A Writer's Guide to the Real Science of Plausible Time Travel
From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favourite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That's just what Paul J. Nahin's guide provides.An ......
Investigates the worlds of visual thinking, insight, and creativity made possible by computer graphics and information visualisation technologies. This book argues that, with the spread of powerful computers, we are moving from a world based on words and numbers to a world where high level work in all fields involves insights based on computers.
Presents Newton's mathematical principles relating to natural philosophy and his system of the world. This book includes chapters relative to the motion of bodies; motion of bodies in resisting mediums; and system of the world in mathematical treatment; a section on axioms or laws of motion, and definitions.
In its search for causal explanations, modern science has increasingly come to focus on particles, genes, and other hypothetical elements that lie beyond direct human experience. This reductionist approach has led to powerful new technologies, but it has failed to give us an understanding of nature as we can actually experience it in its richness ......
Suitable for those fascinated by how physics explains the universe and affects philosophy. The author's in-depth presentation, complete with an appendix of mathematical formulas, makes accessible to lay readers findings normally available only to professional scientists.
Understanding tensors is essential for any physics student dealing with phenomena where causes and effects have different directions. A horizontal electric field producing vertical polarisation in dielectrics; an unbalanced car wheel wobbling in the vertical plane while spinning about a horizontal axis; an electrostatic field on Earth observed to ......
Physicists call the eternal, ubiquitous constancy of the laws of physics symmetry. Symmetry is the basic underlying principle that defines the laws of nature and hence controls the universe. This book explains the supremely elegant concept of symmetry and its profound ramifications to life on Earth and the universe at large.
Stephen Hawking was one of the most important astrophysicists of the last fifty years. After the publication of A Brief History of Time, he became an international celebrity. Though the book sold in the millions, few readers really grasped the significance of his groundbreaking work. Now popular Austrian science blogger Florian Freistetter, ......
Stephen Hawking's decades-long struggle with ALS (Lou Gehrig's disease), combined with his singular brilliance as a cosmologist, has fascinated both the public and his colleagues in science. This work explains Hawking's complex scientific accomplishments, while telling the story of his challenging life. It also discusses his personal life.
