5.0 out of 5 stars
Thorough, February 16, 2001
The title of this book is slightly misleading, as it implies it is about chaos, complexity and simplicity.In fact the first half of the book is a guided tour of biology, chemisty and physics. Covering how these great sciences got where they are today, from Newton to Darwin, DNA to the lattice structure of diamonds. The second half then presents a new way to look at science. Rather then delving inside something to find underlying rules, we should view things in context. For example, traditionally the law of gravity is seen as the underlying principle that explains planetary motion. Cohen and Stewart argue that it is just a rule (of thumb?) that fits the facts, and that there is no LAW of gravity. It seems a subtle distinction, but on reading this book it is quite an important one, and it has certainly given me a different view of the world. Very intelligent and always interesting, this book is written for the layman and is always at pains to explains matters thoroughly and use every possible analogy to help get ideas across. This book is worth twice the money for the first half alone - a perfect primer for those interested in science, but who dont want to get technical. Cohen and Stewart are high level experts in their respective fields, and yet they write simply and lucidly, resulting in a desire to read further.

Modern Science 101 - a readable, eye-opening survey course, March 15, 1997
By A Customer
In their preface, Jack Cohen and Ian Stewart describe this book as "a streamlined introduction to the central preoccupations of modern science." The concepts of chaos, complexity, and simplicity are central to the book; they are presented without jargon and with marvelous analogies and examples. Much of the discussion of complexity focuses on life, especially human life and human intelligence. An especially useful concept they introduce is the "brain pun," the human brain's tendency to see similarity (bird wings and bat wings) and infer causality or relationship.
This book is remarkable in how much it teaches the intelligent layperson. For example, frog DNA is more complicated than ours because it incorporates so many instructions to the tadpole on how to mature under a wide range of temperature conditions. Human embryos don't need an instruction book with a huge chapter entitled "Coping with Temperature Changes," because we initially grow in the marvelously temperature-controlled environment of the womb. Did you know that? I didn't.
Speaking of instruction books - Cohen and Stewart clearly show that the instruction book metaphor for DNA is flawed. Only a fraction of human DNA is meaningful; the rest is "junk." (Same for other species - it's life, not just us.) But junk DNA replicates, too. Also, for most species in the real world, a wide variety of gene patterns produce pretty much the same animal. Did you know any of this? I didn't.
This is an ideal book for the intelligent layperson whose taste runs to the "readable but accurate." At 443 pages plus notes in the paperback version, it's plenty long enough for a coast-to-coast flight, with some left over for the next day. Highly recommended; I can't wait to pass it on to friends.

all they want to do is remake science, April 9, 2001
This is a witty and at times brilliant book. The authors argue that the reductionist approach to science, which has flourished over the last 300 years, for a more holistic or contrextual approach. In the reductionist approach, scientists have choped problems into manageable bits - lab experiments or discreet mathematical problems - that eventually they assume will be fit together into a coherent whole. Nature in this view functions as a vast machine they can reduce and separate into its component parts. TO prove their point, the authors embark on a dazzling tour of biology, chemistry and physics. But something is missing say the authors. What we know, they claim, are tiny islands in a sea of ignorance; it is self limiting as the larger questions get neglected. It is the causes of simplicity, they say - the order that suddenly emerges - that researchers should explore. So, they conclude, it is time for a new set of questions. Unfortunately, just when we expect something new, it is here that the book gets a bit vague, with the authors falling back on anecdotes and speculation. They try to coin a new vocabulary ("simplexity" for the old and "complicity" for theirs); offer some diagrams of what they want, including an odd picture of mixing smoke with a unicorn head; and they harp on strange and abrupt conclusions, such as the importance of squid fat to the evolution of the human brain. But they do not offer a coherent new paradigm. An uneven effort, but fun and very funny at times.
