Editorial Reviews

From Publishers Weekly

In this sweeping synthesis, Nobel Prize-winning physicist Gell-Mann ponders the universe's mix of simplicity and complexity, regularity and randomness, as he ranges from quarks (the fundamental subatomic particles which he discovered) to complex adaptive systems like bacteria developing resistance to antibiotics, mobile robots, jaguars, and people interacting with and learning from their environment. Along with often technical chapters on information theory, time, biological evolution and the workings of the subatomic zoo of particles, Gell-Mann devotes special attention to superstring theory, the first viable candidate in physicists' search for a grand unified theory encompassing all the elementary particles and forces. Stressing the urgent need to control population and to preserve biological and cultural diversity, he advocates a multidisciplinary research agenda geared toward a sustainable future for the human race and the biosphere. $50,000 ad/promo; author tour.

From Library Journal

Gell-Mann, a Nobel Prize-winning theoretical physicist and a pioneer in the science of complexity, here examines that important concept, focusing on complex adaptive systems. Such systems are capable of learning and are able to adapt or evolve successfully. The intricate processes used by a child to learn a language, for example, constitute a complex adaptive system, as do the processes used by bacteria to develop resistance to drugs. These systems provide a context or framework for a stimulating discussion of quantum mechanics and the unified theory. Gell-Mann also explores topics such as natural selection, species diversity, and the evolution of human culture in relation to complex adaptive systems. While the topics are technical in nature, Gell-Mann's presentation is clear and will be readily understood by scholars and informed lay readers. Recommended for academic and larger public libraries.

5.0 out of 5 stars A little bit of everything, June 15, 1999

By	Duwayne Anderson (Saint Helens, Oregon) - See all my reviews (REAL NAME)

How do you file a book like "The Quark and the Jaguar?" I could file it with books discussing quantum physics. That would certainly be appropriate. Then, again, I could file it with books on evolution. That would be equally appropriate. But then I might decide to file it in the section on public policy toward the environment, and environmental protection. Certainly, that is an appropriate place for this book. But wait. It also belongs in the section dealing with artificial intelligence and complex adaptive systems. So, where would you put it? I'm still not sure.

Murray Gell-Mann's "The Quark and the Jaguar" takes us on a whirlwind tour from the "simple" construct of quantum physics to the complex adaptive system in a coat of spots moving stealthily through the forest in search of game. Through all this, Gell-Mann ties the entire tapestry into the unifying concepts of complex adaptive systems leaving the reader in awe at the wonder and complexity that arises from the natural evolutionary processes governing the universe in which we live.

The book is organized in four parts. The first is a general-purpose section that discusses everything from information theory to the scientific method and the power of scientific theories. It's always a pleasure to read a description of science and the scientific method from a leading scientist such as Gell-Mann. The sections dealing with falsifiability, selection pressure on the scientific enterprise, unifying characteristics of scientific theories, and the power of theory give a clear and illuminating explanation of the essence of science.

The second part of the book deals with quantum physics. Here you will find Gell-Mann's own story about the (theoretical) discovery of the quark and how it fits into the standard model. Gell-Mann's discussion about the standard model is among the clearest I've seen for the general reader. I found his explanation of all the so-called quantum paradoxes especially well done. From the standard model Gell-Mann explains some of the ideas within superstring theory and the hope that this may provide the unification of physics that has been anticipated for so long.

I always hesitate to differ with anyone of Gell-Mann's stature. Especially in public. It invariably leads to embarrassment. Still, I'm just as loath to read a book and find myself in complete agreement with all its points. On the subject of complexity I found myself out of sorts with the trend followed by Gell-Mann. He begins by describing complexity as algorithmic complexity. This is essentially the length of the shortest binary code that can describe the phenomena. Gell-Mann then points out some rather obvious deficiencies with this definition. For example, it is a maximum for a completely random string of bits, yet we don't typically associate complexity with randomness. From there Gell-Mann takes us to something he calls effective complexity. Yet Gell-Mann laments that this still seems inadequate because it would use the genomes of living things to assess their effective complexity, yet we know (or do we?) that humans are far more complex than apes, even though we share well over 90% of our genetic code.

This apparent desire leads eventually to something Gell-Mann calls "potential complexity." Now, I cannot argue specifically against these definitions. They seem perfectly intuitive and obvious. Still, I cannot shake the feeling that I'm seeing the same process that led scientists in the 19'Th century to define characteristics for the human skull that led to conclusions that whites were more intelligent than blacks. The entire scheme was ultimately based on subconsciously working toward a desired conclusion by manipulating definitions.

Are we more complex than apes? I'm not so sure. Especially when one considers the next effect of humanity on the earth. True, for what it's worth we have an extensive and (is it really?) complex culture. Then again, we are the cause of the greatest mass extinction since the K/T boundary. If you add it all up, I wonder if we really are responsible for more complexity than random destruction.

Sections three and four differ fundamentally from the first two parts. The first two parts deal with what Gell-Mann would call simple systems. Things like quantum physics and the general theory of relativity. The really complicated stuff is in biology. Part three deals with that and more, including general discussions about how complex adaptive systems learn. I found the part on creative learning especially interesting. This section purports to explain how to enhance one's ability to think creatively. The section is only ˝ page long. Interestingly, creative thinking correlates with what often appears to be random thought processes. I couldn't help wondering about the conclusions regarding algebraic complexity and randomness.

The book ends with section four, which is really Gell-Mann's views on various social issues, particularly those associated with the environment. I could not help wishing, as I read these last few pages, that our species could not have a few more men like Gell-Mann. What a difference it would make if his level of intellect, honesty, compassion, and logic could be brought to focus on more issues. It left me with a renewed determination to follow his lead in doing more to preserve biodiversity on earth for the earth, and for future generations.

If you find wonder in the world, and excitement in a journey of discovery, then I recommend Gell-Mann's book wholeheartedly.

5.0 out of 5 stars Anyone who enjoys thinking should read (and like) this book!, February 22, 2003

By	Oliver Harris (London) - See all my reviews

Gell-mann is, quite simply, an expert in more fields than most people have a passing interest in. Added to this is a lucid, entertaining writing style, and the ability to knit together seemingly disparate concepts from the fields of physics, cosmology, genetics, information theory, evolution, behavioural psychology, sociology...you name it.

It seems a few people have been criticising Gell-mann for overextending himself, boasting about his own achievements or simply writing a dislocated, jumbled book. My advice to these people is to 'look for the patterns behind the apparent randomness', as Gell-mann might have put it (because they are there, all right), give him his due for his own (considerable) contributions to physics and admire his courage in even attempting to connect so many ideas, let alone succeeding as well as does.

I loved this book, and I think anyone interested in just about any aspect of science ought to like it too.

5.0 out of 5 stars Save your money, and buy this book!, November 1, 2001

By	Hrvoje (Zagreb, Croatia) - See all my reviews

Saving money by buying this book? How can that be? The answer is very simple.

1) For instance, you want to buy a book about thought experiment involving Schrödinger cat, because you are interested how is it possible that cat can be simultaneously both, live and dead. Well, quantum mechanics doesn't imply that cat is live and dead at the same time, so there is no such a problem.

2) Say, you want to buy a book about parallel universes which suppose to emerge from strange quantum mechanical laws. Don't, because those parallel universes doesn't emerge from quantum mechanics (or from any other known physical law!)

3) Likewise, don't buy books which wants to 'explain' spooky affects of one photon on the other in the distance. That is not what happening after all.

4) Also, some books covers the subject about how biological evolution violate the second law of thermo-dynamics (because in biological evolution order tend to increase with the passage of time). Truth is that this is not truth.

All these, and many other questions Gell-Mann clearly explain in 'Quark and the Jaguar', so don't waste your time and money on those books.

You may ask your self: But, maybe Gell-Mann is wrong? Maybe he is, but it is extremely unlikely. He is the greatest living authority on quantum mechanics you can find around, so it is very wise to take seriously what he wants to tell us. Gell-Mann is, by all means, a far away from popular speculation and misunderstandings. His goal is not to take your money by writing what most people want to hear - a kind of misticism in science.

'Quark and the Jaguar' covers really wide range of subjects, which is not very surprising considering his brilliant mind. If you want to open up your mind this is the book for you. After reading it, you can start studying subjects you are especially interested for. 'Quark and the Jaguar' is must for any intelligent individual.
