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.

The speed of light, the fine structure constant, and Newton's constant of gravity — these are just three among the many physical constants that define our picture of the world. Where do they come from? Are they constant in time and across space? In this book, physicist and author Harald Fritzsch invites the reader to explore the mystery of the fundamental constants of physics in the company of Isaac Newton, Albert Einstein, and a modern-day physicist. The conversation that the three scientists are imagined to have provides an entertaining introduction to the constants and covers topics ranging from atomic, nuclear, and particle physics to astrophysics and cosmology.

Fundamental physical constants are used throughout the world by scientists and technologists in the course of every kind of theoretical and experimental research work. The book examines the present state of the measurement arts, and gives indications of likely future developments. This comprehensive and stimulating volume will certainly become a standard reference work in the field of measurement science for physicists, metrologists and workers in other physical science disciplines where a high accuracy of measurement is required.

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.

How did a single "genesis event" create billions of galaxies, black holes, stars and planets? How did atoms assemble -- here on earth, and perhaps on other worlds -- into living beings intricate enough to ponder their origins? What fundamental laws govern our universe?This book describes new discoveries and offers remarkable insights into these fundamental questions. There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.
