"Outstanding Academic Title for 2014" by CHOICE Einstein Relatively Simple brings together for the first time an exceptionally clear explanation of both special and general relativity. It is for people who always wanted to understand Einstein's ideas but never thought they could. Told with humor, enthusiasm, and rare clarity, this entertaining book reveals how a former high school drop-out revolutionized our understanding of space and time. From E=mc2 and everyday time travel to black holes and the big bang, Einstein Relatively Simple takes us all, regardless of our scientific backgrounds, on a mind-boggling journey through the depths of Einstein's universe. Along the way, we track Einstein through the perils and triumphs of his life — follow his thinking, his logic, and his insights — and chronicle the audacity, imagination, and sheer genius of the man recognized as the greatest scientist of the modern era. In Part I on special relativity we learn how time slows and space shrinks with motion, and how mass and energy are equivalent. Part II on general relativity reveals a cosmos where black holes trap light and stop time, where wormholes form gravitational time machines, where space itself is continually expanding, and where some 13.7 billion years ago our universe was born in the ultimate cosmic event — the Big Bang.

Most popular science books give general relativity only a brief mention or ignore it altogetherReviews: “This general relativity theory changed our views on the origin and on the ending (if any) of the universe … all topics that tickle the imagination of a general public and Egdall, bringing the reader to the point beyond general relativity, does not miss the opportunity to end his guided tour with a sparkling firework of these issues … it is an entertaining introduction for the layman, that brings the reader a very long way.” The European Mathematical Society “He covers the main topics of special and general relativity in a refreshing, personal way. This is a well-crafted, well-documented text with extensive endnotes, in which a bibliography is embedded. He introduces readers to his own unique entry into this very populous genre. Valuable for inquisitive nonscientists.” CHOICE “I'm crazy about it. It's the best presentation of relativity for non-scientists that I've seen.” Art Hobson Professor Emeritus of Physics University of Arkansas "The writing is jovial and energetic and holds the reader's attention. This book is a nice introduction to modern physics, with a great biography of Einstein included. This book is recommended for a lay reader with basic algebra skills; high school and beginning college physics students would find it easily accessible." Zentralblatt MATH

The idea of a multiple universe reality is no longer considered speculative or implausible by many physicists; rather, it is deemed inescapable. Distinct concepts of the multiverse spring from quantum mechanics, cosmology, string theory-based cosmology, and ideas about a mathematics based reality that borders on the religious. In this accessible and entertaining book, Dr. Manly guides you on a tour of the many multiverse concepts and provides the non-technical background to understand them. Visions of the Multiverse explores questions such as: Just what is a multiverse? What are the different concepts of the multiverse and how are they related? Is it possible to determine if we live in a multiverse...or even in multiple types of multiverses? How do religious concepts of the afterlife and popular ideas based on the Law of Attraction relate to the scientific visions of the multiverse? Dr. Manly discusses a wide variety of fascinating concepts from relativity and the fundamental particles and forces of nature to dark matter, dark energy, and quantum mechanics in an unintimidating and conversational tone. Is humanity is in the midst of a new Copernican revolution? You decide.

What do modern multiverse theories and spiritualist séances have in common? Not much, it would seem. One is an elaborate scientific theory developed by the world’s most talented physicists. The other is a spiritual practice widely thought of as backward, the product of a mystical world view fading under the modern scientific gaze. But Christopher G. White sees striking similarities. He does not claim that séances or other spiritual practices are science. Yet he points to ways that both spiritual practices and scientific speculation about multiverses and invisible dimensions are efforts to peer into the hidden elements and even the existential meaning of the universe. Other Worlds examines how the idea that the universe has multiple, invisible dimensions has inspired science fiction, fantasy novels, films, modern art, and all manner of spiritual thought reaching well beyond the realm of formal religion. Drawing on a range of international archives, White analyzes how writers, artists, filmmakers, televangelists, and others have used the scientific idea of invisible dimensions to make supernatural phenomena such as ghosts and miracles seem more reasonable and make spiritual beliefs possible again for themselves and others. Many regard scientific ideas as disenchanting and secularizing, but Other Worlds shows that these ideas—creatively appropriated in such popular forms as C. S. Lewis’s Chronicles of Narnia, the art of Salvador Dalí, or the books of the counterculture physicist “Dr. Quantum”—restore a sense that the world is greater than anything our eyes can see, helping to forge an unexpected kind of spirituality.

When the fuzzy indeterminacy of quantum mechanics overthrew the orderly world of Isaac Newton, Albert Einstein and Erwin Schrödinger were at the forefront of the revolution. Neither man was ever satisfied with the standard interpretation of quantum mechanics, however, and both rebelled against what they considered the most preposterous aspect of quantum mechanics: its randomness. Einstein famously quipped that God does not play dice with the universe, and Schrödinger constructed his famous fable of a cat that was neither alive nor dead not to explain quantum mechanics but to highlight the apparent absurdity of a theory gone wrong. But these two giants did more than just criticize: they fought back, seeking a Theory of Everything that would make the universe seem sensible again. In Einstein’s Dice and Schrödinger’s Cat, physicist Paul Halpern tells the little-known story of how Einstein and Schrödinger searched, first as collaborators and then as competitors, for a theory that transcended quantum weirdness. This story of their quest—which ultimately failed—provides readers with new insights into the history of physics and the lives and work of two scientists whose obsessions drove its progress. Today, much of modern physics remains focused on the search for a Theory of Everything. As Halpern explains, the recent discovery of the Higgs Boson makes the Standard Model—the closest thing we have to a unified theory— nearly complete. And while Einstein and Schrödinger failed in their attempt to explain everything in the cosmos through pure geometry, the development of string theory has, in its own quantum way, brought this idea back into vogue. As in so many things, even when they were wrong, Einstein and Schrödinger couldn’t help but get a great deal right.

God Probability And Life After Death

God, Probability and Life after Death reveals its objective in its title, namely, to present an exploratory argument concerning the probability of human resurrection. The exploratory argument follows a probabilistic passage along an evidential trail to the discovery of the probability of life after death. It is a trail that the reader can personally engage with in order to reach their own conclusion and even introduce additional evidence they think relevant. The argument begins with the probability of the existence of God, and once a position is established on this issue, the argument becomes empowered for the next stage, which is to address the evidence for human resurrection, namely, the Resurrection of Jesus, near-death experiences and apparitions. The probabilistic relationship between the evidence and the resurrection hypothesis is critically examined throughout the book by engaging the potential views of an atheist and agnostic in addition to that of a theist. On this probabilistic journey, other issues relevant to the resurrection argument are introduced, such as personal identity and the possibility of resurrection given the nature of our world. Evidence and argument for a non-supernatural possibility for human resurrection are also considered. Significantly, the author does not assume the normal spiritual approach to human resurrection, when a disembodied soul leaves the body to continue a spiritual existence in a ghostly realm. Instead, a materialistic approach is taken, whereby the resurrected person survives in bodily form in a physical realm. The use of probability theory is intended to keep the evidential argument within the bounds of coherent reasoning. It also enables the argument to link one piece of evidence to the next in a probabilistic sequence that eventually leads to the conclusion that human resurrection is not only possible, it is also very likely.
