As with all of the National Audubon Society's field guides, the "National Audubon Society Field Guide to the Rocky Mountain States" is a most worthwhile purchase, perfect as a gift or for your own collection. The guide is durable and very portable, which makes it well suited for use in the outdoors. More importantly, it has excellent content. Despite its small size, the field guide contains a wealth of information. In addition to the usual focus on flora and fauna species, there is information on constellations, parks, ecosystems, and more. While the depth and detail of the information in the various sections is not vast, the breadth of subject matter more than makes up for this; the information presented is ideal for a general field guide. Moreover, the book is beautiful, filled with gorgeous color photographs. Residents of the Rocky Mountain states and non-residents will both love it.

I picked up this book because I had some familiarity with the subject matter having worked in that field of biochemistry in the late '60s. That is probably the main reason I read the whole thing and enjoyed it.
This is very much a scientific biography. It's an interesting story of the evolution a scientific idea (The Chemiosmotic Theory) and how that idea came to be accepted by the scientific community. The originator of the idea, the imaginative, ambitious, passionate Peter Mitchell, had to fight for many years to see his theory finally accepted.
I was disappointed, however, that the book did not paint a fuller picture of Mitchell who had many interests outside of science which are (frustratingly) alluded to - music, architecture, farming, family - but never explored. For example, the authors state that family life was very important to Mitchell but give no examples of how a highly motivated scientist/entrepreneur managed to fit it in. Nor is there any sense of what domestic life was like living in an isolated research institute/manor/farm. In my opinion, if these aspects of his life had been more developed, the book would appeal to a wider audience and the reader would come away with a fuller appreciation of the man.
Technically, it is rather a choppy book. Each chapter is divided into subchapters, which detracts from its cohesiveness. Repetition of some points also gives the sense that the book was pieced together.
However, I did read the whole thing and found it an interesting study of how 20th century science works - or works imperfectly.

Published in England. Nicely done. Lots of illustrations. Text is very interesting. The only problem is: it is too short. You can read it completely in under 10 minutes. They should have included more kings and queens and more detail on the ones they did include. Its billed as being a children's book, but the names of some of the kings and queens were difficult for me and I have a master's degree.
