Man work with Great Scientist "Einstein" to developed the new concept of quantum mechanics "Bose Einstein Statistics to explain the fifth state of matter was nothing but Indian Mathematician and Theoretical Physicist " Satyendra Nath Bose". Class of Particles obey  Bose-Einstein Statistics, Bosons was coined by Paul Dirac honor Bose's great contribution in quantum statistics. Bose was born in Kolkata, he completed his BSc in Appied Mathematics in 1913,at Presidency  College. He pursued M.Sc mixed mathematics in 1915 at Science College, Calcutta University. After next year he started his research on "Theory of Relativity". From 1916-21, he was working as a lecturer in Department of Physics Rajabazer Science College. At that time Einstein wrote Special theory of Relativity in German only. Bose and his colleague Saha got permission from Einstein and translate in English. In 1924, Bose wrote an article deriving Plank's Quantum radiation law withou...

  "Fringes are the evidence of interference" Two American Scientist are the inventors of Speed of light. Albert.A.Michelson and Edward. W.Morley American Physicist and Chemist, both are fascinated by light throughout their life.  Michaelson fabricate one interferometer with the help of some lens. They eagerly wanna know  is "ether" existed everywhere in the universe.  While at Annapolis, he conducted his first experiment on the speed of light , as a part of a class demonstration in 1877. After that experiment, he find out the speed of light in air be 299,864+_51 km/s, estimated the speed of light in vaccum  as 299,940 km/s.  They prove that no ether medium is there in earth. To their innovative work, they got noble prize in 1907. Using Michaelson-Morley interferometer, they measured astronomical object diameter.

Sir, C.V.Raman made his trip to London in 1921, invited by English Physicist J.J.Thomson and Lord Rutherford because of Raman's reputation research in acoustics. His nominal research on the vibrations and sound of string instruments  such as Violin, Veena, Tabla and Mridangam. In his return trip from London to Bombay in ship would change his future.  During his voyage, he was fascinated in deep blue sky. His mind blow with sea,think about Rayleigh prediction about sea. Unable to accepting it. Rayleigh explain colour of sea is reflection of sky. When the ship reached the shore. Short a while, Raman find out colour of sea was scattering of sun light in water molecule, blue was the resulting of the scattering by molecule in air. 💐 Finally He find out the mystery of "Light Scattering'
