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.

Available in PDF, EPUB and Kindle. Book excerpt: Time changes most things, and physical constants are seem ingly not immune from this contingency. The publishers' suggestion for a new edition has provided an opportunity for a thorough scrutiny of the contents of this book and for the adjustment to some fourteen years of changes since the last edition. At the same time the contents have been increased by the addition of one or two new tables, and current moves towards the adoption of an international system of units ex plain the appearance in the book, wherever it is practicable, of S. 1. units. However, the habits of a lifetime are not easily changed, and it is too much to expect that despite careful proofreading the change of units has been carried through without errors. I shall be grateful for intimation of such mis takes. I wish moreover to thank all those who in the past have taken the trouble to draw my attention to errors, or to superior determinations, or simply to offer advice or criticism. For those who do not find what they seek in this collection, more complete compilations of physical constants are to be found in: Tables of Physical and Chemical Constants, G. W. C. Kaye and T. H.

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.

This book was released on 2013-12-01 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this NATO Advanced Study Institute was to pre sent a tutorial 'introduction both to the basic physics of recent spectacular advances achieved in the field of metrology and to the determination of fundamental physical constants. When humans began to qualify their description of natural phenomena, metrology, the science of measurement, developed along side geometry and mathematics. However, flam antiquity to modern times, the role of metrology was mostly restricted to the need of commercial, social or scientific transactions of local or at most national scope. Beginning with the Renaissance, and particularly in western Europe during the last century, metrology rapidly developed an international character as a result of growing needs for more accurate measurements and common standards in the emerging indus trial society. Although the concerns of metrology are deeply rooted to fundamental sciences, it was, until recently, perceived by much of the scientific community as mostly custodial in character.

This book was released on 2013-10-22 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mechanical and Physical Properties of the British Standard En Steels (B.S. 970 - 1955), Volume 2 focuses on the most commonly used range of steels in the United Kingdom - B.S.970 En Steels. The publication first offers information on 3 percent nickel steel and 3 1⁄2 percent nickel steel. Concerns focus on welding, machinability, hot working and heat treatment temperatures, physical properties, transformation characteristics, and hardenability. The text then explores 3 percent nickel-chromium steel, 1 1⁄2 percent nickel-chromium-molybdenum steel, and 2 1⁄2 percent nickel-chromium-molybdenum steel (medium carbon). The manuscript takes a look at 2 1⁄2 percent nickel-chromium-molybdenum steel (high carbon) and 3 percent nickel-chromium-molybdenum steel. Topics include welding, machinability, hot working and heat treatment temperatures, continuous cooling transformation, hardenability, and physical properties. The text also ponders on 4 1⁄4 percent nickel-chromium steel (with or without molybdenum), 1 percent carbon-chromium steel, and carbon case-hardening steel. The publication is a dependable source material for readers interested in the mechanical and physical properties of steels.
Download or read book Theory of universal constants written by Khalid Jerrari and published by Khalid Jerrari. This book was released on 2022-09-07 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental laws of physics include fixed numerical parameters called "universal constants". These quantities, determined experimentally and supposed to vary neither in time nor in space, remain one of the greatest mysteries of science. Our current knowledge does not allow us to understand their origin nor to determine them in a theoretical way. In this book, the author is mainly interested in these elements. His approach is to build a theoretical framework that could explain the source of these constants in our laws of physics and to propose a method that would not only predict them all but also define them. To do this, the author begins by introducing the assumptions on which he bases his theory. Then, in a first part, he expresses the universal constants, the Planck units and the thermodynamic quantities of the Universe in terms of its characteristic variables, such as its mass and its radius. In a second part, he demonstrates the constancy of the Planck units as well as that of the universal constants and, finally, he proposes a general theoretical framework to determine them.
Download or read book Fundamental Constants written by Boris M. Menin and published by Cambridge Scholars Publishing. This book was released on 2019-02-27 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to one of the important areas of theoretical and experimental physics—the calculation of the accuracy of measurements of fundamental physical constants. To achieve this goal, numerous methods and criteria have been proposed. However, all of them are focused on identifying a posteriori uncertainty caused by the idealization of the model and its subsequent computerization in comparison with the physical system. This book focuses on formulating an a priori interaction between the level of a detailed description of a material object (the number of registered quantities) and the lowest uncertainty in measuring a physical constant. It contains the materials necessary for the optimal design of models describing a physical phenomenon. It will appeal to scientists and engineers, as well as university students.
