Book Description
Just as the circle number π or the Euler constant e determines mathematics, fundamental constants of nature define the scales of the natural sciences. This book presents a new perspective by means of a few axioms and compares the resulting validity with experimental data. By the axiomatic approach Sommerfeld's mysterious fine-structure constant and Dirac's cosmic number are fixed as pure number constants. Thanks to these number constants, it is possible to calculate the value for the anomalous magnetic-moment of the electron in a simple way compared to QED calculations. With the same number constants it is also possible to calculate masses, partial lifetimes, magnetic-moments or charge radii of fundamental particles. The expressions used for the calculations, with few exceptions, yield values within the experimental error limits of the Particle Data Group. The author shows that the introduced number constants give even better predictions than the complicated QED calculations of today's doctrine. In the first part only experimental data from the literature for checking the postulates are used. In the second part the author explains electrical transport measurements with emergent behaviour, which were carried out in a professional environment.

Book Description
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.

Book Description
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.

Book Description
A standard reference that provides, in accessible form, selected critical data for professional and student solid Earth and planetary geophysicists. It represents the third version of the popular "Handbook of Physical Constants" (the first was published in 1942, the second in 1966). The present version reflects the enormous growth of scientific knowledge of the Earth and planets since 1966, spurred by the discovery and verification of plate tectonics and the systematic exploration of the solar system.

Book Description
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.

Book Description
"Mission is handicapped without a sound biblical theology of mission and an understanding of the history of mission leading up to our current context. Constants in Context offers both of these elements. It is mission theology in historical perspective and/or a history of mission that is grounded theologically. The authors describe it as a systematic theology with mission at its core, and a church history shaped by the constant but always contextual Christian traditions. Furthermore it is a constructive contribution to how mission theology needs to be practical and lived out through today's church and in our world. Written collaboratively by Roman Catholic writers Stephen Bevans and Roger Schroeder, both Missionaries of the Divine Word (SVDs). It is a particularly insightful in regard to the history and the various streams of Catholic mission but it also addresses and learns from the other traditions of the church. In fact, one of the book's strengths is its attention to neglected aspects and hidden stories of church and mission history. As a result it is gratifying to be inspired by non-European mission, women in mission and various forgotten or often ignored branches of the church. The book is in three sections: first, there is a framework for cultural contexts and theological constants; second, an in-depth exploration of historical stages and different models for mission; and third, a presentation of theological frameworks for mission. The third section concludes with a case for 'mission as prophetic dialogue' being the most appropriate model for 21st century mission." -- Amazon.com.
