General Relativity Extensions and GUT's

19990156021999. Original Manuscript . No Binding. Very Good. Neatly Handwritten Manuscript By An Instructor At Caltech About 120 Pp.With A Transmittal Letter 2 Pp To Prof. Mendel Sachs And His Lengthy E-Mail Reply. 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. <br/> <br/> unknown

The Unity Of Nature Advance Copy November 1979

1980049297Farrar Straus Giroux 1979 1980. 1st Edition 1st Printing. Hardcover. Fine/Fine. X 406 Pp. Blue Cloth Lettered In Silver. First Printing 1980 Stated. Fine In Fine Dust Jacket Priced $20.00. Advance Copy With The Publisher's Transmittal Letter To A Book Salesman Dated Nov. 30 1979. Carl Friedrich Freiherr Von WeizsäckerA 1912 - 2007 Was A German Physicist And Philosopher. A Member Of The Prominent Weizsäcker Family He Was Son Of The Diplomat Ernst Von Weizsäcker Elder Brother Of The Former German President Richard Von Weizsäcker Father Of The Physicist And Environmental Researcher Ernst Ulrich Von Weizsäcker And Father-In-Law Of The Former General Secretary Of The World Council Of Churches Konrad Raiser. Weizsäcker Made Important Theoretical Discoveries Regarding Energy Production In Stars From Nuclear Fusion Processes. He Also Did Influential Theoretical Work On Planetary Formation In The Early Solar System. In 1938 Weizsäcker Developed A Theory On The Formation Of The Solar System Based On Considerations Regarding The Unequal Share Of Lighter And Heavier Elements In The Sun And The Solar System's Terrestrial Planets. His Views Were Later Generally Acknowledged And Refined By A Large Number Of Other Physicists And Astronomers. According To The Theory The Sun And Its Planets Evolved From A Gas Cloud Made Up Of 99% Hydrogen And Helium And 1% Of Heavier Elements. Some 10% Of The Cloud Remained Around The Sun As An Extensive Atmosphere During An Initial Phase And The 1% Of Heavier Elements Within This 10% Of The Total Mass Of The Cloud Would Tally With The Fraction Of Roughly 1% That The Planets Contribute To The Mass Of The Solar System Today. The Theory Also Helped To Explain The Empirically Observed Regular Pattern Of Increase In The Diameters Of The Orbits Of The Planets Of The Solar System From Inward To Outward. This Result Was A Natural Outcome Of The Increasing Size Of "Planetary Eddies" Of Gas And Dust Farther From The Centre Of The Early Solar System. A Further Implication Of His Theory Was That Many Stars Out In The Universe With Characteristics Similar To The Sun Would Have To Be Expected To Possess Planetary Systems Similar To Our Own. Shortly After The End Of The Second World War In Europe The Russian Émigré American Physicist George Gamow Co-Authored An Influential Paper Supporting Weizsäcker's Work On Planetary Formation In The Early Solar System. In His Late Career He Focused More On Philosophical Ethical And Historical Issues And Was Awarded Several International Honours For His Work In Those Areas. During The Second World War Weizsäcker Joined The German Nuclear Weapons Program Participating In Efforts To Construct An Atomic Bomb While Based At The Kaiser Wilhelm Institute In Berlin. As Early As August 1939 Albert Einstein Warned U.S. President Franklin D. Roosevelt About This Research And Highlighted That "The Son Of The German Under-Secretary Of State Von Weizsäcker Is Attached To The Kaiser-Wilhelm-Institut In Berlin Where Some Of The American Work On Uranium Is Now Being Repeated." As A Protégé Of Werner Heisenberg Weizsäcker Was Present At A Crucial Meeting At The Army Ordnance Headquarters In Berlin On 17 September 1939 At Which The German Atomic Weapons Program Was Launched. Early In The War - Possibly Until 1942 - He Hoped A Successful Nuclear Weapons Project Would Earn Him Political Influence. In July 1940 He Was Co-Author Of A Report To The Army On The Possibility Of "Energy Production" From Refined Uranium. The Report Also Predicted The Possibility Of Using Plutonium For The Same Purpose Including The Production Of A New Type Of Explosives. During Summer 1942 Weizsäcker Filed A Patent On A Transportable "Process To Generate Energy And Neutrons By An Explosion. E.G. A Bomb". The Patent Application Was Found In The 1990S In Moscow. <br/> <br/> Farrar Straus Giroux 1979 hardcover
