A must-read book for understanding this vibrant and influential modern Jewish movement Hasidism originated in southeastern Poland, in mystical circles centered on the figure of Israel Ba’al Shem Tov, but it was only after his death in 1760 that a movement began to spread. Today, Hasidism is witnessing a remarkable renaissance around the world. This book provides the first comprehensive history of the pietistic movement that shaped modern Judaism. Written by an international team of scholars, its unique blend of intellectual, religious, and social history demonstrates that, far from being a throwback to the Middle Ages, Hasidism is a product of modernity that forged its identity as a radical alternative to the secular world.
David Shahar (1926–1997), author of the seven-novel sequence The Palace of Shattered Vessels, occupies an ambiguous position in the Israeli literary canon. Often compared to Proust, Shahar produced a body of work that offers a fascinating poetic and ideological alternative to the dominant models of Amos Oz and A. B. Yehoshua. This book, the first full-length study of this fascinating author, takes a fresh look at the uniqueness of his literary achievement in both poetic and ideological terms. In addition to situating Shahar within the European literary tradition, the book reads Shahar's representation of Jerusalem in his multi-volume novel as a "heterotopia"—an actual space where society's unconscious (what does not fit on its ideological map) is materially present—and argues for the relevance of Shahar's work to the critical discussion of the Arab question in Israeli culture.
Spinors are used extensively in physics. It is widely accepted that they are more fundamental than tensors, and the easy way to see this is through the results obtained in general relativity theory by using spinors -- results that could not have been obtained by using tensor methods only. The foundation of the concept of spinors is groups; spinors appear as representations of groups. This textbook expounds the relationship between spinors and representations of groups. As is well known, spinors and representations are both widely used in the theory of elementary particles. The authors present the origin of spinors from representation theory, but nevertheless apply the theory of spinors to general relativity theory, and part of the book is devoted to curved space-time applications. Based on lectures given at Ben Gurion University, this textbook is intended for advanced undergraduate and graduate students in physics and mathematics, as well as being a reference for researchers.
Moshe Rosman cogently and critically presents the considerations that must be brought to bear on the writing of Jewish history in the light of post-modernist thinking.
This book contains the general description of the mathematical pendulum subject to constant torque, periodic and random forces. The latter appear in additive and multiplicative form with their possible correlation. For the underdamped pendulum driven by periodic forces, a new phenomenon — deterministic chaos — comes into play, and the common action of this chaos and the influence of noise are taken into account. The inverted position of the pendulum can be stabilized either by periodic or random oscillations of the suspension axis or by inserting a spring into a rigid rod, or by their combination. The pendulum is one of the simplest nonlinear models, which has many applications in physics, chemistry, biology, medicine, communications, economics and sociology. A wide group of researchers working in these fields, along with students and teachers, will benefit from this book.
This book describes Carmeli's cosmological general and special relativity theory, along with Einstein's general and special relativity. These theories are discussed in the context of Moshe Carmeli's original research, in which velocity is introduced as an additional independent dimension. Four- and five-dimensional spaces are considered, and the five-dimensional braneworld theory is presented. The Tully-Fisher law is obtained directly from the theory, and thus it is found that there is no necessity to assume the existence of dark matter in the halo of galaxies, nor in galaxy clusters.The book gives the derivation of the Lorentz transformation, which is used in both Einstein's special relativity and Carmeli's cosmological special relativity theory. The text also provides the mathematical theory of curved spacetime geometry, which is necessary to describe both Einstein's general relativity and Carmeli's cosmological general relativity. A comparison between the dynamical and kinematic aspects of the expansion of the universe is made. Comparison is also made between the Friedmann-Robertson-Walker theory and the Carmeli theory. And neither is it necessary to assume the existence of dark matter to correctly describe the expansion of the cosmos.
Focusing on Oriental Jews and their relations with their Arab neighbors in Mandatory Palestine, this book analyzes the meaning of the hybrid Arab-Jewish identity that existed among Oriental Jews, and discusses their unique role as political, social, and cultural mediators between Jews and Arabs. Integrating Mandatory Palestine and its inhabitants into the contemporary Semitic-Levantine surroundings, Oriental Neighbors illuminates broad areas of cooperation and coexistence, which coincided with conflict and friction, between Oriental and Sephardi Jews and their Arab neighbors. The book brings the Oriental Jewish community to the fore, examines its role in the Zionist nation-building process, and studies its diverse and complex links with the Arab community in Palestine.
Assuming only basic algebra and Galois theory, the book develops the method of "algebraic patching" to realize finite groups and, more generally, to solve finite split embedding problems over fields. The method succeeds over rational function fields of one variable over "ample fields". Among others, it leads to the solution of two central results in "Field Arithmetic": (a) The absolute Galois group of a countable Hilbertian pac field is free on countably many generators; (b) The absolute Galois group of a function field of one variable over an algebraically closed field $C$ is free of rank equal to the cardinality of $C$.
The third volume of the former Israeli prime minister’s journals from the nation’s early years. My Struggle for Peace is a remarkable political document offering insights into the complex workings of the young Israeli political system, set against the backdrop of the disintegration of the country’s fragile armistice with the Arab states. Replete with Moshe Sharett’s candid comments on Israel’s first-generation leaders and world statesmen of the day, the diary also tells the dramatic human story of a political career cut short—the removal of an unusually sensitive, dedicated, and talented public servant. My Struggle for Peace is, above all, an intimate record of the decline of Sharett’s moderate approach and the rise of more “activist-militant” trends in Israeli society, culminating in the Suez/Sinai war of 1956. The diary challenges the popular narrative that Israel’s confrontation with its neighbors was unavoidable by offering daily evidence of Sharett’s statesmanship, moderation, diplomacy, and concern for Israel’s place in international affairs. This is the third volume in the 3-volume English abridgement of Sharett’s Yoman Ishi [Personal diary] (Ma’ariv, 1978) maintains the integrity, flavor, and impact of the 8-volume Hebrew original and includes additional documentary material that was not accessible at the time. The volumes are also available to purchase as a set or individually. “The editors . . . vastly improved on the Hebrew version by adding Sharett’s speeches, reports, cabinet minutes, and other sources to the text. . . . These additions makes this work so important and welcome by all who aspire to understand the foreign and defense policies of Israel in its first decade.” —Israel Studies Review
A theoretical framework for analyzing the complex relationship of education, growth, and income distribution. The dominant role played by the state in the financing, regulation, and provision of primary and secondary education reflects the widely-held belief that education is necessary for personal and societal well-being. The economic organization of education depends on political as well as market mechanisms to resolve issues that arise because of contrasting views on such matters as income inequality, social mobility, and diversity. This book provides the theoretical framework necessary for understanding the political economy of education—the complex relationship of education, economic growth, and income distribution—and for formulating effective policies to improve the financing and provision of education. The relatively simple models developed illustrate the use of analytical tools for understanding central policy issues. After offering a historical overview of the development of public education and a review of current econometric evidence on education, growth, and income distribution, the authors lay the theoretical groundwork for the main body of analysis. First they develop a basic static model of how political decisions determine education spending; then they extend this model dynamically. Applying this framework to a comparison of education financing under different regimes, the authors explore fiscal decentralization; individual choice between public and private schooling, including the use of education vouchers to combine public financing of education with private provision; and the social dimension of education—its role in state-building, the traditional "melting pot" that promotes cohesion in a culturally diverse society.
This is the only book on the subject of group theory and Einstein's theory of gravitation. It contains an extensive discussion on general relativity from the viewpoint of group theory and gauge fields. It also puts together in one volume many scattered, original works, on the use of group theory in general relativity theory.There are twelve chapters in the book. The first six are devoted to rotation and Lorentz groups, and their representations. They include the spinor representation as well as the infinite-dimensional representations. The other six chapters deal with the application of groups -particularly the Lorentz and the SL(2,C) groups — to the theory of general relativity. Each chapter is concluded with a set of problems.The topics covered range from the fundamentals of general relativity theory, its formulation as an SL(2,C) gauge theory, to exact solutions of the Einstein gravitational field equations. The important Bondi-Metzner-Sachs group, and its representations, conclude the book. The entire book is self-contained in both group theory and general relativity theory, and no prior knowledge of either is assumed.The subject of this book constitutes a relevant link between field theoreticians and general relativity theoreticians, who usually work rather independently of each other. The treatise is highly topical and of real interest to theoretical physicists, general relativists and applied mathematicians. It is invaluable to graduate students and research workers in quantum field theory, general relativity and elementary particle theory.
This book contains comprehensive descriptions of stochastic processes described by underdamped and overdamped oscillator equations with additive and multiplicative random forcing. The latter is associated with random frequency or random damping. The coverage includes descriptions of various new phenomena discovered in the last hundred years since the explanation of Brownian motion by Einstein, Smoluchovski and Langevin, such as the shift of stable points, noise-enhanced stability, stochastic resonance, resonant activation, and stabilization of metastable states. In addition to many applications in physics, chemistry, biology, medicine, economics and sociology, these discoveries have clarified the deep relationship between determinism and stochasticity, which turns out to be complimentary rather than contradictory, with noise playing both constructive and destructive roles.
Stochastic descriptions of a harmonic oscillator can be obtained by adding additive noise, or/and three types of multiplicative noise: random frequency, random damping and random mass. The first three types of noise were intensively studied in many published articles. In this book the fourth case, that of random mass, is considered in the context of the harmonic oscillator and its immediate nonlinear generalization — the pendulum. To our knowledge it is the first book fully dedicated to this problem.Two interrelated methods, the Langevin equation and the Fokker-Planck equations, as well as the Lyapunov stability method are used for the mathematical analysis. After a short introduction, the two main parts of the book describe the different properties of the random harmonic oscillator and the random pendulum with random masses. As an example, the stochastic resonance is studied, where the noise plays an unusual role, increasing the applied weak periodic signal, and also the vibration resonance in dynamic systems, where the role of noise is played by the second high-frequency periodic signal.First and second averaged moments have been calculated for a system with different types of additive and multiplicative noises, which define the stability of a system. The calculations have been extended to two multiplicative noises and to quadratic noise. This book is useful for students and scientists working in different fields of statistical physics.
The properties of the harmonic oscillator with random frequency or/and random damping formed the content of the first edition. The second edition includes hundreds of publications on this subject since 2005. The noisy oscillator continues to be the subject of intensive studies in physics, chemistry, biology, and social sciences.The new and the latest type of a stochastic oscillator has also been considered, namely, an oscillator with random mass. Such model describes, among other phenomena, Brownian motion with adhesion, where the molecules of the surrounding medium not only randomly collide, but also stick to the Brownian particle for some (random) time, thereby changing its mass. This edition contains two new chapters, eight new sections and an expanded bibliography. A wide group of researchers, students and teachers will benefit from this book.

Moshe Shokeid narrates his experiences as a member of AD KAN (NO MORE), a protest movement of Israeli academics at Tel Aviv University, who fought against the Israeli occupation of Palestinian territories, founded during the first Palestinian Intifada (1987-1993). However, since the assassination of Prime Minister Rabin and the later obliteration of the Oslo accord, public manifestations of dissent on Israeli campuses have been remarkably mute. This chronicle of AD KAN is explored in view of the ongoing theoretical discourse on the role of the intellectual in society and is compared with other account of academic involvement in different countries during periods of acute political conflict.
The author analyzes ever reference to the Land of Israel in the 54 Torah portions read on Shabbat and the Jewish Holidays. He shows how living in the Holy Land is a fulfillment of the deep yearnings of millennia of Jews who come to Israel to perform all of God's commandments, especially those that depend on the Land.
This book provides a thorough and detailed examination of Israeli institutions and how they function. It explains the decline in effectiveness of the government and the spread of cultural malaise in the Israel of the eighties. Horowitz and Lissak trace the integrative and disintegrative trends in Israel and show how a society that had laid the foundations for a cohesive Jewish nation-state became increasingly vulnerable to centrifugal forces. The book not only reflects a broad and comprehensive approach, but also focuses on themes that cut across institutional structures, such as the weakening of social and political cohesion in an overburdened polity.
Life makes warriors of us all. To emerge the victors, we must arm ourselves with the most potent of weapons. That weapon is prayer." --Rebbe Nachman of Breslov The "gentle weapon" of prayer can ease the soul and strengthen the heart, while bringing us closer to God and to a deeper understanding of ourselves. Two hundred years after he lived, the warm insights and generous wisdom of Rebbe Nachman of Breslov (1772-1810) continue to be a source of comfort for those in search of an uplifting perspective on life. "When you pray, hold nothing back from God. Pour out your heart with honest openness, as if you were speaking to your very best friend." --Rebbe Nachman of Breslov (1772-1810) A "little treasure" of prayers that will open your heart and soul and give voice to your deepest yearnings. Using the startling wisdom of Rebbe Nachman of Breslov, written two hundred years ago, The Gentle Weapon will help you talk with God and enable you to hear your own voice as well. This spiritual gem makes a loving gift to friends, family or to ourselves when words of comfort are what's needed the most.
Until recently, issues surrounding ethnic-linked inequality, whether between Jews and Arabs or between Jewish ethnic groups, have dominated research on stratification in Israel to the exclusion of other dimensions. Rapidly growing inequality in Israeli society, and its intergenerational persistence, however, have generated several new trends in research. The chapters included in this volume represent the range and depth of recent developments in the study of social stratification, mobility, and inequality. Although they address a variety of issues, they have in common a focus on the institutional mechanisms that govern the allocation of rewards.
The book brings together the essays on Second Temple Judaism by Moshe Weinfeld, one of the leading figures in comparative literature and the history of religion in ancient Near Eastern studies. This integrated collection centers on the religious debates within Second Temple Judaism between the sectarian Qumran community and the Pharisees. It examines topics such as liturgy, law, theology and ideology; issues that established Jewish religious forms for normative, Rabbinic Judaism. It also sets these debates in the broader context of texts and ideas from the Bible and ancient Near East texts on one hand and the New Testament and Rabbinic Judaism on the other. The book comprises four sections. The first, 'Prayer and Worship' analyzes constitutive ideas reflected in the definitive prayers of Qumran and Pharisaic liturgy. The second, 'The Qumran Scrolls' engages various legal and hermeneutic issues in the literature of the Qumran sect. Section three, 'Theology and Ideology' treats a group of foundational Jewish concepts from the historical point of view. The final section 'The New Testament' brings several basic concepts and conceptions of Judaism into New Testament context. This is volume 54 in the Library of Second Temple Studies series (formerly the Journal for the Study of the Pseudepigrapha Supplement series).
The last in a series of three volumes edited by Marc Lee Raphael surveying some of the major rabbinic and lay personalities who have shaped Judaism in America for the past two centuries, this work focuses on Orthodox Judaism. Along with a basic description of the achievements of some of the most notable leaders, a bibliography of their writings and sources for further study is included as well as an essay on Orthodox rabbinic organizations and a survey of American Orthodox periodicals. Of interest to scholars, students, and lay persons alike, this volume will inform readers about the earliest communities of Jews who settled in America as they developed the institutions of Orthodox Jewish life and set a public standard of compliance with Jewish law. These early American Jews followed a Spanish-Dutch version of Sephardic customs and rites. Their synagogues used traditional prayer books, promoted the celebration of Jewish holidays, established mikvahs, acquired Passover provisions, and arranged for cemetery land and burial services. While many of these Sephardic immigrants did not maintain halakha in their daily regimen as did their European counterparts, they set a public standard of compliance with Jewish law, thus honoring Jewish tradition. Further immigration of thousands of Jews from Western and Central Europe in the middle of the 19th century brought a world of traditional piety and extensive Jewish learning to America, exemplified by Rabbi Abraham Rice, who served in Baltimore, and Yissachar Dov (Bernard) Illowy, who served communities from Philadelphia to New Orleans. Such men marked the beginning of a learned and scholarly rabbinate in America. This volume provides valuable biographical insights regarding some of the most notable religious leaders in American Orthodoxy.
A comprehensive and accessible account of the life and thought of Judaism's most celebrated philosopher Maimonides was the greatest Jewish philosopher and legal scholar of the medieval period, a towering figure who has had a profound and lasting influence on Jewish law, philosophy, and religious consciousness. This book provides a comprehensive and accessible introduction to his life and work, revealing how his philosophical sensibility and outlook informed his interpretation of Jewish tradition. Moshe Halbertal vividly describes Maimonides's childhood in Muslim Spain, his family's flight to North Africa to escape persecution, and their eventual resettling in Egypt. He draws on Maimonides's letters and the testimonies of his contemporaries, both Muslims and Jews, to offer new insights into his personality and the circumstances that shaped his thinking. Halbertal then turns to Maimonides's legal and philosophical work, analyzing his three great books—Commentary on the Mishnah, the Mishneh Torah, and the Guide of the Perplexed. He discusses Maimonides's battle against all attempts to personify God, his conviction that God's presence in the world is mediated through the natural order rather than through miracles, and his locating of philosophy and science at the summit of the religious life of Torah. Halbertal examines Maimonides's philosophical positions on fundamental questions such as the nature and limits of religious language, creation and nature, prophecy, providence, the problem of evil, and the meaning of the commandments. A stunning achievement, Maimonides offers an unparalleled look at the life and thought of this important Jewish philosopher, scholar, and theologian.
The theory presented in this book is a combination of Einstein's original special and general relativity, but now the starting point is not the propagation of light but the expansion of the Universe. The traditional Hubble constant H0 (which is not constant) is called in this book the Hubble parameter. Its value at low gravity is denoted by h, and its reciprocal is denoted by τ. Thus τ is the Big Bang time (some authors call it the Hubble-Carmeli constant). This is actually the only constant that appears in this theory, just as c is the only constant that appears in Einstein's theory. There is no cosmological constant but there is a critical mass density. The theory presents general relativity in the space-velocity (of the receding galaxies) which is later on extended to include the time dimension. So far all experimental findings are satisfied by this theory.
Bisk and Dror assert that the 21st Century can be the Jewish Century, that no other people is better prepared to face its challenges. However, to do so, a stress on the Jewish Future must replace a preoccupation with the Jewish Past. They offer a neo-Zionist ideological analysis of modern Jewish life as an alternative to both classical Zionism and post-Zionism. They conceptualize a Jewish Grand Strategy by clearly defining and delineating between ideology, policy, grand strategy, strategy and tactics, with compelling proposals for what such a revised Grand Straegy might entail. They suggest a concept of reinvigorated Israel-Diaspora relations based on this new Grand Strategy and the potential of the Information Technology Revolution. They also offer a conception of Jewish spirituality that could be as appealing to secular as to religious Jews. They reject the concept of a Nation that Dwells Alone. Throughout the ages, Jews have affected and been affected by the world more than any other People they assert. They also reject the view that suffering is the dominant feature of Jewish history as this lachrymose perception cannot inspire needed Jewish ambitions in the young. They stress the needs of the Jewish person and insist that there can be no real significance to the continued existence of the Jewish People unless the real life, concrete needs of the individual are addressed. As former Israeli Ambassador to the United Nations and former Cabinent Minister Gad Yaacobi asserts in his foreword, The book is original, iconoclastic and in some ways revolutionary ... it challenges inherited assumptions and calls for positive action. I believe we have before us a book that must become a reference point for Jewish policy makers as quickly as possible.
Finite model theory,as understoodhere, is an areaof mathematicallogic that has developed in close connection with applications to computer science, in particular the theory of computational complexity and database theory. One of the fundamental insights of mathematical logic is that our understanding of mathematical phenomena is enriched by elevating the languages we use to describe mathematical structures to objects of explicit study. If mathematics is the science of patterns, then the media through which we discern patterns, as well as the structures in which we discern them, command our attention. It isthis aspect oflogicwhichis mostprominentin model theory,“thebranchof mathematical logic which deals with the relation between a formal language and its interpretations”. No wonder, then, that mathematical logic, and ?nite model theory in particular, should ?nd manifold applications in computer science: from specifying programs to querying databases, computer science is rife with phenomena whose understanding requires close attention to the interaction between language and structure. This volume gives a broadoverviewof some central themes of ?nite model theory: expressive power, descriptive complexity, and zero–one laws, together with selected applications to database theory and arti?cial intelligence, es- cially constraint databases and constraint satisfaction problems. The ?nal chapter provides a concise modern introduction to modal logic,which emp- sizes the continuity in spirit and technique with ?nite model theory.
During the last decades, healthcare in the various industrialized countries has been deteriorating steadily. The enormous progress of medicine in the same period could only partly compensate for the loss. This book describes the deterioration of healthcare that increases continually. It analyses its causes and outlines the measures that might prevent or at least slow the change. The deterioration of healthcare, variable in different fields, progressing at different paces in the various industrialized countries, is produced mainly by two types of causes. Minor ones, resulting from lack of knowledge, or by inadequate equipment or procedures, can be corrected by relatively simple means, such as education and technical or procedural improvements. The major causes for the deterioration involve general policy whose effects are the steady decrease in monitoring health care and the change of healthcare into profit-seeking service. The data collected and its analysis is based on over 300 articles in major medical and nursing journals. It has three parts: part 1 deals with individual doctors' errors, part 2 with errors of the medical establishment, and part 3 is devoted to more theoretical a
The revealing memoir of one of Israeli's most respected statesmen. Moshe Arens is one of the last surviving members of the founding generation of Israelis. He is a political insider who has worked with every Israeli prime minister from Menachem Begin to Benjamin Netanyahu, serving in a variety of important positions, including foreign minister and defense minister. He has also enjoyed an exceptionally close life-long relationship with the United States: he attended high school in New York and colleges in Massachusetts and California, married an American, and served as Israel's ambassador to the United States. In this memoir, Arens recounts his early role in the birth of Israel and developing Israel's aerospace industry, followed by a long and distinguished political career that included service at the very top of Israel's government for the better part of three decades. Arens advocated relentlessly throughout his political career for his vision of an Israel strong enough to withstand all challenges in its volatile neighborhood. In Defense of Israel vividly recounts the many battles Arens fought in the political arena, sometimes successfully, sometimes not. The latter included his strong opposition to Prime Minister Ariel Sharon's withdrawal from Gaza and parts of the West Bank—an action that led to the takeover of Gaza by Hamas. Anyone interested in Israel's place within the contemporary Middle East, including Israel's relationship with the United States, will find this memoir informative, even eye-opening, and often provocative.
In Samson Raphael Hirsch's Religious Universalism and the German-Jewish Quest for Emancipation Moshe Miller argues that nineteenth-century German Jews of all persuasions actively sought acceptance within German society and aspired to achieve full emancipation from the many legal strictures on their status as citizens and residents. But, where non-Orthodox Jews sought a large measure of cultural assimilation, Orthodox Jews were content with more delimited acculturation. However, they were no less enthusiastic about achieving emancipation and acceptance in German society. There was one issue, though, which was seen by non-Jewish critics of emancipation as a barrier to granting civic rights to Jews: namely, the alleged tribalism of the Jewish ethic and the supposedly Orthodox notion of Jews as "the Chosen People." These charges could not go unanswered, and in the writings of Rabbi Samson Raphael Hirsch (1808-1888), a leading thinker of the Orthodox camp, they did not. Hirsch stressed the universalism of the Jewish ethic and the humanistic concern for the welfare of all mankind, which he believed was one of the core teachings of Judaism. His colleagues in the German Orthodox rabbinate largely concurred with Hirsch's assessment. This account places Hirsch's views in their historical context and provides a detailed account of his attitude toward non-Jews and the Christianity practiced by the vast majority of nineteenth-century Europeans"--
In Obsessive-Compulsive Disorder and Uncertainty: Struggling with a Shadow of a Doubt, Moshe Marcus and Steven Tuber examine the structural and intrapsychic features of the self as presented within OCD compulsive doubting, and more broadly, within OCD compulsions. Marcus and Tuber further elucidate central object-relational paradigms within OCD doubting and suggest a broader framework that can be used to consider the interplay between both the cognitive as well as the affective components required to make judgments.
Source control is the key to the management of surgical infections. Surgical decision making is based on the marriage of evidence from clinical studies, inferences from biology, and the elusive component of surgical experience; this book combines these three elements. We have recruited an international group of authors who are acknowledged leaders in the field of surgical infectious diseases. We have challenged them to integrate evidence with experience and an understanding of biology so as to create overviews that will help the clinician who must make the difficult decisions. And we have kept them honest by asking a second group of equally eminent commentators to provide supporting or alternative views - in essence, to recreate the kind of dialogue that takes place between clinicians discussing a difficult problem. This is THE manual for the authoritative management of surgical infections!
Pendulum is the simplest nonlinear system, which, however, provides the means for the description of different phenomena in Nature that occur in physics, chemistry, biology, medicine, communications, economics and sociology. The chaotic behavior of pendulum is usually associated with the random force acting on a pendulum (Brownian motion). Another type of chaotic motion (deterministic chaos) occurs in nonlinear systems with only few degrees of freedom. This book presents a comprehensive description of these phenomena going on in underdamped and overdamped pendula subject to additive and multiplicative periodic and random forces. No preliminary knowledge, such as complex mathematical or numerical methods, is required from a reader other than undergraduate courses in mathematical physics. A wide group of researchers, along with students and teachers will, thus, benefit from this definitive book on nonlinear dynamics.
This invaluable book presents gravitation and gauge fields as interrelated topics with a common physical and mathematical foundation, such as gauge theory of gravitation and other fields, giving emphasis to the physicist's point of view.About half of the material is devoted to Einstein's general relativity theory, and the rest to gauge fields that naturally blend well with gravitation, including spinor formulation, classification of SU(2) gauge fields and null-tetrad formulation of the Yang-Mills field in the presence of gravitation.The text includes a useful introduction to the physical foundation of the theory of gravitation. It also provides the mathematical theory of the geometry of curved space-times needed to describe Einstein's general relativity theory.
This book goes farther than any previous work in uncovering the historical Israel ben Eliezer--known as the Ba'al Shem Tov, or the Besht--the eighteenth-century Polish-Jewish mystic who profoundly influenced the shape of modern Judaism. As the progenitor of Hasidism, the Ba'al Shem Tov is one of the key figures in Jewish history; to understand him is to understand an essential element of modern Jewish life and religion. Because evidence about his life is scanty and equivocal, the Besht has long eluded historians and biographers. Much of what is believed about him is based on stories compiled more than a generation after his death, many of which serve to mythologize rather than describe their subject. Rosman's study casts a bright new light on the traditional stories about the Besht, confirming and augmenting some, challenging others. By concentrating on accounts attributable directly to the Besht or to contemporary eyewitnesses, Rosman provides a portrait drawn from life rather than myth. In addition, documents in Polish and Hebrew discovered by Rosman during the research for this book enable him to give the first detailed description of the cultural, social, economic, and political context of the Ba'al Shem Tov's life. This book goes farther than any previous work in uncovering the historical Israel ben Eliezer--known as the Ba'al Shem Tov, or the Besht--the eighteenth-century Polish-Jewish mystic who profoundly influenced the shape of modern Judaism. As the progenitor of
Time itself creates advantages and disadvantages in the field of taxation. The timing of the recognition of income and expenses for tax purposes has two main implications: firstly, for the timing of the collection of tax, and secondly, for the question of quantification, i.e., how to ensure that the difference between the timing of the recognition of income or expenses, as opposed to the respective dates on which the amounts are actually received or paid, does not distort the determination of the amount of chargeable income. The time component is a weapon in the confrontation between the opposing motivations of the taxpayers and the tax authorities. In any given fiscal year, taxpayers seek to present a minimal picture of their chargeable income, by "deferring" the recognition of income or "advancing" the recognition of expenses. As opposed to this, the tax authorities adopt the opposite strategy: maximizing taxable "profit" in any given year. This book critically examines the various approaches that have been adopted in the tax systems in the UK, the US and Israel in relation to the timing of income recognition and expenses for tax purposes. It suggests an innovative tax model that identifies the advantages that arise to the taxpayer as a result of the differences between the timing of the recognition of income and expenses, and the timing of the receipt of the revenue or the payment of a liability, and taxes only that advantage.
