From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. In On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity.Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy.Concise and precise, and infused with Zee's signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe.

    It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behaviour of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its intellectual giants, from Albert Einstein to Stephen Hawking, over the strange paradoxes and implications that seem like the stuff of fantasy. Whether it's Schr�dinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory is what challenges our fundamental assumptions about our reality. In Einstein's Unfinished Revolution, globally renowned theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved for the simple reason that the theory is incomplete. There is more, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond it to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed the field, before wrestling with the puzzles and conundrums that they present. Along the way, he illuminates the existing theories about the quantum world that might solve these problems, guiding us toward his own vision that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics as we know it to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

    Four Thousand Dogs.An incredible true story of rescue and redemption. When Keith Benning accepted the job as a deputy in a small North Dakota county, he had no idea he was about to face the biggest challenge of his life. Four years and four thousand dogs later, he lost his marriage, a fellow officer and nearly his own life. By rescuing seventy starving and unwanted animals out of his garage each month, Keith and a small team of volunteers have changed the world for thousands of dogs, and tens of thousands more to come. Woven with riveting and inspiring real-life rescue stories, Rescue Matters tells a larger tale of tragedy-meets-redemption. A gripping account of how a garage rescue grew into a mighty force that inspired a nation.C.J. English shares her personal experience inside the emotional and bittersweet world of dog rescue, delivering a heart-wrenching and deeply moving story that has much to teach us about responsibility and compassion. Rescue Matters is alive with meaning and purpose, proving that that it doesn’t take a law or government to change the world, all it takes is a few people trying to make a difference to start a revolution. Not just for dog lovers, but for anyone inspired by the compassion of humans and the resilience of the animals who forgive them. 50% of the profits from the sale of this book will go directly back to Keith Benning and his team at Turtle Mountain Animal Rescue.

    Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched. This is not some alternative universe but the realm of the very small, where quantum mechanics rules. In this weird world of atoms and their constituents, our common sense understanding of reality breaks down - yet quantum mechanics has never failed an experimental test. What does it all mean? For all its weirdness, quantum mechanics has given us many practical technologies including lasers and the transistors that underlie computers and all digital technology. In the future, it promises computers more powerful than any built before, the ability to communicate with absolute privacy, and even quantum teleportation. The Quantum World explores the past, present and future of quantum science, its applications and mind-bending implications. Discover how ideas from quantum mechanics are percolating out into the vast scale of the cosmos - perhaps, in the future, to reveal a new understanding of the big bang and the nature of space and time.ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds.

    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.

    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.

    Time is simply how you live your life.” —Craig SagerThanks to an eccentric wardrobe filled with brightly-colored suits and a love of sports that knows no bounds, Craig Sager is one of the most beloved and recognizable broadcasters on television. So when the sports world learned that he was diagnosed with acute myeloid leukemia (AML) there was an outpouring of love and support from everyone who was inspired by his colorful life and his fearless decision to continue doing the job he loved—despite being told that he would have only three-to-six months to live. Since then Sager has undergone three stem cell transplants—with his son as the donor for two of them—and more than twenty chemotherapy cycles.In Living Out Loud, Craig Sager shares incredible stories from his remarkable career and chronicles his heroic battle. Whether he’s sprinting across Wrigley Field mid-game as a college student with cops in pursuit, chasing down Hank Aaron on the field for an interview after Aaron broke Babe Ruth’s home run record, running with the bulls in Pamplona, or hunkering down to face the daunting physical challenges of fighting leukemia, Craig Sager is always ready to defy expectations, embrace life, and live it to the fullest.Including a foreword by Charles Barkley and with unique insight from his son Craig Sager II, this entertaining, honest, and introspective account of a life lived in sports reveals the enduring lessons Sager has learned throughout his career and reminds you that no matter what life throws at you, to always look at the bright side.
