Pressestimmen


"[Roger Penrose is] one of the greatest mathematical physicists alive....A work of breathtaking scope and richness....One certainly comes away from the book exhilarated by new metaphysical vistas."--The Wall Street Journal


"Provocative."--American Scientist


"Penrose reveals several worlds that are normally very hard to see but that thanks to his guidance are thrilling to imagine."--The New York Times

Synopsis

The motivation for this book arose, in part, from a need for detailed replies to a number of queries and criticisms from readers of the author's previous book, The Emperor's New Mind , many of whom have gone to extraordinary lengths to avoid the conclusion that there must be something non-computational involved in thinking. Penrose searches for a means, within the constraints of the hard facts of science, whereby a scientifically describable brain might be able to perform the needed non-computational actions. He develops the argument of how quantum effects might have a fundamental relevance to consciousness and to non-computable brain action. Some of the more startling implications of this are based on new scientific information which is discussed in detail, leading to one of the most extraordinary and fundamental implications of quantum theory: quantum entanglement, the process by which the behaviour of `classically' described systems is explicable only in quantum mechanical terms. There is a thorough examination of the implications of G "odel's theorem maintaining that conscious thinking must indeed involve ingredients that cannot adequately be simulated by mere computation.

No prior knowledge of quantum theory on the part of the reader is assumed. This book is intended for the general reader; physicists, computer scientists, philosophers, etc.

Format: Taschenbuch
This book is one of the most exciting of its kind.To me,the best science book I ever read. When talking about human brains it is not longer a matter of Computation or the Quantum Model. It's also a quest of one of our primary needs:the knowledge of our selves.Explained from a scientific point of view.It highlights however in a certain way the spiritual dimension of human beings.Without telling us directly,Penrose introduce on the reader's mind phylosophique and religious issues,as possible links on the explanation of the whole. It's true,we can't conclude(after reading the book)we have a definitive explanation,which has been proved right.However on this book,to my knowledge,it's the first time a scientist establish the link:Our Brains:Consciousness and the Quantum Model! If I compare to others books of its kind,such as Stephen Hawkins and Sir Roger Penrose in Space and Time,1995;Leon Lederman in God Particle,1995,Fred A.Wolf in Taking the Quantum Leap,1982 and Star Wave,1984;and finally the previous book of Penrose:The Emperor's New Mind,1990 I have to conclude on the fact that Penrose,on Shadows of the Mind goes beyond frontiers others could not reach before. And I have to analyze briefly the new aspects Penrose approach in a such visionary way:1)The strong possibility that physics(of particles)could be the basis of the appearance of high intellectual functions in our brains(which is quite opposite to the traditional scientific knowledge of the chemical basis being the cause)2)The strong possibility of the emerge of the highest intellectual function:consciousness into the most complex part of our brains:the neuronal synapses(microtubules)and 3)the possibility certain human brains could react differently from the average,because of a different physical arrangement.Lesen Sie weiter... ›

Format: Taschenbuch
Between the beautifully written prologue and epilogue, this book approaches a range of topics in modern physics in a unique and readable way. Through a continuation of some earlier work, Penrose furthers an argument for brain function and conciousness that many in the artificial intelligence field will not appreciate. He presents his case that the human mind will never be simulated with digital a computer, no matter how complex. But that is not his main focus of this book.
Even more facinating are his calculations which indicate how mathematically unique our existence is under the 2nd law of thermodynamics. To me, it's ultimately ironic that the physical principal which orders our universe and makes intelligent life possible (the 2nd law), is the result of an unimaginably improbable set of initial conditions. Although Penrose never invokes the concept of a creator or supreme being, in my mind, this poses an interesting challenge to those in the scientific community who claim our universe is simply the result of random particle collisions over a long period of time.
If we combine the concepts of similar structures scaling across space and time (tensegrity and fractals), with Penrose's ideas that consciousness may be associated with quantum gravity interactions in microtubules (present in all living cells), perhaps there is far more mystery and beauty to this existence than some would now believe...
This book was satisfying and throught provoking, and I highly recommend it to anyone interested in the mysteries of the very large and the very small.

For years I've been preparing a Protocol about Conscioussness and the quantum Model.I'm Medical Research Doctor. I read many books on these subjects ...Stephen Hawkins,and Sir Roger Penrose... Space and Time1995)..Leon Lederman (God Particle 1994)and many others related to the subject.. I want briefly analize Sir Roger Penrose on Shadows of the mind from the two aspects I found the most fascinatings: 1) the possibility of the physical basis of our brains rather than the chemical ones and 2)the strong possibility our conscioussness emerges on the most complex part of our brain:the neuronal synapsis(microtubules). To me this is revolutionnary on actual medical research field and I think it'll be the future of neurological and quantum physics quest....He's on the right pathway....And moreover this kind of knowledge.. if proved right..(of course up to the point of our material,human limitations)..will lead us to answers to those basics HOW'S that really matters:Our brains..how come consciousness make us human beings and differentiated us from animals. Now if I rejoin Leon Lederman on his search of that particle smaller than neutrinos (God Particle)...that one which could stablish perhaps the direct link on the energy-matter hierarchy....I've to ask myself thinking on Penrose'Proposals: What if is that particle emerging directly from energy....the one which makes the whole difference in our cytoskeletons(neuronal synapsis)? What if both explanations...Penrose and Lederman..explain HOW come we became humans?...
