I highly recommend it! After we finish this we'll probably introduce our child to Coldren's book on semiconductor lasers!
Seriously, leaving aside my mockery of the inaccurate reading level rating, it is a decent book. I'd agree that it can be dry and focused on equations more than physics at times, but it offers a very balanced selection of topics, and clearer explanations than many physics books.
I particularly like the progression from old quantum theory to semiclassical theory to the fully quantized theory. It emphasizes the useful aspects of each theory, in particular the usefulness of the old theory in terms of simplicity and accuracy in many situations. History may not always be the best approach to science, but it works if you emphasize the usefulness of simple models and how they follow from more sophisticated models.
Besides, it's much better than Yariv (but what isn't?).
One major complaint: It deals almost exclusively with atomic systems. Those of us who work with molecules or semiconductors need a second reference book to learn more about transitions into a continuum of states (or at least numerous and closely-spaced states).

But the book goes downhill from there. The author spends too much time criticizing the civil rights leadership while minimizing the continuing impact of institutional racism.While acknowledging the lack of comprehensive social policy planning, this author gives no real clue as to why this absence of planning occured in the past and why it is still taking place now.While this is a passable work, there are much better books on urban underclass issues such as William Julius Wilson's "When Work Disappears"

Stark takes as his subject matter the social consequences of monotheistic religion, claiming that the issue of whether God actually exists is unimportant and undiscoverable. His basic conclusions are two: (1) people gravitate toward religion because it promises them something they want--one might call this a "consumer mentality," although Stark himself doesn't use such a label; and (2) monotheistic religions, insofar as each of them claims to be the exclusive sellers of what people want, necessarily breed intolerance.
The problem is that neither of these claims really stand up as straight as Stark wants them to. Surely, for example, there are many reasons why people accept religious beliefs. Some of them may be as crassly consumerist as Stark maintains, but others aren't. Many people gravitate toward religious belief out of a sheer sense of wonderment, or love, or joy. these motives don't fit nicely into Stark's gameplan, and had he even a passing acquaintance with spiritual autobiographies or the tradition of mystical literature in the three Abrahamic religions, he'd have known this. Moreover, if one questions his claim that the draw of monotheistic religions is primarily giving people what they want, then his claim that the traditions are necessarily intolerant because competing against one another likewise becomes problematic.
Stark, a self-styled agnostic, argues that his agnosticism allows him to look upon the phenomenon of religion objectively. One wonders, however. It's clear that the underlying text throughout *One True God* is the old Enlightenment assumption that religious monotheists are either incredibly irrational or selfish or frightened. And in an enlightened world in which everything is perfectly explicable in terms of social analysis, how can one take such religious worldviews seriously?
A sociologist who offers much more reflective accounts of religion is Peter Berger. Read Stark if you wish, but then turn to Berger.
But the flaws are there, as always. First off, the whole reduction of religious belief and involvement to some sort of abstract "economic man" theory is not only annoying, but more importantly, void of empirical data. Costs, benefits, exchange relations, limited supplies, compensators....please. Give it a rest. Sure, some people may choose gods in the same manner they choose laundry detergent -- but most people are religious because of good old fashion processes of socialization. They believe in God because grandma and grandpa do. They worship Buddha because everyone in their village does. They pray to Jesus because that's what mom said to do. For Stark to cling to this rational choice silliness is bizarre -- and strange, coming from someone supposedly affiliated with the discipline sociology. Oh well. I at least appreciate the alternative way of looking at and theorizing about people, flawed though it is.
Finally -- and this is nit-picky I know, but check out this quote in the introduction (p.5):
"It is entirely impossible for science to discover the existence or nonexistence of Gods."
Hm. Really? What if for "Gods" we substituted other possibilities:
"It is entirely impossible for science to discover the existence or nonexistence of Fairies....
of Thor...
of leprechauns....
of floating purple dragons in outer space..."
Those who assert there is a God out there shoulder the burden of proof. Baring convincing evidence, we must remain skeptical. I don't understand why Stark -- who hates "postmodernism and other opponents of reason" (p.14) -- becomes quite post-modern himself by allowing for the existence of Gods without empirical evidence.

The range and scope of the book is hardly narrow and stilted when it takes in medical, military and social history, psychoanalysis, post-structuralism, and literature and philosophy spanning 2000 years.

For anyone working on mobile robotics these papers are a must. I.e. everyone ought to know these papers, both because they are thought provoking and widely referenced. For anyone with access to a library it might be an overkill to pay for this book. Go to the library and read the papers.
The real disappointment here is the lack of a historical perspective. These papers are all 5-15 years old. They strongly influenced the robotics world when they were published. The examples are interesting, but for REAL everyday robot systems the world is more complex than indicated by Brooks. It would have been interesting to see a final chapter that discussed lessons and limitations of the approach when seen in a historical perspective. Brooks is now building a humanoid system (Cog) and one wonders how many of the behaviour based ideas made it into Cog? Probably not as many as this book might indicate.
If you have a library, use you money on an upto date book! If not, you ought to acquire it for a view of the history.
Still, "Cambrian Intelligence" is both thought-provoking (to those primarily acquainted with "classical" AI approaches), and well worth the price tag -- if only for the convenience factor (vs. rounding up and printing out all the included papers).

This book is ridiculous.
As a leftist, Rodney often takes swipes at the capitalist system and given that he died in 1980 the rapid changes in the east west divide is lost on him. This in no way dilutes the core message, substantiated to a great degree, in the book. The evidence, and the logical manner of presentation, to show that Africa ended up in a lose/lose situation is quite compelling.
He did, in his astounding intellectual style, adduce evidence to seriously challenge some stereotypes about Africans prior to the arrival of the Europeans. From the book it is clear that Africans were engaged in a limited form of international trade with the Arabs; it is shown that there were forms of democratic practices commensurate with the level of development of the societies; it is revealed that African Kings and Chiefs are not the bloodhounds they are portrayed to be in the predominant accounts written by non-Africans.
Reading in between the lines in the book, it can be safely averred that the recurrent instability and wars ravaging the continent of Africa are after shocks of the blatant partition of Africa without giving any consideration to the cultural antecedents of the peoples being welded together. Events in Eastern Europe after the collapse of the iron curtain are pointers to the fact that fusing incompatibles is a recipe for chaos. This should be contrasted from individuals volunteering to form a new union.
Interestingly, Rodney also reveals that the question of reparation should not be treated like a pipedream. This is by way of evidence pointing to some big corporations of this age owing their foundation to profits from the abominable and shameful epoch called the slave trade.

The authors must have been confused or took so much for granted. The problems I found with the book are too many. For example: Code snippets fail, poor steps (making the book a very tidious read.). The steps are embedded in lengthy theories, making them impossible to follow. Focus is lost and references are poor. For example, on page 88, they write "you can find this function [global_service_lib.asp] in the include directory". Wrong because, the global_service_lib.asp resides in the siteroot/service/include directory. These are minute errors that can frustrate many readers in the middle of the night.
Some diligence should be put into books that involve program codes. I generally do not tolerate such errors from programmers. We should be people akin to details!!
I have been all over the island hiking. The book was helpful in so much as mentioning where to hike but the directions were not much help at all.

Oh, and there appears to be both a hardcover and a paperback. I bought the paperback used, and it seems to have matched perfectly with the hardcover. Never even used the CD.

So if you're looking for a handbook to give you a simple tour of the mathematics in the quantum theory of light, this is the book for you. If you're looking for a more comprehensive treatment, look elsewhere. The selection of topics is very limited: too little math for a theorist, and too little physics for the experimentalist.
