He developed the use of galena crystals for making receivers, both for short wavelength radio waves and for white and ultraviolet light. In 1895, two years before Marconi’s demonstration, Bose demonstrated wireless communication using radio waves, using them to ring a bell remotely and to explode some gunpowder. He invented many of the microwave components such as waveguides, horn antennas, polarizers, dielectric lenses and prisms, and even semiconductor detectors of electromagnetic radiation in the last decade of the nineteenth century. He also proposed the existence of electromagnetic radiation from the Sun, which was confirmed in 1944. After that Bose focused his attention to response phenomena in plants. He presented that not only animal but vegetable tissues, produce similar electric response under different kinds of stimuli – mechanical, thermal, electrical and chemical.

Meghnad Saha: Meghnad Saha belonged to District of Dacca, now in Bangladesh. In 1920, Meghnad Saha had developed himself as renowned physicists of the time. Meghnad Saha has contributed in the arena of the thermal ionisation of elements, and it led him to formulate what is known as the Saha Equation. This equation is one of the basic tools for interpretation of the spectra of stars in astrophysics. His theory of high-temperature ionization of elements and its application to stellar atmospheres, as expressed by the Saha equation, is fundamental to modern astrophysics; subsequent development of his ideas has led to increased knowledge of the pressure and temperature distributions of stellar atmospheres.

By studying the spectra of various stars, one can find their temperature and from that, using Saha’s equation, determine the ionisation state of the various elements making up the star. He also invented an instrument to measure the weight and pressure of solar rays. He was also the chief architect of river planning in India. He prepared the original plan for the Damodar Valley Project. He had a great role in the development of scientific institutions throughout India as well as in national economic planning involving technology.

Dr. A. Sivathanu Pillai: Sivathanu Pillai is an eminent Indian scientist. He supervised the conception of indigenously developed missile systems. India's self-sustaining missile developing programme is called BrahMOS. Dr. Pillai developed the concept of the joint venture BrahMOS, which makes India one of the few countries to develop its own ballistic missiles as well as produce and supply missiles in other key areas of the world. The start of BrahMOS led to the negation of the absolute power held by Western countries.

It is documented in research reports that contemporary India has had a strong focus on science and technology, realising that it is a major element of economic development. India is among the uppermost countries in the world in the field of scientific research, positioned as one of the top five nations in the field of space exploration. The country has frequently undertaken space missions, including missions to the moon and the famed Polar Satellite Launch Vehicle (PSLV). On 16 October 2014, Indian Space Research Organisation (ISRO)’s PSLV-C26 successfully launched IRNSS-1C, the third satellite in the Indian Regional Navigation Satellite System (IRNSS), from Satish Dhawan Space Centre, Sriharikota. This is PSLV’s 27th consecutive successful mission. At present, the country has a total of 17 Indian Institutes of Technology (IITs), 31 National Institutes of Technology (NITs), 677# universities awarding about 29,000 doctorate degrees, and about 40 research laboratories run by the Council of Scientific and Industrial Research (CSIR).

Current developments in the field of science and technology in India are as follows:

Indian Space Research Organisation (ISRO) is taking steps towards developing its own reusable rocket using a Winged Reusable Launch Vehicle Technology Demonstrator (RLV-TD), whose tech demo is expected to be conducted in February 2016.

Indian Space Research Organisation (ISRO) has launched six satellites of Singapore aboard the Polar Satellite Launch Vehicle (PSLV-C29) from Satish Dhawan Space Centre in Sriharikota, marking the completion 50 launches from Sriharikota since 1979.

The National Institution for Transforming India Aayog (NITI Aayog) plans to release a blueprint for various technological interventions which need to be incorporated by the Indian manufacturing economy.

The Indian Institute of Science (IISc), Bangalore has become the first Indian institution to enter the Top 100 universities ranking in engineering and technology.

To summarize, Indian scientists have contributed astonishingly in the growth of India. They have augmented the status of India with their scientific achievements and many of the Indian scientists have also received some prestigious international awards as well. The discoveries of the Indian scientists have been appreciated all over the world. After independence, India has accomplished several great scientific achievements. Indian scientists have showed their courage at global level and have made India one of the scientific centres of the world. There are many names like Bhabha, A. Sivathanu Pillai, Narinder Singh Kapany, and many more who made prime position in scientific field.
