The Young Universe presents four major physical and astrophysical themes related to these extreme phases of the primordial universe. In particular, it presents the physics of the primordial plasma and the concepts of quantum and particle physics necessary to describe this extreme state. It discusses the cosmological background radiation and explores inflation, an extremely rapid expansion phase that is believed to have occurred very early in cosmological history and to have shaped our present universe. The book also provides a synthesis of the dark matter problem.
Lively and authoritative, this survey by a renowned physicist explains the formation of the galaxies and defines the concept of an ever-expanding universe in simple terms. 1961 edition. 40 figures.
For over three millennia, most people could understand the universe only in terms of myth, religion, and philosophy. Between 1920 and 1970, cosmology transformed into a branch of physics. With this remarkably rapid change came a theory that would finally lend empirical support to many long-held beliefs about the origins and development of the entire universe: the theory of the big bang. In this book, Helge Kragh presents the development of scientific cosmology for the first time as a historical event, one that embroiled many famous scientists in a controversy over the very notion of an evolving universe with a beginning in time. In rich detail he examines how the big-bang theory drew inspiration from and eventually triumphed over rival views, mainly the steady-state theory and its concept of a stationary universe of infinite age. In the 1920s, Alexander Friedmann and Georges Lemaître showed that Einstein's general relativity equations possessed solutions for a universe expanding in time. Kragh follows the story from here, showing how the big-bang theory evolved, from Edwin Hubble's observation that most galaxies are receding from us, to the discovery of the cosmic microwave background radiation. Sir Fred Hoyle proposed instead the steady-state theory, a model of dynamic equilibrium involving the continuous creation of matter throughout the universe. Although today it is generally accepted that the universe started some ten billion years ago in a big bang, many readers may not fully realize that this standard view owed much of its formation to the steady-state theory. By exploring the similarities and tensions between the theories, Kragh provides the reader with indispensable background for understanding much of today's commentary about our universe.

This is the story of the cosmic background radiation, the "afterglow" of the Big Bang in which the Universe was born. Fifteen billion years after the event, the afterglow still permeates all of space, making it the oldest relic in creation and providing an imprint of the Universe as it was in its infancy. But the most astonishing thing about the afterglow of creation is that it wasn't discovered until 1965, and then only by accident - despite the fact that it had been predicted in 1948 and the technology to detect it existed during World War II. Chown brilliantly weaves a tale of the search for the origins of the Universe. Beginning in the 1920s and culminating with the flight of the COBE satellite and what it found, this book uncovers the secrets of the Universe.
Riddled with jealousy, rivalry, missed opportunities and moments of genius, the history of the atom's discovery is as bizarre, as capricious, and as weird as the atom itself. John Dalton gave us the first picture of the atom in the early 1800s. Almost 100 years later the young misfit New Zealander, Ernest Rutherford, showed the atom consisted mostly of space, and in doing so overturned centuries of classical science. It was a brilliant Dane, Neils Bohr, who made the next great leap - into the incredible world of quantum theory. Yet, he and a handful of other revolutionary young scientists weren't prepared for the shocks Nature had up her sleeve. This 'insightful, compelling' book ( New Scientist) reveals the mind-bending discoveries that were destined to upset everything we thought we knew about reality and unleash a dangerous new force upon the world. Even today, as we peer deeper and deeper into the atom, it throws back as many questions at us as answers.
“Think Run Lola Run by way of the Columbine massacre. . . . A noir steeped in teenage misery and revenge” by the author of Sensation and Sabbath (Backlisted). Every day, Dave Holbrook runs the gauntlet of high school in northern New Jersey, complete with racial tensions, bullying, and outright violence. His home life isn’t so great either. His mother’s an alcoholic and his father can’t be bothered. So Dave subsists on over-the-counter cough syrup and his love for her . . . She’s a transfer student, a waitress, a goddess of discord named Eris. And she offers Dave a way out of his miserable existence—and into an infinite number of tragically short lives. In one, he dies of bronchitis as a baby. In another, he has a job installing lottery machines until a fatal car wreck. And in the darkest one of all, he arms himself with an Uzi and walks into his school. No matter what happens, it seems, Dave is trapped on a never-ending ride of infinite possibilities—with Eris at the wheel. “Nick Mamatas’s work is often so relevant and timely as to border on the prophetic, and his fourth solo novel is no exception. It may also be his most accessible book to date, which is all the more impressive when you consider its non-linear, unique structure, and the Gus Van Sant-sized elephant in the classroom—Bullettime centers around a miserable teenager shooting up his high school.” —Strange Horizons “Complex, ambitious . . . Readers willing to venture off the beaten path will be intrigued by Dave’s sometimes pathetic and sometimes oddly endearing life stories.” —Publishers Weekly “Mamatas’s strong voice shines.” —SF Signal
SCIENCE WRITER EDWARD MACDOWELL HAS NEVER HAD ANY INTEREST IN THE SUPERNATURAL. As an open-minded skeptic, he assumes that all extraordinary events, no matter how baffling, can be explained rationally, given enough information. When a strange, hallucinatory encounter prompts him to investigate a haunting, he does so convinced the alleged ghost is at most nothing more than a rare optical phenomenon. But what he discovers will shatter that conviction, overturn all his assumptions about reality, and ultimately send him off on a desperate journey to- and beyond- the furthest reaches of our Universe. Before it is done, Edward and the woman he loves find themselves crossing unimagined dimensional barriers into bizarre other realms of existence while fighting for their very lives against an ancient, inhuman evil. The final confrontation will present them with a challenge no Humans have ever met, and lead them to a goal none have ever reached.
With stunning regularity, the search for our cosmic roots has been yielding remarkable new discoveries about the universe and our place in it. In his compelling book, Origins: The Quest for Our Cosmic Roots, veteran science journalist Tom Yulsman chronicles the latest discoveries and describes in clear and engaging terms what they mean.
