Physics of the Impossible: A Scientific Exploration Into the World of Phasers, Force Fields, Teleportation, and Time Travelby Michio Kaku
Synopses & Reviews
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:
"In this latest effort to popularize the sciences, City University of New York professor and media star Kaku (Hyperspace) ponders topics that many people regard as impossible, ranging from psychokinesis and telepathy to time travel and teleportation. His Class I impossibilities include force fields, telepathy and antiuniverses, which don't violate the known laws of science and may become realities in the next century. Those in Class II await realization farther in the future and include faster-than-light travel and discovery of parallel universes. Kaku discusses only perpetual motion machines and precognition in Class III, things that aren't possible according to our current understanding of science. He explains how what many consider to be flights of fancy are being made tangible by recent scientific discoveries ranging from rudimentary advances in teleportation to the creation of small quantities of antimatter and transmissions faster than the speed of light. Science and science fiction buffs can easily follow Kaku's explanations as he shows that in the wonderful worlds of science, impossible things are happening every day." Publishers Weekly (Copyright Reed Business Information, Inc.)
"In these discussions, Kaku not only explores impossibilities but, in doing so, elucidates some basic physics, so this book both teaches and challenges." Library Journal
"A physics professor at City University of New York, Kaku is also a respected popularizer of scientific theory, and he does a great job here of making concrete the heady abstractions necessary to our grasp of the physics behind these ideas." Seattle Times
"Mighty few theoretical physicists would bother expounding some of these possible impossibilities, and Kaku is to be congratulated for doing so, even if what he accomplishes here is only to get the juices of future physicists flowing." Los Angeles Times
Book News Annotation:
Kaku (theoretical physics, City University of New York), well known to viewers of science documentaries as an entertaining and understandable science interpreter, continues as such in this new book. He confesses his lifelong fascination with science fiction and the ideas of force fields, invisibility rays, hyperspeed space ships, time travel and more, and then examines each of these science fiction staples, concluding that one day we may manage almost all of them. Kaku writes in a conversational style with clear explanations of the physics involved. Happily, he also largely avoids irritating analogies, which generally confuse rather than clarify but are often used by scientists to explain their work to laymen. Kaku respects the intelligence of his readers, even if they haven't studied non-linear equations. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
The audacious effort to map the brainand#8212;and along with it our mental afflictions, from autism to schizophreniaand#8212;by a rising star in neuroscience.
We know that each of us is unique, but science has struggled to pinpoint where, precisely, our uniqueness resides. Is it in our genes? The structure of our brains? Our genome may determine our eye color and even aspects of our personality. But our friendships, failures, and passions also shape who we are. The question is: how? Sebastian Seung, a dynamic professor at MIT, is on a quest to discover the biological basis of identity. He believes it lies in the pattern of connections between the brainand#8217;s neurons, which change slowly over time as we learn and grow. The connectome, as itand#8217;s called, is where our genetic inheritance intersects with our life experience. Itand#8217;s where nature meets nurture. Seung introduces us to the dedicated researchers who are mapping the brainand#8217;s connections, neuron by neuron, synapse by synapse. It is a monumental undertakingand#8212;the scientific equivalent of climbing Mount Everestand#8212;but if they succeed, it could reveal the basis of personality, intelligence, memory, and perhaps even mental disorders. Many scientists speculate that people with anorexia, autism, and schizophrenia are "wired differently," but nobody knows for sure. The brainand#8217;s wiring has never been clearly seen. In sparklingly clear prose, Seung reveals the amazing technological advances that will soon help us map connectomes. He also examines the evidence that these maps will someday allow humans to "upload" their minds into computers, achieving a kind of immortality. Connectome is a mind-bending adventure story, told with great passion and authority. It presents a daring scientific and technological vision for at last understanding what makes us who we are. Welcome to the future of neuroscience.
The bold and thrilling quest to finally understand the brainandmdash;and along with it our mental afflictions, from depression to autismandmdash;by a rising star in neuroscience
Sebastian Seung, a dynamic young professor at MIT, is at the forefront of a revolution in neuroscience. He believes that our identity lies not in our genes, but in the connections between our brain cellsandmdash;our own particular wiring. Seung and a dedicated group of researchers are leading the effort to map these connections, neuron by neuron, synapse by synapse. It is a monumental effortandmdash;the scientific equivalent of climbing Mount Everestandmdash;but if they succeed, they will uncover the basis of personality, identity, intelligence, memory, and perhaps disorders such as autism and schizophrenia. Seung explains how this new map of a human andldquo;connectomeandrdquo; might even enable us to andldquo;uploadandrdquo; our brains into a computer, making us effectively immortal.
Connectomeis a mind-bending adventure story, told with great passion and authority. It presents a daring scientific and technological vision for at last understanding what makes us who we are, both as individuals and as a species.
