Physics of the Impossible: A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel

A fascinating exploration of the science of the impossible—from death rays and force fields to invisibility cloaks—revealing to what extent such technologies might be achievable decades or millennia into the future.

One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.

From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals—and the limits—of the laws of physics as we know them today. He ranks the impossible technologies by categories—Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:
· How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers “downstream”
· How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars
· How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology
· Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build one
Kaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.

The Field Updated Ed: The Quest for the Secret Force of the Universe

Science has recently begun to prove what ancient myth and religion have always espoused: There may be such a thing as a life force.

In this groundbreaking classic, investigative journalist Lynne McTaggart reveals a radical new paradigm—that the human mind and body are not separate from their environment but a packet of pulsating power constantly interacting with this vast energy sea, and that consciousness may be central in shaping our world.

The Field is a highly readable scientific detective story presenting a stunning picture of an interconnected universe and a new scientific theory that makes sense of supernatural phenomena. Documented by distinguished sources, The Field is a book of hope and inspiration for today's world.

A Brief History of Time

Stephen Hawking, one of the most brilliant theoretical physicists in history, wrote the modern classic A Brief History of Time to help nonscientists understand the questions being asked by scientists today: Where did the universe come from? How and why did it begin? Will it come to an end, and if so, how? Hawking attempts to reveal these questions (and where we're looking for answers) using a minimum of technical jargon. Among the topics gracefully covered are gravity, black holes, the Big Bang, the nature of time, and physicists' search for a grand unifying theory. This is deep science; these concepts are so vast (or so tiny) as to cause vertigo while reading, and one can't help but marvel at Hawking's ability to synthesize this difficult subject for people not used to thinking about things like alternate dimensions. The journey is certainly worth taking, for, as Hawking says, the reward of understanding the universe may be a glimpse of "the mind of God." --Therese Littleton

A Brief History of Time, published in 1988, was a landmark volume in science writing and in world-wide acclaim and popularity, with more than 9 million copies in print globally. The original edition was on the cutting edge of what was then known about the origins and nature of the universe. But the ensuing years have seen extraordinary advances in the technology of observing both the micro—and the macrocosmic world—observations that have confirmed many of Hawking's theoretical predictions in the first edition of his book.

Now a decade later, this edition updates the chapters throughout to document those advances, and also includes an entirely new chapter on Wormholes and Time Travel and a new introduction. It make vividly clear why A Brief History of Time has transformed our view of the universe.

Examkrackers: 1001 Questions in MCAT in Physics

This book contains 1001 fully annotated physics questions in the MCAT format organized by topic. The range of difficulty is from easy to very difficult. There are questions on every physics topic that might appear on the MCAT.

A Briefer History of Time

Stephen Hawking’s worldwide bestseller, A Brief History of Time, has been a landmark volume in scientific writing. Its author’s engaging voice is one reason, and the compelling subjects he addresses is another: the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the book’s most important concepts.

This is the origin of and the reason for A Briefer History of Time: its author’s wish to make its content more accessible to readers—as well as to bring it up-to-date with the latest scientific observations and findings.

Although this book is literally somewhat “briefer,” it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory.

This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the book—but even more so—A Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space.

Surely You're Joking, Mr. Feynman! (Adventures of a Curious Character)

A series of anecdotes shouldn't by rights add up to an autobiography, but that's just one of the many pieces of received wisdom that Nobel Prize-winning physicist Richard Feynman (1918-88) cheerfully ignores in his engagingly eccentric book, a bestseller ever since its initial publication in 1985. Fiercely independent (read the chapter entitled "Judging Books by Their Covers"), intolerant of stupidity even when it comes packaged as high intellectualism (check out "Is Electricity Fire?"), unafraid to offend (see "You Just Ask Them?"), Feynman informs by entertaining. It's possible to enjoy Surely You're Joking, Mr. Feynman simply as a bunch of hilarious yarns with the smart-alecky author as know-it-all hero. At some point, however, attentive readers realize that underneath all the merriment simmers a running commentary on what constitutes authentic knowledge: learning by understanding, not by rote; refusal to give up on seemingly insoluble problems; and total disrespect for fancy ideas that have no grounding in the real world. Feynman himself had all these qualities in spades, and they come through with vigor and verve in his no-bull prose. No wonder his students--and readers around the world--adored him. --Wendy Smith

The outrageous exploits of one of this century's greatest scientific minds and a legendary American original. In this phenomenal national bestseller, the Nobel Prize-winning physicist Richard P. Feynman recounts in his inimitable voice his adventures trading ideas on atomic physics with Einstein and Bohr and ideas on gambling with Nick the Greek, painting a naked female toreador, accompanying a ballet on his bongo drums and much else of an eyebrow-raising and hilarious nature. A New York Times bestseller; more than 500,000 copies sold.

The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory

There is an ill-concealed skeleton in the closet of physics: "As they are currently formulated, general relativity and quantum mechanics cannot both be right." Each is exceedingly accurate in its field: general relativity explains the behavior of the universe at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, believes that the two pillars of physics can be reconciled in superstring theory, a theory of everything.

Superstring theory has been called "a part of 21st-century physics that fell by chance into the 20th century." In other words, it isn't all worked out yet. Despite the uncertainties--"string theorists work to find approximate solutions to approximate equations"--Greene gives a tour of string theory solid enough to satisfy the scientifically literate.

Though Ed Witten of the Institute for Advanced Study is in many ways the human hero of The Elegant Universe, it is not a human-side-of-physics story. Greene's focus throughout is the science, and he gives the nonspecialist at least an illusion of understanding--or the sense of knowing what it is that you don't know. And that is traditionally the first step on the road to knowledge. --Mary Ellen Curtin

"[Greene] develops one fresh new insight after another...In the great tradition of physicists writing for the masses, The Elegant Universe sets a standard that will be hard to beat." --George Johnson, The New York Times Book Review

In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.

Green uses everything from an amusement park ride to ants on a garden hose to illustrate the beautiful yet bizarre realities that modern physics is unveiling.    Dazzling in its brilliance, unprecedented in its ability to both illuminate and entertain, The Elegant Universe is a tour de force of science writing-a delightful, lucid voyage through modern physics that brings us closer than ever to understanding how the universe works.

The Holographic Universe

Today nearly everyone is familiar with holograms, three-dimensional images projected into space with the aid of a laser. Now, two of the world's most eminent thinkers -- University of London physicists David Bohm, a former protege of Einstein's and one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, one of the architects of our modern understanding of the brain -- believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. This remarkable new way of looking at the universe explains now only many of the unsolved puzzles of physics, but also such mysterious occurrences as telepathy, out-of-body and near death experiences, "lucid" dreams, and even religious and mystical experiences such as feelings of cosmic unity and miraculous healings.

The Fabric of the Cosmos: Space, Time, and the Texture of Reality

As a boy, Brian Greene read Albert Camus' The Myth of Sisyphus and was transformed. Camus, in Greene's paraphrase, insisted that the hero triumphs "by relinquishing everything beyond immediate experience." After wrestling with this idea, however, Greene rejected Camus and realized that his true idols were physicists; scientists who struggled "to assess life and to experience the universe at all possible levels, not just those that happened to be accessible to our frail human senses." His driving question in The Fabric of the Cosmos, then, is fundamental: "What is reality?" Over sixteen chapters, he traces the evolving human understanding of the substrate of the universe, from classical physics to ten-dimensional M-Theory.

Assuming an audience of non-specialists, Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. For the most part, he succeeds. His language reflects a deep passion for science and a gift for translating concepts into poetic images. When explaining, for example, the inability to see the higher dimensions inherent in string theory, Greene writes: "We don't see them because of the way we see…like an ant walking along a lily pad…we could be floating within a grand, expansive, higher-dimensional space."

For Greene, Rhodes Scholar and professor of physics and mathematics at Columbia University, speculative science is not always as thorough and successful. His discussion of teleportation, for example, introduces and then quickly tables a valuable philosophical probing of identity. The paradoxes of time travel, however, are treated with greater depth, and his vision of life in a three-brane universe is compelling and--to use his description for quantum reality--"weird."

In the final pages Greene turns from science fiction back to the fringes of science fact, and he returns with rigor to frame discoveries likely to be made in the coming decades. "We are, most definitely, still wandering in the jungle," he concludes. Thanks to Greene, though, some of the underbrush has been cleared. --Patrick O'Kelley

From Brian Greene, one of the world’s leading physicists and author the Pulitzer Prize finalist The Elegant Universe, comes a grand tour of the universe that makes us look at reality in a completely different way.

Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

Quantum Enigma: Physics Encounters Consciousness

In trying to understand the atom, physicists built quantum mechanics and found, to their embarrassment, that their theory intimately connects consciousness with the physical world. Quantum Enigma explores what that implies and why some founders of the theory became the foremost objectors to it. Authors Bruce Rosenblum and Fred Kuttner explain all of this in non-technical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, with an emphasis on what is and what is not speculation. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is controversial. Every interpretation of quantum physics encounters consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum physics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing. Readers are brought to a boundary where the particular expertise of physicists is no longer a sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves.
