I guess no one will take anything away from the achievements of these..Scientist except for in the foot notes..it is interesting Venkat Raman studied in Presidency college in Madras and taught in Calcutta Presidency College. I would be surprised some where their is Bose Connection as he mentions friends..and their is out side possibility my father who studied also in Calcutta Presidency College came across some of them. He used to stay with his aunt that is The famed Jyotirmala..who was also incapable to bear child. I think they used to stay in Calcutta Apartment..of DAL HOUSY SQUARE..it is interesting why he left from their and moved to MEDINI POOR to stay with his cousin..an used to work in a Ration Shop. He fails BA ( geography major ) from Calcutta Board..he then returns to Chittagong and appears for BA exam again and passes....It is from that Ration Job earnings he bought part of a Land in Calcutta with his cousin, the oldest brother of all that reside in Panditiya Residence..just to give hint why He went to Medini Poor who else Dhiman Dr Hounding him..thus one clue is case is in Medinipoor..may be some Ration Shop employees..
In addition ..where this states..of.Tamil Nadu, may not believe it is one of the cause of 40 year war between Tamils and Sinhalese..as Gunomeju was from Sri Lanka.. interesting invokes Optics and some kind of seems like RAY GUN, The way I understand it..it is the simple experiment in PHYSICS lab Taught in my high school..that covers deflection of LIGHTS..it is light source in one end and lenses on clam..as the light passes thru the Lenses..it takes a concentrated form...well it is the same principal this RAY GUN if any..difference is the rays are being passed thru a Metal TUBE with lenses being able to be adjusted..in strange way Light source, lenses all in one track like railway..

Sir Venkata Raman
Biography
Chandrasekhara Venkata Raman was born at Trichinopoly in Southern India on November 7th, 1888. His father was a lecturer in mathematics and physics so that from the first he was immersed in an academic atmosphere. He entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he gained his M.A. degree, obtaining the highest distinctions.His earliest researches in optics and acoustics - the two fields of investigation to which he has dedicated his entire career - were carried out while he was a student.
Since at that time a scientific career did not appear to present the best possibilities, Raman joined the Indian Finance Department in 1907; though the duties of his office took most of his time, Raman found opportunities for carrying on experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta (of which he became Honorary Secretary in 1919).
In 1917 he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. After 15 years at Calcutta he became Professor at the Indian Institute of Science at Bangalore (1933-1948), and since 1948 he is Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he is the Editor. Raman sponsored the establishment of the Indian Academy of Sciences and has served as President since its inception. He also initiated the Proceedings of that academy, in which much of his work has been published, and is President of the Current Science Association, Bangalore, which publishes Current Science (India).
Some of Raman's early memoirs appeared as Bulletins of the Indian Associationfor the Cultivation of Science (Bull. 6 and 11, dealing with the "Maintenance of Vibrations"; Bull. 15, 1918, dealing with the theory of the musical instruments of the violin family). He contributed an article on the theory of musical instruments to the 8th Volume of the Handbuch der Physik, 1928. In 1922 he published his work on the "Molecular Diffraction of Light", the first of a series of investigations with his collaborators which ultimately led to his discovery, on the 28th of February, 1928, of the radiation effect which bears his name ("A new radiation", Indian J. Phys., 2 (1928) 387), and which gained him the 1930 Nobel Prize in Physics.
Other investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942), and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. In 1948 Raman, through studying the spectroscopic behaviour of crystals, approached in a new manner fundamental problems of crystal dynamics. His laboratory has been dealing with the structure and properties of diamond, the structure and optical behaviour of numerous iridescent substances (labradorite, pearly felspar, agate, opal, and pearls).
Among his other interests have been the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision.
Raman has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected a Fellow of the Royal Society early in his career (1924), and was knighted in 1929.

C.V. Raman
The Nobel Prize for Medicine
Dr. Khorana was born in Raipur, Punjab (now in Pakistan). He went abroad to get his doctorate in Chemistry and later settled there. It was his study of the human genetic code and the role it plays in protein synthesis that got him the Nobel Prize.

SUBRAMANIAN CHANDRASHEKAR (1983) 
The Nobel Prize for Physics
Dr S. Chandrashekar, is an Indian-born astrophysicist (a branch of astronomy or the study of space). After studying at the Presidency College in Madras, Dr. Chandrashekhar went to the United States for work and settled there. He has written many books on his field Astrophysics and
Stellar Dynamics. He developed a theory on white dwarf stars forecasts the limit of mass that dwarf stars can have. This limit is known as the Chandrashekar Limit. His theory also explains the final stages of the evolution of stars.
Initially, the IACS was able only to give free public lectures. Nevertheless, these were well-attended by the public. Scientists like J.C Bose & Fr. Lafont gave lectures. But M.L. Sircar was disappointed that young people did not come forward to do real research.
In 1907, a 19-year old officer in the Accountant General's department walked into the IACS premises, wanting to do some research in physics. A.L. Sircar, who was then the head there, enthusiastically accepted him. This was CV Raman, who went on to win the Nobel Prize in 1930.
Though Raman was appointed a professor in 1917 in the University of Calcutta, he preferred to do his research in IACS. And it was there; in 1928 that he discovered the famous Raman Effect.
In the beginning, CV Raman had no good instruments. He used sunlight as a source of light, and his own eyes as a detector. Yet he got his results published in Nature, the world's most prestigious scientific journal. Impressed, the industrialist GD Birla bought him a spectrograph.
CHANDRASHEKAR VENKATA RAMAN (1930)
Nobel Prize for Physics
Born at Thiruvanaikkaval in Tamil Nadu, Raman studied at Presidency College, Madras. Later, he served as Professor of Physics at Calcutta University. C.V. Raman won the Nobel Prize for an important research in the field of optics (light). Raman had found that diffused light contained rays of other wavelengths-what is now popularly known as Raman Effect. His theory explains why the frequency of light passing through a transparent medium changes.
