Download or read book The Constants of Nature written by John Barrow and published by Vintage. This book was released on 2009-05-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reality as we know it is bound by a set of constants—numbers and values that dictate the strengths of forces like gravity, the speed of light, and the masses of elementary particles. In The Constants of Nature, Cambridge Professor and bestselling author John D.Barrow takes us on an exploration of these governing principles. Drawing on physicists such as Einstein and Planck, Barrow illustrates with stunning clarity our dependence on the steadfastness of these principles. But he also suggests that the basic forces may have been radically different during the universe’s infancy, and suggests that they may continue a deeply hidden evolution. Perhaps most tantalizingly, Barrow theorizes about the realities that might one day be found in a universe with different parameters than our own.

This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Conference on Nuclear Masses and their Determination which was held at the Max Planck I nstitute in Mainz from 10 to 12 July 1956 resulted in the formation by the International Union of Pure and Applied Physics of a Commission on Atomic Masses and Related Constants. Under the auspices of this Commission conferences covering these subjects were held in Hamilton, Ontario (12-16 September, 1960), in Vienna (15-19 July 1963) and in Winnipeg (28 August-1 September 1967). After the last of these conferences the Commission felt that the position regarding nuclear masses was reasonably good and that as a consequence the fundamental constants should get more emphasis in future conferences. For this reason they were very pleased to accept an offer from the National Physical Laboratory to accept the main burden of organizing the Fourth International Conference on Atomic Masses and Fundamental Constants. An Organizing Committee was appointed with the members: J. H. Sanders, Chairman B. W. Petley, Secretary A. Horsfield, Treasurer P. Dean A. H. Wapstra. They were assisted by a Program Committee consisting of: A. H. Wapstra, Chairman E. R. Cohen A. Horsfield W. H. Johnson, Jr. J. H. Sanders J. Terrien.

Download or read book Metrology and Physical Constants written by A. Di Giuseppe and published by IOS Press. This book was released on 2013-10-21 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reliability and accuracy of systems of measurement continue to advance. We are about to enter a period of the most stable measurement system we can imagine with the anticipated new definitions of the SI units of measurement; a direct link between fundamental physics and metrology which will eliminate the current definition of the kilogram, until now based upon an artifact. This book presents selected papers from Course 185 of the Enrico Fermi International School of Physics, held in Varenna, Italy, in July 2012 and jointly organized with the Bureau International des Poids et Mesures (BIPM). The papers delivered at the school covered some of the most advanced topics in the discipline of metrology, including nano-technologies; quantum information and quantum devices; biology and medicine; food; surface quality; ionising radiation for health, environment, art and archaeology; and climate. The continuous and striking advances in basic research concerning atomic frequency standards operating both in the visible range and at microwave levels and the applications to satellite systems are also considered, in the framework of a historical review of the international organization of metrology, as are the problems inherent in uncertainty statements and definitions. This book will be of interest to all those whose work involves scientific measurement at the highest levels of accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade of the 20th century, many improvements took place in the field of metrology and fundamental constants. These developments and improvements are discussed in this book. The old caesium SI second definition has found a new realization with the fountain approach, replacing the classical thermal atomic beam. The use of cold atom techniques, slowed down and cooled, has opened a number of unexpected avenues for metrology and fundamental constants, one of these possibilities being the atom interferometry. Another development was the demonstration of the possiblility of performing a direct frequency division in the visible, using short femtosecond pulses. Many other developments are also discussed.
Download or read book A Fortunate Universe written by Geraint F. Lewis and published by Cambridge University Press. This book was released on 2016-10-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last forty years, scientists have uncovered evidence that if the Universe had been forged with even slightly different properties, life as we know it - and life as we can imagine it - would be impossible. Join us on a journey through how we understand the Universe, from its most basic particles and forces, to planets, stars and galaxies, and back through cosmic history to the birth of the cosmos. Conflicting notions about our place in the Universe are defined, defended and critiqued from scientific, philosophical and religious viewpoints. The authors' engaging and witty style addresses what fine-tuning might mean for the future of physics and the search for the ultimate laws of nature. Tackling difficult questions and providing thought-provoking answers, this volumes challenges us to consider our place in the cosmos, regardless of our initial convictions.

This book was released on 2012-12-06 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sixth International Conference on Atomic Masses was held in East Lansing, Michigan, Sept. 18-21, 1979. The conference was initiated, organized, and sponsored by the Commission on Atomic Masses and Fundamental Constants of the International Union of Pure and Applied Physics. The members of the conference committee are listed below: W. Benenson, Chairman Michigan State University R. C. Barber University of-Manitoba E. R. Cohen Rockwell International Institute of Chemical Physics, V. I. Goldanskii Moscow J. C. Hardy Chalk River, Canada W. H. Johnson University of Minnesota E. Kashy Michigan State University Orsay, France R. Klapisch J. A. Nolen, Jr. Michigan State University R. G. H. Robertson Michigan State University E. Roeckl G. S. I. , Darmstadt B. N. Taylor National Bureau of Standards O. Schult IKF, Julich A. H. Wapstra IFO, Amsterdam N. Zeldes Racah Institute, Jerusalem The conference was a little different from the preceding one (in Paris, 1975) in that the fundamental constant aspects were limited to those directly related to atomic masses. The gap is to be filled by the second International Conference on Precision Measurement and Fundamental Constants which is now scheduled for June 1981 in Gaithersburg, Maryland. Only one of the seven sessions in this conference was devoted to fundamental constant determina tions. The conference was very strongly supported by the Department of Energy, the National Science Foundation, and the International Union of Pure and Applied Physics.

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.
Download or read book The Hidden Variables Theory The Initial Values of the Fundamental Constants in Physics written by Israel Fried and published by Lulu.com. This book was released on 2009-08-25 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this revision: The electric charge of a subatomic particle is originated from its Orbital Angular Momentum (OAM). The electron mass is a magnitude that expresses quantitatively the square of its magnetic flux quantum. The proton, the neutron and all baryons consist of three energy levels on which the quarks are orbiting. The third energy level is equivalent to 80.5 Gev; it plays a role at decaying process through the weak force. The quark's OAM is a third or two thirds of the reduced Planck constant. The proton's missing spin is resolved by quarks OAM contribution. The electron is a bound state composition of a negative Pion and an electron Neutrino. The theory predicts a neutral boson of 160Gev (alongside to W+ boson from a 240Gev decaying particle). The 2007 data analysis at CDF (Tevatron) showed this possibility. Apparently this was a valid finding despite the final results.The 240Gev particle can also decay to two W+ and one W- Bosons instead of 160Gev Boson which makes it hard to be detected.
Download or read book A New time New SI units written by Tony Johansson and published by BoD - Books on Demand. This book was released on 2019-11-04 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new time concept is presented. It concerns the SI unit and quantities for the standard. The physics is analyzed on time. This explication set the fundaments for a new time in most science. I offer clear and simple arguments for most interested readers. The reader reaches the fundaments of contemporary technical time. The application of these theories leads to comprehensively think time in a corrected way. Instead of defining the new time precisely for the standard which is for the responsible to do, the basic ideas around time are formulated, explicated to the new conception easy to apply.
