rating : 2.5 : great stuff
review : 14 January 2001

A brilliant and vastly irritating book. Brilliant because it covers a wide range of fascinating subjects, with many intriguing new insights. Irritating because it never seems to go into sufficient depth about any of them.

The book covers two main topics, and tries to integrate them. The section on quantum mechanics and fundamental particles -- Gell-Mann's original background -- has some fascinating stuff on the modern "many alternative histories" interpretation of QM, coarse-graining and entropy, and the link to the quasi-classical domain. All gripping stuff, and worth a whole (popular) book of their own. Then the section on Complex Adaptive Systems -- based on Gell-Mann's more recent work at the Santa Fe Institute, has lots of equally fascinating insights into evolution, information, complexity, chaos, self-organisation, adaptation, and so on. But again, tons of interesting ideas are each compressed into a sentence or two. The text is split, under headings, into half-page or one-page fragments, each of which could usefully be expanded almost to chapter length in order to discuss fully the points Gell-Mann mentions in passing.

The Afterword, announced as a kind of "executive summary" (so why wasn't it at the beginning?), compresses further the entire book into nine breathlessly dense pages. However, I felt that the entire book acted as an executive summary to the book(s) I really want to read. Gell-Mann admits that the book "reaches into a large number of areas it cannot explore thoroughly or in depth" -- indeed, many of those areas are still subjects of active research -- and that its purpose is "to stimulate thought and discussion" -- it certainly does that, but a Further Reading section would have been a welcome addition.

in general ... the behaviour of highly complex nonlinear systems may exhibit simplicity, but simplicity that is typically emergent and not obvious at the outset
