This book is the proceedings of a Symposium entitled "The Physics of Solid-Solution Strengthening in Alloys" which was held at McCormick Place, Chicago, on October 2, 1973, in association with a joint meeting of the American Society for Metals (ASM) and The Metallurgical Society (TMS) of the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME). The symposium, which was initiated and organized by the editors of this volume, was sponsored by the Committee on Alloy Phases, Institute of Metals Division, TMS, AIME, and the Flow and Fracture Section of the Materials Science Division, ASM. The discipline of Alloy Design has been very active in recent years, during which considerable stress has been placed on the roles of crystallography and microstructure in the rationalization and prediction of properties. Underestimated as a component of alloy design, however, has been the importance of physical property studies, even though physical property measurements have tradi tionally been employed to augment direct or x-ray observations in the determination of phase equilibrium (and, indeed, metastable equilibrium) boundaries."

The Bahir is one of the primary sources of the Kabbalah. It first appeared in the late twelfth century and was published in 1651 in Amsterdam. This is a translation of this edition. The 1651 edition differs somewhat to other versions, as it still includes many principles of the original Kabbalah, which later Kabbalists changed or rejected. Contemporary Kabbalists consider the Bahir to be a mystical work, whereas the ancient Kabbalists considered it to be a cosmological work. The Bahir is full of rich symbolism which conveys a profound cosmology. Although the symbolism of the Bahir is generally simple in its form, few have been able to penetrate its mysteries. Consequently, many Kabbalists have described the Bahir as one of the most obscure works of the Kabbalah. But the Bahir is not obscure; it is clear and bright. It clearly describes, through various symbolic forms, the creation and constitution of the universe, besides many other important mysteries. The Bahir is a spring of wisdom waiting for those that thirst for true wisdom to come and drink.

The Sefer Yetzirah is the fundamental source of the Kabbalah. Numerous editions of the text exist. Each describes the creation of the universe in different ways. The differences relate to the different Kabbalistic Schools that used the text. No edition contains the full knowledge of the different Schools; thus, it is necessary to study the different versions of the Sefer Yetzirah to gain a fuller understanding of the Kabbalah.
