This CD-rom is a good exemple how easy can be Immunology, witha good teaching guide. The interative of Navihedrom and the quality ofthe information display in very nice animations is sensational. Dr. Roitt is a leader in Immnology and his leadership go further with these wonderful CD-rom.

I've read a dozen or so books about the Technique over the past dozen years. I became interested in the ideas behind the Technique after having had lessons with 2 very different Alexander Techers. Both teachers helped me a great deal with a chronic back pain problem I'd had since my twenties (I'm 67 now.) My first teacher was very non-verbal, but his hands-on-guidance was very clear and was able to change my posture quite a bit. My second teacher was far more verbal, and also had very good direction in her hands. She encouraged me to do some reading, starting with "Fitness Without Stress"(my favorite) and then "Body Learning" and most recently the Authorized summaries of Alexander's own four books(most of these you can get from Amazon - but the authorized summaries you have to get by mail from an Alexander Technique Professional Society - you can find out more at the Alexander Technique Bookstore at alexandertechnique.com/books)My sense is that Gray's book is not as clear as the other books's on the Technique I've read, although it does cover the basics.

I cannot recommend this book highly enough. I am a violinist with the Academy of St Martin-in-the-Fields and the Technique itself is an **invaluable** element of my life and work---and I would say this book is the best Alexander book not written by FM Alexander himself (it's also much easier to read than FM's brilliant but *very* Victorian prose). This would be my Desert Island Alexander book!

This book is written in an accessible and practical format. It assumes nothing but at the same time treats the reader as an intelligent participant on the journey to understanding evidence based practice.

It is up to date and I was especially impressed with the web address it gives to ensure the reader is kept abreast of any changes since publication.

It systematically explains the need and use of 'evidence', how to find it (the search advice is comprehensive and includes details such as search terms and the best search engines aswell as web addresses) how to evaluate it and also how to act on it.

All in all this book was great, and I would reccomend it to anyone involved in evidence based healthcare practice as it will guide you through the thorniest problems.

To appreciate the history of technological invention it's important to understand society and the scientific community at the time the inventors lived, as well as the political and industrial forces.

The Telephone Patent Conspiracy of 1876 is a good introduction to understanding science and society at the time Thomas Alva Edison, Alexander Graham Bell and a lot of their contemporary inventors, engineers and scientists changed the world by introducing electric lighting and telecommunicatins to the homes and offices.

The book may appear somewhat biased against Bell and focus mainly on the battle between Bell and Gray. People like Emile Berliner and Edison get only cursory treatment, and Antonio meucci is hardly mentioned. At times the author treats information from newspaper clippings with the same authority as official records. Readers are adviced to check the footnotes.

Still, the book is recommended reading for anyone interested in the history of technology.
