This book remains a classic in the of field of dislocation dynamics. This is one of the very few textbooks available that deals with kinetic and dynamics of dislocations in a lucid way. The best thing about the book is its numerous illustrations to put across the concepts. This is extremely helpful in understanding the geometry and interactions these complex beasts, dislocations.

The subject is introduced smoothly, starting from review of elastic behaviour and crystal plasticity in a characteristic, lucid manner. Crystal plasticity is introduced in continuum mechanics approach and no use of dislocation concept is used till then. One chapter is devoted exclusively for the geometry of dislocation. The emphasis is on conveying the concepts and there are no complicated derivations for all the special cases. That makes it all the more better. Next few chapters are devoted to the kinematics and dynamics of dislocations, wherein the attention is divided between the dynamics of single dislocation and evolution of collection of dislocation. Being a leading figure in this subject, most of the results in these chapters are Author's own - so he is able present it very clearly. Eventhough first edition of this book came out (1966??) it is still as resourceful as a book published this year.

This field guide to mineral deposits is one of the best I have used. It is easy to use and it provides clear and easy identification of minerals. With over 500 color photos, the book is arranged by color streak and includes the degree of hardness, density, streak description, color, chemical formula, cleavage, crystal form, tenacity and crystal formation. Other features include a list of similar minerals and where the mineral occurs, i.e. in pegmatites. The author also gives advice on where to find minerals and the kind of equipment needed to retrieve them. Also useful is the information on how to organize a collection. The paperback format lends itself to tossing the book into a backpack for easy reference when mineral "hunting" in the field. This is a "must have" for any adventurer's personal library.

This book is very good book for me. I like O. Kahn

This is the only book in my son's collection that he allows me to read each word on every page. The pages are illustrated with bright colors and cleverly drawn characters, the text rhymes and it offers a quasi-question and answer format. I read the questions, "Mommy may I..." and my son gleefully answers, "No! No! No!" or "Yes! Yes! Yes!" when it's time to answer. The questions presented in the book center around events that happen in or around your home (playing with the fish, helping bake, crossing the street alone, playing outside, etc.) and Mommy's answers clearly explain why the child may or may not do as requested. This is a delightful book with a subtle attempt to keep your child safe.

This great book is so sweet. The rhymning is perfect in this story of a little girl's day. The pictures are very cute and colorful. I love reading this to my one year old and my three year old almost has it memorized. I buy it for gifts too.

They say this book is out of print. How sad. I just bought this book and found that it was wonderful reading. All of our every day lives and our experiences are in this book. A great mystery to be solved with the help of an older person. It shows great strengths of all the people in this story who have over come or worked out their own personal problems to bring joy to others.

This book should be bought back for those who love to read books. Memories are made to share and bring joy to others. Margot Dalton is an excellent writer.

The book is easy to read and understand and provides very interesting information for those who are interested in wicca. The book itself is NOT about witchcraft or wicca, but I found it most useful background material, putting matters into a broader perspective. I liked the whole book, except for the last chapter, which is a step too far and not substanciated with facts or convincing arguments.

I found that The Mystical Crystal is a useful guide on crystal therapy techniques. It changed my way of approaching to illnesses and emotional unbalances, through a more assertive and "light" options to cope with the needs of mind and body. I am transcribing bellow the note of the his renowned publisher on metaphysical matters, which is found on the back cover of the book.

"Awareness of interest in the therapeutic properties of crystals have grown enormously in the last few years, as users have discovered the wide range of their beneficial effects.

In The Mystical Crystal, Geoffrey Keite sets out, in sample language, the many applications of crystal therapy, healing and techniques.

From his experience as founder of The Crystal Research Foundation, and director of Crystal 2000, he is able to explain electro crystal therapy, and to detail healing methods, massage and relaxation. Of particular interest are the origins of crystal therapy and its applications to yoga and chakras (personal energy centers).

With none of the obscurity which so often accompanies works on crystal healing, this book will be of immediate interest and benefit to New Age discoverers, and all concerned with balanced natural therapy and alternative techniques for a healthy self. It contains a wealth of experience and advice, based upon the author's long involvement with crystal therapy and refined into direct application."

"It is better to foresee, even without certainty, than not to foresee at all", writes Linus Pauling in the preface of this book, which has become a sort of bible for chemists.When I first read this book, I thought that it was unnecessarily detailed.But then, as I patiently went through the chapters, I realised that Pauling has truly "foreseen with certainty" in his career and discoveries, which is slowly but surely revealed in this book.I would recommend this book to anyone who is interested in how a few simple scientific ideas lead to the explanation of literally hundreds of phenomena.In this book, the two times Nobel Prize winner has beautifully demonstrated how his classic 'Valence Bond Theory' can be applied to explain the bewildering array of atoms, molecules and crystals around us.In each chapter, the author introduces certain classic principles like resonance, electronegativity,partial ionic character of bonds, partial double bond character, and hybridization.These concepts are today the cornerstone of the description of thousands of simple molecules. It should be noted that the valence bond approach has its drawbacks, which Pauling does not discuss.It is also true that the Molecular Orbital Theory has replaced his theory in making quantitative calculations.However, Pauling's masterly style of writing and the insights which almost each and every page of this book give the reader, are unparalleled.Even though the book would perhaps not prove useful as a modern chemistry book, I think it should be read by each and every chemist and chemistry student as the ultimate example of simplicity,variety and beauty.It is one of the finest examples of how one extraordinary scientist tries to explain diverse chemical phenomena with a few simple ideas.

As a Psychologist, over the years, I have strongly recommended the reading of the original edition of this book, which has helped people (yes, men as well as women) to improve their lives and relationships by teaching them how to speak up in a strong, positive, effective way. Looking to purchase another out-of-print copy, I was very excited to see that a new edition has finally come out! I intend to buy several, and give them to people I care about.
