Penrose's Fascinating Summary of Modern Science,
By A Customer
This review is from: The Emperor's New Mind: Concerning Computers, Minds and the Laws of Physics (Hardcover)
Roger Penrose, one of the world's top physicists, summarizes modern science, examining topics including Turing machines, relativity, quantum physics, black holes, etc. At the end, he argues that the human mind can not be simulated by computers or anything algorithmic. The Emperor's New Mind is my favorite book, although I didn't feel that way the first time I read it. It is quite technical, compared to, for instance, A Brief History of Time, which covers some of the same topics. The second time I read the book, I really dedicated a lot of time to understand the material as well as I could, often working out problems with paper and pencil. This was necessary for me to see that his conclusion was related to the rest of the book. While Penrose obviously can not "prove" his belief, he gives a strong, fascinating arguement, and the book has definitely affected my philosophical views concerning consciousness.

Profound but challenging and more complex than it need be,

This review is from: The Emperor's New Mind: Concerning Computers, Minds, and the Laws of Physics (Popular Science) (Paperback)
This is a profound book which, inspired by investigations into the nature of the human mind and of artificial intelligence, takes the reader on a roller-coaster tour of aspects of computer science, maths and physics. It calls for a lot of concentration and is not for the faint-hearted. Explanations of many concepts are at a fairly technical level, full of equations and symbols, and I could not help feeling that at times Penrose could have presented things more simply without losing the thread of the argument.The ordinary reader would - as the author himself suggests - be well-advised not to strive to understand all the technical detail: it is possible to grasp the essence of what is being described without following all the intricacies Penrose goes into. The trouble is that this means skimming through much of the book.

Entertaining and Mathematically Advanced,
By
This review is from: The Emperor's New Mind: Concerning Computers, Minds, and the Laws of Physics (Popular Science) (Paperback)
I found this book stimulating and entertaining in equal measure. It looks at the questions such as -- if we had enough information, we could predict absolutely everything, or not? Is the human mind simply a machine (for example a computer)? Can we actually be transported Star-trek style or not? Are we (including our memories) just a collection of atoms that could be reconstituted?In answering these questions Penrose embarks on a tour of the mathematical concepts and theories that underpin our understanding of the Universe. There seems to be much more maths than is really needed, and there is a lot of theory (The book runs to over 500 pages after all). You will also need advanced A level maths to cope (on the basis that I just coped, and that's the level of maths I reached). Entertaining and enjoyable IF you are interested in Maths. If you are not, stay away.
