Book Description
Einstein's gravity theory—his general theory of relativity—has served as the basis for a series of astonishing cosmological discoveries. But what if, nonetheless, Einstein got it wrong? Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have. Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The capstone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work challenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence. This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.

Book Description
On the night of March 26, 1938, nuclear physicist Ettore Majorana boarded a ship, cash and passport in hand. He was never seen again. In A Brilliant Darkness, theoretical physicist Joao Magueijo tells the story of Majorana and his research group, "the Via Panisperna Boys," who discovered atomic fission in 1934. As Majorana, the most brilliant of the group, began to realize the implications of what they had found, he became increasingly unstable. Did he commit suicide that night in Palermo? Was he kidnapped? Did he stage his own death? A Brilliant Darkness chronicles Majorana's invaluable contributions to science -- including his major discovery, the Majorana neutrino -- while revealing the truth behind his fascinating and tragic life.

Book Description
Its About Time presents an introduction to theoretical physics as well as challenges to some of the concepts put forward by theoretical physicists of our time. These scientists have presented such concepts in countless public lectures, highlights of which are compiled here along with a variety of historical data, such as the history of earth time. Also included are short biographies of physicists who have contributed significantly to our knowledge base. To help foster understanding of the related astronomical matters, Its About Time includes technical information relating to Newton and Keplers laws. Technical discussions are appended to the end of each relevant chapter. Furthermore, it offers a credible and significant challenge to Einsteins theories and to the current thinking on time dilation. Finally, the study outlines some procedural guidelines for young physicists and suggests how academic institutions can become custodians of a central depository of reference data, facilitating future physicists into more efficient and fruitful endeavors. This study offers no challenge to mathematics, which is a pure and exact science. When a physicist is able to have the mathematics represent natural phenomena, then mathematics becomes a necessary tool for our simplified understanding of nature. Eventually all of nature will be reduced to mathematical terms. The challenge presented here is to theoretical mathematics with no proven relationship to natural phenomena.

Book Description
Gravity is the most detectable physical phenomenon of the universe. Nothing or nobody can escape its grasp, even in very large, astronomical distances. It is manifested in many aspects of our lives. Yet we are still not really sure what carries it. The gradually increasing understanding of gravity throughout history and its observed effects in various physical fields are the subjects of this book. This is an enlightening read about one of the most misterious phenomena of our lives that is still far from being fully understood, presenting a historical journey through several millennia of encountering and understanding gravity's mysteries.

Book Description
"Honorable mention – Biomedicine and Neuroscience, 2011 Prose Awards" An examination of how the cell should be described in order to effectively process biological data "The fruitful pursuit of biological knowledge requires one to take Einstein's admonition [on science without epistemology] as a practical demand for scientific research, to recognize Waddington's characterization of the subject matter of biology, and to embrace Wiener's conception of the form of biological knowledge in response to its subject matter. It is from this vantage point that we consider the epistemology of the cell." —from the Preface In the era of high biological data throughput, biomedical engineers need a more systematic knowledge of the cell in order to perform more effective data handling. Epistemology of the Cell is the first authored book to break down this knowledge. This text examines the place of biological knowledge within the framework of science as a whole and addresses issues focused on the specific nature of biology, how biology is studied, and how biological knowledge is translated into applications, in particular with regard to medicine. The book opens with a general discussion of the historical development of human understanding of scientific knowledge, the scientific method, and the manner in which scientific knowledge is represented in mathematics. The narrative then gets specific for biology, focusing on knowledge of the cell, the basic unit of life. The salient point is the analogy between a systems-based analysis of factory regulation and the regulation of the cell. Each chapter represents a key topic of current interest, including: Causality and randomness Translational science Stochastic validation: classification Stochastic validation: networks Model-based experimentation in biology Epistemology of the Cell is written for biomedical researchers whose interests include bioinformatics, biological modeling, biostatistics, and biological signal processing.

Book Description
Before the era of the specialist scientist, physical reality as a whole was the purview of the natural philosopher. This work is one of natural philosophy. Since the commencement of the twentieth century, science has became inundated with counter intuitive concepts. However, all genuine natural philosophy is based on man’s intuitive realism which evolved for the purpose of enabling homo sapiens to understand physical reality through sensory experience. The genesis of the concepts of genuine intuitive realism is the unconscious in which ongoing and stored sensory experience are analysed and intuitive realistic concepts are transferred to the mind purged of the specialised sciences at variance with physical realism Consequently, it has been my preoccupation for many years, to study with growing disparagement, those many concepts of the specialised sciences which, from the beginning of the twentieth century, run counter to intuitive realism. Examples of concepts countering intuitive realism are; that motion dilates time and contracts lengths; that time and space are not separate but welded together; a particular particle creates mass in particles without mass; that there are a multitude of dimensions which are invisible because they are tightly rolled up; that a body can be at two places at the same time; that what we see is not physical reality but a rendition of that reality in our brain and that a horse shoe can make a blacksmith. It is time that intuition is credited with the praise it deserves and there needs to be a cutting down to size of counter intuitive science. I have examined and revealed flaws in such prevailing counter intuitive realistic theories as special relativity; general relativity; QED; the standard model of micro particles; string theory; cerebral visual rendition, and natural selection. I propose alternative natural philosophic concepts which do not conflict with intuitive realism. I present this work in five chapters, with an epilogue, under the umbrella title of Effective Realism or In Praise of Intuition. Intuitive realism is the bedrock of Effective Realism and this work proclaims its effectiveness.

Book Description
New York Times best-selling author Caroline Myss draws from her years as a medical intuitive to show that healing is not only physical; it is also a mystical phenomenon that transcends reason. Inspired by ordinary people who overcame a wide array of physical and psychological ailments—from rheumatoid arthritis to cancer—Caroline dove into the works of the great mystics to gain a deeper understanding of healing’s spiritual underpinnings. Based on these studies, she demonstrates how conventional and holistic medicine often fall short in times of need. Both systems rely upon a logical approach to curing illness when there is nothing reasonable about the emotional, psychological, or spiritual influences behind any ailment. Integral to this mystical healing approach is the engagement of the soul, which we experience through exploring our seven shadow passions, building an empowered inner self around our seven inherent graces, and learning how to work with the mystical laws that govern it. This knowledge holds the key to understanding what it means to defy gravity and break through the boundaries of ordinary thought. You can heal any illness. You can channel grace. And you can learn to live fearlessly.

Book Description
Included in Library Journal’s "25 Key Indie Fiction Titles, Fall 2014-Winter 2015" Within the writer's life, words and things acquire power. For Borges it is the tiger and the color red, for Cortázar a pair of amorous lions, and for an early Egyptian scribe the monarch butterfly that metamorphosed into the Key of Life. Ducornet names these powers The Deep Zoo. Her essays take us from the glorious bestiary of Aloys Zötl to Abu Ghraib, from the tree of life to Sade's Silling Castle, from The Epic of Gilgamesh to virtual reality. Says Ducornet, "To write with the irresistible ink of tigers and the uncaging of our own Deep Zoo, we need to be attentive and fearless—above all very curious—and all at the same time." "Ducornet’s skill at drawing unexpected connections, and her ability to move between outrage and meditativeness, are gripping to behold."—Star Tribune

Book Description
Relativity theory has become one of the icons of Twentieth Century science. It's reckoned to be a difficult subject, taught as a layered series of increasingly difficult mathematics and increasingly abstract concepts. We're told that relativity theory is supposed to be this complicated and counter-intuitive. But how much of this historical complexity is really necessary? Can we bypass the interpretations and paradoxes and pseudoparadoxes of Einstein's special theory and jump directly to a deeper and more intuitive description of reality? What if curvature is a fundamental part of physics, and a final theory of relativity shouldn't reduce to Einstein's "flat" 1905 theory //on principle//? "Relativity..." takes us on a whistlestop tour of Twentieth Century physics - from black holes, quantum mechanics, wormholes and the Big Bang to the workings of the human mind, and asks: what would physics look like without special relativity? 394 printed pages, 234156 mm, 200 figures and illustrations, includes bibliography and index www.relativitybook.com
