Yet recent theories suggest that there is far more to the universe than what our instruments record--in fact, it could be infinite. Colossal flows of galaxies, large empty regions called voids, and other unexplained phenomena offer clues that our own "bubble universe" could be part of a greater realm called the multiverse. How big is the observable universe? What it is made of? What lies beyond it? Was there a time before the Big Bang? Could space have unseen dimensions? In this book, physicist and science writer Paul Halpern explains what we know--and what we hope to soon find out--about our extraordinary cosmos.Explains what we know about the Big Bang, the accelerating universe, dark energy, dark flow, and dark matter to examine some of the theories about the content of the universe and why its edge is getting farther away from us fasterExplores the idea that the observable universe could be a hologram and that everything that happens within it might be written on its edgeWritten by physicist and popular science writer Paul Halpern, whose other books include "Collider: The Search for the World's Smallest Particles," and "What's Science Ever Done For Us: What the Simpsons Can Teach Us About Physics, Robots, Life, and the Universe"

    

    Traces the history of time from Augustine's suggestion that there is no time, to the flowing time of Newton, the static time of Einstein, and then back, to the idea that there is no time in quantum gravity.

    By replacing equations with diagrams, the book allows non-specialist readers to fully understand the concepts in relativity without the slow, painful progress so often associated with a complicated scientific subject. It allows readers not only to know how relativity works, but also to intuitively understand it.

    K. C. Cole's "Fun with Physics" is a profile of astrophysicist Janet Conrad that blends her personal life with professional activity. In "Desperate Measures," the doctor and writer Atul Gawande profiles the surgeon Francis Daniels Moore, whose experiments in the 1940s and '50s pushed medicine harder and farther than almost anyone had contemplated. Also included is a poem by the legendary John Updike, "Mars as Bright as Venus." The collection ends with Diane Ackerman's "ebullient" essay "We Are All a Part of Nature."Together these twenty-three articles on a wide range of today's most current topics in science -- from biology, physics, biotechnology, and astronomy, to anthropology, genetics, evolutionary theory, and cognition‚ represent the full spectrum of scientific writing from America's most prominent science authors, proving once again that "good science writing is evidently plentiful" (Scientific American).

    Using illustrations and examples from science fiction pulp magazines and comic books, The Amazing Story of Quantum Mechanics explains the fundamental principles of quantum mechanics that underlie the world we live in.Watch a Video

    It is now revised to reflect the most recent advances in physics. From black holes to holograms, from relativity theory to the discovery of quarks, this book is an original and rich exposition of quantum theory and the way it unravels profound theological questions.

    In the paper, Wigner observed that the mathematical structure of a physical theory often points the way to further advances in that theory and even to empirical predictions.

    1: Elementary Theory and Problems contains the essential material that is usually covered in required courses of strength of materials in our engineering schools. Strength of Materials - Part. 2: Advanced Theory and Problems contains the later developments that are of practical importance in the fields of strength of materials, and theory of elasticity. Complete derivations of problems of practical interest are given in most cases. The books are illustrated with a number of problems to which solutions are presented. In many cases, the problems are chosen so as to widen the field covered by the text and to illustrate the application of the theory in the solution of design problems.

    Second, it proposes that the inhabitants of this subterranean biosphere are not plants or animals as we know them, but heat-loving bacteria that survive on a diet consisting solely of hydrocarbons that is, natural gas and petroleum. And third and perhaps most heretically, the book advances the stunning idea that most hydrocarbons on Earth are not the byproduct of biological debris ("fossil fuels"), but were a common constituent of the materials from which the earth itself was formed some 4.5 billion years ago.The implications are astounding. The theory proposes answers to often-asked questions: Is the deep hot biosphere where life originated, and do Mars and other seemingly barren planets contain deep biospheres? Even more provocatively, is it possible that there is an enormous store of hydrocarbons upwelling from deep within the earth that can provide us with abundant supplies of gas and petroleum?However far-fetched these ideas seem, they are supported by a growing body of evidence, and by the indisputable stature and seriousness Gold brings to any scientific debate. In this book we see a brilliant and boldly original thinker, increasingly a rarity in modern science, as he develops potentially revolutionary ideas about how our world works.

     It’s the story about how a Chinese fishing village became a global economic powerhouse of innovation and technology. Just four decades ago Shenzhen was a backwater area, populated by fishermen and rice farmers. Today, it’s home to up to 20 million people and some of the world’s leading technology companies and most innovative tech startups. No other city better symbolizes the rise of modern China. And no other city challenges Silicon Valley more aggressively as the global hub for innovation and technology startups. In many ways, the Chinese city has already outsmarted the Valley. “Shenzhen has an energy of growth – the same energy I felt when I first came to Silicon Valley ten years ago. And it’s not just in technology. It’s this idea that whoever you are, whatever you’re into, you can come to China, and especially Shenzhen, and do it!” American entrepreneur Scotty Allen says in the book. Shenzhen Superstars is written for anyone who wants to be part of this raging growth story – no matter if you’re a tech buff, investor or just someone curious about knowing what’s driving the future. As a journalist for CNN, Forbes and other international media, Johan Nylander has witnessed the astonishing transformation of the south Chinese city. Its speed, energy and determination are just mind-blowing. His aim is to take you inside, to the very heart of what is shaping this vibrant city. KEY QUOTES FROM THE BOOK “In terms of hardware plus software innovation, Shenzhen is ahead of the curve.” – Jeffrey Towson, private equity investor and Peking University professor “The next ten years will be the era of robots and intelligent machines, and Shenzhen will play well to that.” – Jixun Foo, managing partner of GGV Capital “Shenzhen is just better than Silicon Valley in terms of hardware and software integration.” – Qin Li, CEO of startup Sennotech “If you’re not already in Shenzhen, you're crazy.” – Edith Yeung, general partner of 500 Startups

    In The Physics of Star Wars, you’ll explore the mystical power of the Force using quantum mechanics, find out how much energy it would take for the Death Star or Starkiller Base to destroy a planet, and discover how we can potentially create our very own lightsabers. The fantastical world of Star Wars may become a reality!

    The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader's understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology.
