In the world of physics, very little in the universe is what it first appears to be. And science fiction has imagined some pretty wild ideas about how the universe could work – from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared with the mind-bending science now coming out of physics and astronomy, and in this eBook, Physics: New Frontiers, we look at the strange and fascinating discoveries shaping (and reshaping) the field today. In the world of astrophysics, the weirdness begins at the moment of creation. In “The Black Hole at the Beginning of Time,” the authors discuss theories of what might have come before the big bang. Could our 3-D universe have sprung from the formation of a black hole in a 4-D cosmos? The math says: maybe. Later, in “The Giant Bubbles of the Milky Way,” the authors describe massive structures dubbed “Fermi bubbles” at its center – structures that no one noticed until recently. Technological innovations make much of this new science possible, as we see again in “Neutrinos at the Ends of the Earth,” where 5,000-odd sensors frozen deep within a cubic kilometer of ice in Antarctica aim to catch neutrinos in order to study distant cosmic phenomena. Scientists are also dissecting molecules with the most powerful x-ray laser in the world, as explored in “The Ultimate X-ray Machine.” Even our most fundamental notions of what reality is are up for debate, as examined in “Does the Multiverse Really Exist?” and the aptly named “What Is Real?” in which the authors question whether particles are indeed material things at all. While all of this abstraction might seem like a fun exercise in mental gymnastics, living things must also abide by the laws of physics, which, according to “The Limits of Intelligence,” may prevent our brains from evolving further. Then again, as we’ve learned, things could be different than they appear...

Organisms endowed with life show a sense of awareness, interacting with and learning from the universe in and around them. Each level of interaction involves transfer of information of various kinds, and at different levels. Each thread of information is interlinked with the other, and woven together, these constitute the universe — both the internal self and the external world — as we perceive it. They are, figuratively speaking, Nature's longest threads. This volume reports inter-disciplinary research and views on information and its transfer at different levels of organization by reputed scientists working on the frontier areas of science. It is a frontier where physics, mathematics and biology merge seamlessly, binding together specialized streams such as quantum mechanics, dynamical systems theory, and mathematics. The topics would interest a broad cross-section of researchers in life sciences, physics, cognition, neuroscience, mathematics and computer science, as well as interested amateurs, familiarizing them with frontier research on understanding information transfer in living systems.

Man’s intensifying use of the Earth’s habitat has led to an urgent need for scientifically advanced ‘geo-prediction systems’ that accurately locate subsurface resources and forecast the timing and magnitude of earthquakes, volcanic eruptions and land subsidence. As advances in the earth sciences lead to process-oriented ways of modeling the complex processes in the solid Earth, the papers in this volume provide a survey of some recent developments at the leading edge of this highly technical discipline. The chapters cover current research in predicting the future behavior of geologic systems as well as the mapping of geologic patterns that exist now in the subsurface as frozen evidence of the past. Both techniques are highly relevant to humanity’s need for resources such as water, and will also help us control environmental degradation. The book also discusses advances made in seismological methods to obtain information on the 3D structure of the mantle and the lithosphere, and in the quantitative understanding of lithospheric scale processes. It covers recent breakthroughs in 3D seismic imaging that have enhanced the spatial resolution of these structural processes, and the move towards 4D imaging that measures these processes over time. The new frontier in modern Earth sciences described in this book has major implications for oceanographic and atmospheric sciences and our understanding of climate variability. It brings readers right up to date with the research in this vital field.

Evolution of Particle Physics is concerned with the birth of particle physics and its maturation as a scientific field, with emphasis on advances in both theory and experiment. Topics covered include weak interactions and the breaking of hadron symmetries; the role of complexity in nature; symmetry principles in physics; and isobaric analog resonances in phenomenological nuclear spectroscopy. Adiabatic transformations as well as range and straggling of muons are also discussed. This book is comprised of 24 chapters and begins with a review of some of the most important discoveries in particle physics, along with the tools and techniques that made it possible. The reader is then introduced to symmetry breaking, paying particular attention to hadron symmetries and their connection to weak interactions. The following chapters explore channeling of ultrarelativistic charged particles in crystals; coherent scattering of high-energy hadrons by light nuclei; elementary particle physics and high-energy physics; and the design and use of large electron synchrotrons. This monograph will be of interest to particle physicists.

The story of physicists' quest to answer a mind-boggling question: How can we travel through time? Since H. G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics. Some images in the ebook are not displayed owing to permissions issues.
