the field of IT and software are acknowledged all over the world. Here are some interesting facts about science and technology in India.

First Indian Scientist to Win Nobel Prize

Sir Chandrasekhara Venkata Raman (C.V. Raman) was the first Indian scientist to win Nobel Prize. C.V. Raman was awarded the 1930 Nobel Prize in Physics for his work on the scattering of light and for the discovery of the Raman effect, which is named after him. Raman effect relates to the inelastic scattering of a photon. When light is scattered from an atom or molecule, most photons are elastically scattered (Rayleigh scattering). The scattered photons have the same energy (frequency) and, therefore, wavelength, as the incident photons. However, a small fraction of scattered light (approximately 1 in 10 million photons) is scattered from excitations with optical frequencies different from, and usually lower than, the frequency of the incident photons. Raman effect is helpful in analyzing the composition of liquids, gases, and solids.

First Nuclear Power Plant in India

Tarapur Atomic Power Station (T.AP.S.) was the first nuclear power plant in India. The construction of the plant was started in 1962 and the plant went operational in 1969. The 320 MW Tarapur nuclear power station housed two 160 MW boiling water reactors (BWRs), the first in Asia. The Tarapur Plant was originally constructed by the American companies Bechtel...
