42. Jayant Vishnu Narlikar
Jayant Vishnu Narlikar (born July 19, 1938) is an Indian astrophysicist. Narlikar is a proponent of steady state cosmology. He developed with Sir Fred Hoyle the conformal gravity theory, commonly known as Hoyle?Narlikar theory. It synthesizes Albert Einsteins Theory of Relativity and Mach's Principle. It proposes that the inertial mass of a particle is a function of the masses of all other particles, multiplied by a coupling constant, which is a function of cosmic epoch. In cosmologies based on this theory, the gravitational constant G decreases strongly with time.
Narlikar was born in Kolhapur, India on July 19, 1938 in a family of Karhade Brahmin scholars. His father, Vishnu Vasudev Narlikar, was a mathematician who served as a professor and later as the Head of the Department of Mathematics at Banaras Hindu University, Varanasi. Jayant's mother, Sumati Narlikar, was a scholar of Sanskrit language. Jayant studied in Kendriya Vidyalaya Banaras (till class 12) and Banaras Hindu University (12th Onwards) campus, Varanasi.
Narlikar received his Bachelor of Science degree from Banaras Hindu University in 1957. He then began his studies at Fitzwilliam House, Cambridge University in England, where he received a B.A. in mathematics in 1959 and was Senior Wrangler. This appears to have been the first time, and perhaps the only time, that a student was Senior Wrangler who was a non-collegiate member of the University at the time. In 1960, he won the Tyson Medal for astronomy. During his doctoral studies at Cambridge, he won the Smiths Prize in 1962. After receiving his Ph.D. in 1963 under the guidance of Fred Hoyle, he served as a Berry Ramsey Fellow at King's College in Cambridge and earned an M.A. in astronomy and astrophysics in 1964. He continued to work as a Fellow at King's College until 1972. In 1966, Fred Hoyle established the Institute of Theoretical Astronomy in Cambridge, and Narlikar served as the founder staff member of the institute during 1966-72.
In 1972, Narlikar took up Professorship at the Tata Institute of Fundamental Research (TIFR) in Mumbai, India. At the TIFR, he was in charge of the Theoretical Astrophysics Group. In 1988, the Indian University Grants Commission set up the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune, and Narlikar became the Founder-Director of IUCAA. Narlikar is internationally known for his work in cosmology, especially in championing models alternative to the popular Big Bang model. During 1994-1997, he was the President of the Cosmology Commission of the International Astronomical Union. His research work has involved Machs Principle, quantum cosmology, and action-at-a-distance physics. During 1999-2003, Narlikar headed an international team in a pioneering experiment designed to sample air for microorganisms in the atmosphere at heights of up to 41 km. Biological studies of the collected samples led to the findings of live cells and bacteria,[citation needed] which introduced the possibility that the earth is being bombarded by microorganisms, some of which might have seeded life itself on earth.[citation needed][dubious ? discuss] Narlikar was appointed as the Chairperson of The Advisory Group for Textbooks in Science and Mathematics, the textbook development committee responsible for developing textbooks in Science and Mathematics, published by NCERT, which are used widely as standard textbooks in many Indian schools.
43. K R Ramanathan
Kalpathi Ramakrishna Ramanathan (28 February 1893 ? 31 December 1984) was an Indian physicist and meteorologist. He was the first Director of Physical Research Laboratory, Ahmedabad. Ramanathan was awarded Padma Bhushan in 1965 and Padma Vibhushan in 1976.Born in Kalpathi, Palakkad, to a Sanskrit scholar, Ramanathan received a B.A. degree from the Government Victoria College, Palakkad and an M.A. degree in physics from the Presidency College, Madras.

45. Kariamanickam Srinivasa Krishnan
"Padma Bhushan Sir Kariamanickam Srinivasa Krishnan, FRS, (4 December 1898 ? 14 June 1961) was an Indian physicist. He was a co-discoverer of Raman scattering, for which his mentor C. V. Raman was awarded the 1930 Nobel Prize in Physics.Kariamanickam Srinivasa Krishnan, Iyengar generally referred to as K. S. Krishnan or KSK, was born on December 4, 1898 in Watrap, Tamil Nadu. His father was a farmer-scholar deeply versed in Tamil and Sanskrit literature. He had his early schooling in G.S. Hindu Higher Secondary school, Srivilliputhur near to his native village, after which he attended the American College, Madurai and the Christian College, Madras where after gaining his degree in Physics he became a Lecturer in Chemistry.In 1920, Krishnan went to work with C.V. Raman at the Indian Association for the Cultivation of Science, Kolkata (then Calcutta). There he engaged himself in experimental study of the scattering of light in a large number of liquids and its theoretical interpretations. He played a significant role in the discovery of the Raman Effect.
In 1928 he moved to the Dacca University (now in Bangladesh) as the Reader in the physics department where he studied magnetic properties of crystals in relation to their structure. Krishnan, along with other rising scientists such as Santilal (S.) Banerjee, B.C. Guha, and Asutosh Mookerjie developed an elegant and precise experimental technique to measure the magnetic anisotropy of dia - and paramagnetic crystals. Their findings were published by the Royal Society of London in 1933 under the title, Investigations on Magne-Crystallic Action.
In 1933 he returned to Kolkata to take up the post of Mahendralal Sircar Professor of Physics in the Indian Association for the Cultivation of Science where he continued to collaborate fruitfully with Dr. Santilal Banerjee to elaborate on the magnetic properties of crystals in relation to their structure. Their joint papers and communications (published in Nature, Terrestrial Magnetism and Atmospheric Electricity, and by the Royal Society), remain to this day, aside from a number of other pathbreaking contributions they also published in various Physics journals, the most definitive scientific studies on the structure and tendencies of small crystals. Their experiments in Dhaka and continued collaborative research in Kolkata led to what is now known as the Krishnan Banerjee method in measuring the magnetic susceptibility of small crystals.
In 1940 Krishnan was elected as Fellow of the Royal Society. His Royal Society candidature certificate in 1935 read: Distinguished for his investigations in molecular optics and in magne-crystalline action:collaborated with Sir C.V. Raman in extensive theoretical and experimental studies on light scattering, molecular optics and in the discovery of the Raman Effect (1928). More recently has been publishing many valuable investigations (Phil Trans Royal Society and elsewhere) on the significance of magnetic anisotropy in relation to crystal architecture and thermo-magnetic behaviour at the lowest temperatures. Has published important work on pleochroism in crystals and its relation to photo-dissociation. Leader of an active school of research in Calcutta.In 1942, he moved to Allahabad University as Professor and Head of the Department of Physics where he took up the physics of solids, in particular of metals. He was knighted in the 1946 Birthday Honours List and awarded the Padma Bhushan by the Government of India in 1954. He was the first recipient of the prestigious Bhatnagar Award in 1958."
46. Kedareswar Banerjee
Kedareswar Banerjee (September 15, 1900 ? April 30, 1975) was an X-ray crystallographer and director of the Indian Association for the Cultivation of Science, Kolkata. Early in his career he determined the structures of naphthalene and anthracene. In 1931, he worked with Sir William Henry Bragg and developed one of the first direct methods of crystal structure determination. He was Professor of Physics at the Indian Association for the Cultivation of Science from 1943 to 1952 and Director of the Association from 1959 until his retirement in 1965. Between 1952 and 1959 he was Head of the Department of Physics at Allahabad University. His interests in crystallography were widespread and, with his death, India has lost a renowned teacher. K. Banerjee joined the research group of Sir C. V. Raman at the Indian Association for the Cultivation of Science (IACS), Calcutta, a premier Indian research institute of India. He worked in various institutions including IACS, the India Meteorological Department, University of Dhaka and Allahabad University and finally retired as the Director of IACS, Calcutta in 1965. Prof. Banerjee explained some points of crystal research to Homi J. Bhabha (21 Dec. 1956) also .
47. Kotcherlakota Rangadhama Rao
Prof. Kotcherlakota Rangadhama Rao (9 September 1898 ? 20 June 1972) was an Indian physicist in the field of Spectroscopy. Rangadhama Rao is best known for his work on spectroscopy, his role in the development of Nuclear Quadrupole Resonance (NQR), and his long association with the physics laboratories of Andhra University. In his later years, he became known for his position as the Principal of all the colleges of Andhra University before their divisions into separate colleges, viz., AU College of Arts and Commerce, AU College of Engineering, AU College of Law, AU College of Pharmacy and AU College of Science and Technology. Rangadhama Rao was known both for his scientific ability and his interpersonal relations and volatile personality
In 1924, Dr. K. Rangadhama Rao joined Dr. A.L.Narayan as a research scholar in University of Madras. Both of them worked tenaciously to build up a first rate spectroscopic laboratory second to none in the country. They had then with them a constant deviation spectrograph, a small quartz spectrograph and a medium quartz spectrograph. All these were of low dispersion and low resolving power. At this stage of their work, they required an instrument of high dispersion and high resolving power, which they could not afford. So, K.R.Rao went to Calcutta, where a ten-foot concave grating was available in the Indian Association for the Cultivation of Science of which C. V. Raman was Director and with the facilities provided there, they further extended their work on analysis of spectra in the visible and ultraviolet regions. He was guided in his research career by Prof. A.Fowler at the Imperial College of Science and Technology, London in 1930 in Atomic Spectra for two years for which he was awarded the D.Sc. Degree from London University. In 1930, he had the opportunity of working under Prof. F.Paschen at the Physikalische Technische Reichsanstalt in Berlin for six months and under Prof. Manne Seigbahn in Upsala, Sweden on Vacuum Spectroscopy for another six months. His interest in the field of Spectroscopy was so much that he built a Vacuum Spectrograph of his design with his own expenses at Potsdam, Germany. Prof. K.R.Rao's contribution towards physics has placed him in a high position even in his times. His contributions include development of Diatomic and Polyatomic Molecular Spectroscopy laboratory dealing with High Resolution Vibrational structure in electronic transitions, U.V.Absorption, Infrared Absorption, Raman scattering, Fluorescence and Phosphorescence and Crystal Spectra. He also reached the level of construction of microwave test benches and using these techniques he created different lines of investigations in dielectrics. He contributed to the development of Radio Frequency Spectroscopy which branched into Nuclear Quadrupole Resonance (NQR), Nuclear Magnetic Resonance (NMR) and Electron Spin Resonance (ESR) spectroscopy. In India, work on NQR was first initiated by Prof. K. Rangadhama Rao in the Physics laboratories of Andhra University.
Kotcherlakota Rangdhama Rao was the Principal of Andhra University Colleges from 1949-57. He was appointed as Emeritus Professor of Physics at Andhra University (1966?72) and was special officer for the establishment of Sri Venkateswara University, Tirupathi (1954).
