The first half of the title of this book may delude the uninitiated reader. The term '"Jahn-Teller effect," taken literally, refers to a special effect inherent in particular molecular systems. Actually, this term implies a new approach to the general problem of correlations between the structure and properties of any molecular polyatomic system, including solids. Just such a new approach, or concept (in some sense, a new outlook or even a new way of thinking), which leads not to one special effect but to a series of different effects and laws, is embodied in the many ( ~ 4000) studies devoted to the investigation and application of the Jahn-Teller effect. The term "vibronic interactions" seems to be most appropriate to the new concept, and this explains the origin of the second half of the title. The primary objective of this book is to present a systematic develop ment of the concept of vibronic interactions and its applications, and to illustrate its possibilities and significance in modern chemistry. In the first three chapters (covering about one-third of the book) the theoretical background of the vibronic concept and Jahn-Teller effect is given. The basic ideas are illustrated fully, although a comprehensive presentation of the theory with all related mathematical deductions is beyond the scope of this book. In the last three chapters the applications of theory to spectro scopy, stereochemistry and crystal chemistry, reactivity, and catalysis, are illustrated by a series of effects and laws.

The festive holiday of Shavuot is best known for its all-night Torah learning. The Jewish Sages teach that staying up all night is more than just a celebration of Torah, it is a tikkun, a spiritual rectification. The 16th-century mystic Rabbi Itzchak Luria, the Arizal, prepared a study guide for the night of Shavuot. This guide is presented here, in both Hebrew and English, together with a selection of penetrating insights and commentaries drawn primarily from the mystical teachings of the Zohar and the Arizal.

Isaak Ilyich Rubin (1886-1937) was a Soviet economist who participated in the Russian Revolution and was a researcher at the Marx-Engels Institute Though his ideas were suppressed by the Soviet Union and he was eventually killed after being accused of Trotskyism, his ideas have since been rehabilitated within modern Marxism. Essays on Marx's Theory of Value (1924) emphasizes the importance of Marx's theory of commodity fetishism within the labor theory of value. It also argues that Marx's mature economic work represented the culmination of his lifetime project to understand how human creative power is shaped by social structures. He also discusses commodity production as a mere theoretical abstraction that only explains one aspect of a developed capitalist economy. The concept of value, as understood by Rubin, cannot exist without the other elements of a full-blown capitalist economy: money, capital, the existence of a proletariat, and so on. This Radical Reprint by Pattern Books is made to be accessible and as close to only manufacturing cost as possible.

The authors utilize social science findings for the first time to analyze practical issues that face both Jew and non-Jew. Eighteen widely-published experts in sociology, anthropology, psychology, political science, economics, history, and philosophy have contributed objective examinations of the problems of anti-Semitism in these collected essays.

This volume is the fruit of nearly fifteen years of discussion-in person and by letter-between world-famous British philosopher Isaiah Berlin (1909-1997) and Dr. Beata Polanowska-Sygulska of the Jagiellonian University in Cracow, Poland. Berlin always felt a special affinity for scholars from Eastern Europe, and the unique chemistry between him and this younger enthusiast for his ideas yielded a remarkable body of material, most of it hitherto unpublished.Divided into four sections, the book begins with a selection from the correspondence between Berlin and Polanowska-Sygulska dating from 1983 to 1997. These letters are published here in their entirety for the first time. The second section comprises two interviews Berlin gave in 1991 for Polish periodicals. Next come edited transcripts of a number of recorded conversations that took place between 1986 and 1995. In one conversation, Berlin tellingly recalls his childhood and youth. In other exchanges, the famous conversationalist is pressed to be more precise about some of his most contested views, particularly his concepts of liberty and value pluralism, and to give his response to criticism of these ideas by a wide range of authors. In one of his last letters to Dr. Polanowska-Sygulska, Berlin stated, "I have never expressed myself so clearly before, I believe."The book concludes with a collection of articles on Berlin's thought by Dr. Polanowska-Sygulska, stemming from her long-standing immersion in his work. Berlin himself thoroughly discussed three of these with the author and approved their publication.Complete with a foreword by Henry Hardy, Berlin's editor and collaborator of thirty years, and now one of his literary trustees, this fascinating collection of letters, conversations, and articles sheds considerable light on Berlin's thinking, clarifying some of the central themes of his philosophy.

Drawing on his work as a chiropractor and psychotherapist Regardie saw the devastating effects that tension and stress had on his patients minds and bodies. He shares his extensive knowledge about the body/mind in this work, and helps the reader to reconnect the body with the mind as he/she learns to relax and harmonize these "two" seeming warring entities."Be yourself!" When you relax you are more nearly yourself than at any other time. You will come to realize what you are and what your innate abilities are.
