Back in 1986, Ephraim Fischbach, Sam Aronson, Carrick Talmadge and their collaborators proposed a modification of Newton’s Law of universal gravitation. Underlying this proposal were three tantalizing pieces of evidence: 1) an energy dependence of the CP (particle-antiparticle and reflection symmetry) parameters, 2) differences between the measurements of G, the universal gravitational constant, in laboratories and in mineshafts, and 3) a reanalysis of the Eötvos experiment, which had previously been used to show that the gravitational mass of an object and its inertia mass were equal to approximately one part in a billion. The reanalysis revealed that, contrary to Galileo’s position, the force of gravity was in fact very slightly different for different substances. The resulting Fifth Force hypothesis included this composition dependence and also added a small distance dependence to the inverse-square gravitational force. Over the next four years numerous experiments were performed to test the hypothesis. By 1990 there was overwhelming evidence that the Fifth Force, as initially proposed, did not exist. This book discusses how the Fifth Force hypothesis came to be proposed and how it went on to become a showcase of discovery, pursuit and justification in modern physics, prior to its demise. In this new and significantly expanded edition, the material from the first edition is complemented by two essays, one containing Fischbach’s personal reminiscences of the proposal, and a second on the ongoing history and impact of the Fifth Force hypothesis from 1990 to the present. <.PhysicsGravitationAstronomyObservationsAstronomy—ObservationsPhysical measurementsMeasurementPhilosophy and scienceHistory and Philosophical Foundations of Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P29000Classical and Quantum Gravitation, Relativity Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P19070Astronomy, Observations and Techniqueshttps://scigraph.springernature.com/ontologies/product-market-codes/P22014Measurement Science and Instrumentationhttps://scigraph.springernature.com/ontologies/product-market-codes/P31040Philosophy of Sciencehttps://scigraph.springernature.com/ontologies/product-market-codes/E34000Physics.Gravitation.AstronomyAstronomy—Observations.Physical measurements.Measurement.Philosophy and science.History and Philosophical Foundations of Physics.Classical and Quantum Gravitation, Relativity Theory.Astronomy, Observations and Techniques.Measurement Science and Instrumentation.Philosophy of Science.530Franklin Allanauthttp://id.loc.gov/vocabulary/relators/aut52578Fischbach Ephraimauthttp://id.loc.gov/vocabulary/relators/autBOOK9910254635303321The Rise and Fall of the Fifth Force2533251UNINA03006nam 22008173u 450 991022011080332120250714175954.00-8330-3255-0(CKB)111056486805422(EBL)227795(OCoLC)123109575(SSID)ssj0000238007(PQKBManifestationID)11186972(PQKBTitleCode)TC0000238007(PQKBWorkID)10211109(PQKB)11634238(MiAaPQ)EBC227795(oapen)doab114508(EXLCZ)9911105648680542220130418d2000|||| u|| |engur|n|---|||||txtccrRhetoric versus reality what we know and what we need to know about school vouchers1st ed.Santa Monica RAND Corporation20001 online resource (293 p.)Description based upon print version of record.0-8330-2765-4 PREFACE; SUMMARY; ACKNOWLEDGMENTS; Chapter One FAMILY CHOICE AND THE COMMON SCHOOL; Chapter Two VOUCHERS AND CHARTERS IN POLICY AND PRACTICE; Chapter Three ACADEMIC ACHIEVEMENT; Chapter Four CHOICE; Chapter Five ACCESS; Chapter Six INTEGRATION; Chapter Seven CIVIC SOCIALIZATION; Chapter Eight CONCLUSIONS AND POLICY IMPLICATIONS; REFERENCESThe authors examine the evidence on vouchers in education.
