Download or read book Big G written by Ronald Sherrod and published by Independently Published. This book was released on 2021-10-06 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Newtonian constant of gravitation, G (often referred to as "big G"), is one of the most important of the universal fundamental physical constants. However, its value is the least well-determined of all such constants. This is because G is very difficult to measure reliably. Even though the gravitational force is responsible for star and galaxy formation on the massive scale of the universe, the force itself is minuscule on the tiny scale of the laboratory masses which must be used in the measurement. Consequently, its experimental value is prone to a high degree of inaccuracy. Moreover, it is the viewpoint of most physicists that G is not related to the other fundamental physical constants by any theory or understanding that is currently available. Therefore, it is thought that the value of G can only be obtained by measurement, and not from evaluating it in terms of other fundamental constants whose values are known with much greater precision and accuracy. The work presented in the book is an attempt to break through this mental barrier by demonstrating through numerical analysis that G is definitely related to the other fundamental constants. Consequently, it is possible to propose an exact value for G (to nine significant figures) that is obtainable from evaluation instead of from measurement.
Download or read book Measuring Big G the Newtonian Constant with a Frequency Metrology Approach written by Andrea De Marchi and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new approach is described and discussed to the determination of the Newtonian gravitational constant G, which is based on the very powerful measurement of the frequency difference between two similar oscillators. The rate of change of time delay between the two is equal to their relative frequency difference, and small variations of either one can then be detected via delay monitoring with resolution limited only by time resolution and frequency stability of the two oscillators. The latter should be highly sensitive to gravitational field, to measure G, which triggers the choice of simple pendulums as field detectors. Since the relative effect on frequency readily obtainable in the lab by well-controlled variations of the gravitational field is on the order of 10−7, stabilities on the order of 10−12 are needed of the relative frequency difference if measurement of the fifth decimal digit of G is the target of the experiment. It is argued that such high stability is possible with a pendulum properly designed for being locally isochronous and showing an adequately high Q factor. The latter is projected to reach possibly 107 or more with the discussed design.
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.
Download or read book Atom Interferometry written by G.M. Tino and published by IOS Press. This book was released on 2014-10-16 with total page 807 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since atom interferometers were first realized about 20 years ago, atom interferometry has had many applications in basic and applied science, and has been used to measure gravity acceleration, rotations and fundamental physical quantities with unprecedented precision. Future applications range from tests of general relativity to the development of next-generation inertial navigation systems. This book presents the lectures and notes from the Enrico Fermi school "Atom Interferometry", held in Varenna, Italy, in July 2013. The aim of the school was to cover basic experimental and theoretical aspects and to provide an updated review of current activities in the field as well as main achievements, open issues and future prospects. Topics covered include theoretical background and experimental schemes for atom interferometry; ultracold atoms and atom optics; comparison of atom, light, electron and neutron interferometers and their applications; high precision measurements with atom interferometry and their application to tests of fundamental physics, gravitation, inertial measurements and geophysics; measurement of fundamental constants; interferometry with quantum degenerate gases; matter wave interferometry beyond classical limits; large area interferometers; atom interferometry on chips; and interferometry with molecules. The book will be a valuable source of reference for students, newcomers and experts in the field of atom interferometry.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date account of the precise experiments that can be performed in a terrestrial laboratory and are used to explore the nature of universal gravitation. The experiments required are at the limits of sensitivity of mechanical measurements. The problems of experiment design are discussed, and critical accounts given of the principal experiments testing the inverse square law and the principle of equivalence, and measuring the constant of gravitation. An analysis of the effects of noise and other disturbances is also provided, further highlighting the care that is needed in experimental design and performance. The motivation for undertaking such experiments is also discussed.

Download or read book The Gravitational Constant Generalized Gravitational Theories and Experiments written by V. de Sabbata and published by Springer Science & Business Media. This book was released on 2004-03-31 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: An up-to-date description of progress and current problems with the gravitational constant, both in terms of generalized gravitational theories and experiments either in the laboratory, using Casimir force measurements, or in space at solar system distances and in cosmological observations. Contributions cover different aspects of the state and prediction of unified theories of the physical interactions including gravitation as a cardinal link, the role of experimental gravitation and observational cosmology in discriminating between them, the problem of the precise measurement and stability of fundamental physical constants in space and time, and the gravitational constant in particular. Recent advances discussed include unified and scalar-tensor theories, theories in diverse dimensions and their observational windows, gravitational experiments in space, rotational and torsional effects in gravity, basic problems in cosmology, early universe as an arena for testing unified models, and big bang nucleosynthesis.
Download or read book From Newton to Einstein written by F Todd Baker and published by Morgan & Claypool Publishers. This book was released on 2014-12-01 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Newton to Einstein is a book devoted to classical mechanics. "Classical" here includes the theory of special relativity as well because, as argued in the book, it is essentially Newtonian mechanics extended to very high speeds. This information is expanded from the author's popular Q&A website, a site aimed primarily at general readers who are curious about how physics explains the workings of the world. Hence, the answers emphasize concepts over formalism, and the mathematics is kept to a minimum. Students new to physics will find discussion and quantitative calculations for areas often neglected in introductory courses (e.g. air drag and non-inertial frames). The author gives us a more intuitive approach to special relativity than normally taught in introductory courses. One chapter discusses general relativity in a completely non-mathematical way emphasizing the equivalence principle and the generalized principle of relativity; the examples in this chapter can offer a new slant on applications of classical mechanics. Another chapter is devoted to the physics of computer games, sci-fi, superheros, and super weapons for those interested in the intersection of popular culture and science. Professional scientists will find topics that they may find amusing and, in some cases, everyday applications that they had not thought of. Brief tutorials are given for essential concepts (e.g. Newton's laws) and appendices give technical details for the interested reader.
