Chandrasekhara Venkata Raman Frs 1888 -1970 Was An Indian Physicist Known For His Work In The Field Of Light Scattering. Using A Spectrograph That He Developed He And His Student K. S. Krishnan Discovered That When Light Traverses A Transparent Material The Deflected Light Changes Its Wavelength And Frequency. This Phenomenon A Hitherto Unknown Type Of Scattering Of Light Which They Called "Modified Scattering" Was Subsequently Termed The Raman Effect Or Raman Scattering. In Addition To Being A New Phenomenon Itself The Raman Effect Was One Of The Earliest Proofs Of The Quantum Nature Of Light. Robert W. Wood At The Johns Hopkins University Was The First American To Confirm The Raman Effect In The Early 1929. He Made A Series Of Experimental Verification After Which He Commented Saying "It Appears To Me That This Very Beautiful Discovery Which Resulted From Raman's Long And Patient Study Of The Phenomenon Of Light Scattering Is One Of The Most Convincing Proofs Of The Quantum Theory". The Field Of Raman Spectroscopy Came To Be Based On This Phenomenon And Ernest Rutherford President Of The Royal Society Referred To It In His Presentation Of The Hughes Medal To Raman In 1930 As "Among The Best Three Or Four Discoveries In Experimental Physics In The Last Decade".Raman Received The 1930 Nobel Prize In Physics For The Discovery And Was The First Asian To Receive A Nobel Prize In Any Branch Of Science. With Suri Bhagavantam He Determined The Spin Of Photons In 1932 Which Further Confirmed The Quantum Nature Of Light. With Another Student Nagendra Nath He Provided The Correct Theoretical Explanation For The Acousto-Optic Effect Light Scattering By Sound Waves In A Series Of Articles Resulting In The Celebrated Raman-Nath Theory. Modulators And Switching Systems Based On This Effect Have Enabled Optical Communication Components Based On Laser Systems. Other Investigations He Carried Out Included Experimental And Theoretical Studies On The Diffraction Of Light By Acoustic Waves Of Ultrasonic And Hypersonic Frequencies And Those On The Effects Produced By X-Rays On Infrared Vibrations In Crystals Exposed To Ordinary Light Which Were Published Between 1935 And 1942. In 1948 Through Studying The Spectroscopic Behaviour Of Crystals He Approached The Fundamental Problems Of Crystal Dynamics In A New Manner.104105 He Dealt With The Structure And Properties Of Diamond From 1944 To 1968 The Structure And Optical Behaviour Of Numerous Iridescent Substances Including Labradorite Pearly Feldspar Agate Quartz Opal And Pearl In The Early 1950S. Among His Other Interests Were The Optics Of Colloids And Electrical And Magnetic Anisotropy His Last Interests In The 1960S Were On Biological Properties Such As The Colours Of Flowers And The Physiology Of Human Vision.Raman Was The Paternal Uncle Of Subrahmanyan Chandrasekhar Recipient Of The 1983 Nobel Prize In Physics.

1914ref. 036009Cambridge: Cambridge University Press 1914. 1st Edition 1st Printing. Hardcover. Near Fine/No Jacket. Viii 144 Pp Catalog At End Dated 5/14. Green Cloth Gilt. A Very Near Fine Example Cloth Clean And Entirely Unfaded Gilt Brilliant No Wear To Pages Some Browning To Endpapers Ownership Signature Of An Engineer/Physicist On Front Pastedown. Hughes Went Cavendish Laboratory At Cambridge Where He Studied Under J.J. Thomson Who Had Won The Nobel Prize In Physics In 1906. It Was At Cambridge That Hughes Carried Out What Some Consider His Finest Scientific Work Proving The Validity Of Einstein's Theory Of The Photoelectric Effect. In 1912 He Accepted A Teaching Position At The Newly-Founded Rice Institute In Texas. When World War I Broke Out Hughes Returned To England To Work On Anti-Submarine Devices. Shortly After The War He Left Rice To Take A Research Professorship At Queen's College In Ontario From Which He Was Called To St. Louis By Compton In 1923. For 15 Months In World War Ii Hughes Served As Assistant Director Of The Los Alamos Atomic Energy Project Acting As Recruiting Officer. In An Interview "I Never Saw Such A Collection Of Top Notch Scientists In My Life" He Said "And As You Probably Know Our Whole Chemistry Department Was Brought Lock Stock And Barrel From Los Alamos. I Think Six Of Those Men Are Still Here." "The Big Job Was To Persuade Scientists To Come To Los Alamos Without Telling Them What Was Going On. When I Arrived There Were 250 People In All Scientists And Technicians. When I Left 15 Months Later There Were About 3000." I Asked Hughes About Changes He Has Seen In Physics. "When I Came Here" He Said "We Were Rather Pedestrian In Our Attitude Toward Physics. I Suppose That Attitude Was Rather World-Wide Back Then. We Took Summer Vacations Because There Was No Paid Work To Be Done Then. Now No One Takes Long Vacations. Before World War Ii Physicists Were Hardly Known In Industry. Any Job Was Likely To Be In Teaching Or In Government Re Search. Nowadays Physicists Have Become Acceptable People." His Photoelectric Phenomena Published In 1933 With Dubridge Remained The Standard Work On The Subject Until 1959 When It Went Out Of Print. Cambridge University Press hardcover

Ideas of the Theory of Relativity: General Implications from Physics to Problems of Society

1974ref. 036014Jerusalem: I.P.S.T. / Israel Universities Press / John Wiley & Sons / Halsted Press 1974. 1st Edition 1st Printing. Hardcover. Very Good /No Jacket. Xv 190 Pp. Red Cloth Printed In Black And Pink. First Printing. Inscribed By The Author To The Dedicatee Prof. Abraham Kaplan. Light Wear Rubbing And Bumping At Corners No Fraying Some Fading To Cloth On Spine Panel But Lettering Still Strong. Mendel Sachs 1927 -2012 Was An American Theoretical Physicist. His Scientific Work Includes The Proposal Of A Unified Field Theory That Brings Together The Weak Force Strong Force Electromagnetism And Gravity. Sachs Earned His Bachelors At The University Of California Los Angeles He Then Moved To Columbia University New York For Postgraduate Study. While At Columbia Sachs Was Taught By Willis Lamb And Hideki Yukawa.5 Yukawa Had Agreed To Be Sach's Thesis Advisor But Sachs Decided To Complete His Doctorate Back At Ucla. Following The Award Of His Phd In 1954 Sachs First Post-Doctoral Position Was At The New University Of California Radiation Laboratory At Both Berkeley And Livermore Which Was Run By Edward Teller And Ernest Lawrence And Was Also Home To Bryce Dewitt Who Sachs Would Later Co-Author Articles With In Physics Today. In 1956 Sachs Became A Senior Scientist At Lockheed Missiles And Space Laboratory While At Lockheed Sachs Began Developing With Solomon Schwebel A Field Theory Of Quantum Electrodynamics That Included Broken Symmetries That Did Not Require Recourse To Renormalization Or Perturbation Techniques - The "Schwebel-Sachs" Model. In 1961 He Became A Research Professor At Mcgill University; This Was Followed By A Post As Associate Professor Of Physics At Boston University 1962-1966. In 1964 While At Boston University Sachs Received An Invitation From Paul Dirac To Visit Cambridge University. Sachs Stayed In England For Three Months Where His Wife Yetty Had Family. Sachs Worked With Paul Dirac At The Department Of Applied Mathematics And Theoretical Physics Cambridge University. While Working With Dirac Sachs Also Had The Opportunity To Discuss Ideas With John G. Taylor John Polkinghorne And Graduate Students At Damtp. In 1965 Sachs Had Had A Breakthrough While At The Aspen Physics Institute Colorado. Sachs Was Able To Derive A Result For A Unified Field Theory If Quantum Mechanics Was Considered To Be A Linear Approximation For A Field Theory Of Inertia Expressed In General Relativity. Sachs Argued That The Work Of Albert Einstein And Erwin Schrödinger In General Relativity Did Not Yet Take Account Of The Inertia Of Matter Which Required Consideration Of The Mach Principle. In The Summer Of 1966 Abdus Salam Invited Sachs To Spend A Few Months At The International Centre For Theoretical Physics In Trieste Italy. During This Time Sachs Published The Details Of His Formal Structure Of Quantum Mechanics From A Generally Covariant Field Theory Of Inertia In The Italian Journal Il Nuovo Cimento. In The Autumn Of 1966 He Was Appointed Professor Of Physics At State University Of New York At Buffalo. I.P.S.T. / Israel Universities Press / John Wiley & Sons / Halsted Press hardcover
