Available in PDF, EPUB and Kindle. Book excerpt: We predicted gravity values on a tower by upward continuing an extensive set of surface data in order to test the 1/r2 dependence of Newton's Law of Universal Gravitation. We measured gravity at 12 heights up to 454 m on a tower at the Nevada Test Site, and at 91 locations on the surface of the earth within 2.5 kilometers of the tower. These data have been combined with 60,000 surface gravity measurements within 300 kilometers of the tower and have been used to predict the gravitational field on the tower via a solution of Laplace's equation. A discrepancy between the observed gravity values and the prediction could suggest a breakdown of Newtonian Gravity, but we observe none. Our preliminary results are consistent with the Newtonian hypothesis to within 93 +- 95 .mu.gals at the top of the tower, a result which conflicts with the previously reported 500 .mu.gal non-Newtonian signal seen at 562 meters above the earth. 24 refs., 2 figs.

Book Synopsis Selectivity And Discord by : Allan Franklin
Download or read book Selectivity And Discord written by Allan Franklin and published by University of Pittsburgh Press. This book was released on 2002-11-17 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selectivity and Discord addresses the fundamental question of whether there are grounds for belief in experimental results. Specifically, Allan Franklin is concerned with two problems in the use of experimental results in science: selectivity of data or analysis procedures and the resolution of discordant results.By means of detailed case studies of episodes from the history of modern physics, Franklin shows how these problems can be—and are—solved in the normal practice of science and, therefore, that experimental results may be legitimately used as a basis for scientific knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: In No Easy Answers, Allan Franklin offers an accurate picture of science to both a general reader and to scholars in the humanities and social sciences who may not have any background in physics. Through the examination of nontechnical case studies, he illustrates the various roles that experiment plays in science. He uses examples of unquestioned success, such as the discoveries of the electron and of three types of neutrino, as well as studies that were dead ends, wrong turns, or just plain mistakes, such as the "fifth force," a proposed modification of Newton's law of gravity. Franklin argues that science is a reasonable enterprise that provides us with knowledge of the natural world based on valid experimental evidence and reasoned and critical discussion, and he makes clear that it behooves all of us to understand how it works.

Available in PDF, EPUB and Kindle. Book excerpt: In this collection of essays Allan Franklin defends the view that science provides us with knowledge about the world which is based on experimental evidence and on reasoned and critical discussion. In short, he argues that science is a reasonable enterprise. He begins with detailed studies of four episodes from the history of modern physics: (1) the early attempts to detect gravity waves, (2) how the physics community decided that a proposed new elementary particle, 17-keV neutrino, did not exist, (3) a sequence of experiments on K meson decay, and (4) the origins of the Fifth Force hypothesis, a proposed modification of Newton's Law of Universal Gravitation. The case studies are then used to examine issues such as how discord between experimental results is resolved, calibration of an experimental apparatus and its legitimate use in validating an experimental result, and how experimental results provide reasonable grounds for belief in both the truth of physical theories and in the existence of the entities involved in those theories. This book is a challenge to the critics of science, both postmodern and constructivist, to provide convincing alternative explanations of the episodes and issues discussed. It should be of interest to philosophers, historians, and sociologists of science, and to scientists themselves.

Book Synopsis The Search for Non-Newtonian Gravity by : Ephraim Fischbach
Download or read book The Search for Non-Newtonian Gravity written by Ephraim Fischbach and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of the attempts to test the predictions of Newtonian Gravity, describing in detail recent experimental efforts to verify both the inverse-square law and the Equivalence Principle. Interest in these questions has increased in recent years, as it has become recognised that deviations from Newtonian gravity could be a signal for a new fundamental force in nature. This is the first book devoted entirely to this subject, and will thus be useful to both graduate students and researchers interested in this field. It describes the ideas that underlie searches for such deviations, focusing on macroscopic tests. A comprehensive bibliography of some 450 entries supplements the text.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides the reader with a detailed and captivating account of the story where, for the first time, physicists ventured into proposing a new force of nature beyond the four known ones - the electromagnetic, weak and strong forces, and gravitation - based entirely on the reanalysis of existing experimental data. 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.
