This unique textbook presents a novel, axiomatic pedagogical path from classical to quantum physics. Readers are introduced to the description of classical mechanics, which rests on Euler’s and Helmholtz’s rather than Newton’s or Hamilton’s representations. Special attention is given to the common attributes rather than to the differences between classical and quantum mechanics. Readers will also learn about Schrödinger’s forgotten demands on quantization, his equation, Einstein’s idea of ‘quantization as selection problem’. The Schrödinger equation is derived without any assumptions about the nature of quantum systems, such as interference and superposition, or the existence of a quantum of action, h. The use of the classical expressions for the potential and kinetic energies within quantum physics is justified. Key features: · Presents extensive reference to original texts. · Includes many details that do not enter contemporary representations of classical mechanics, although these details are essential for understanding quantum physics. · Contains a simple level of mathematics which is seldom higher than that of the common (Riemannian) integral. · Brings information about important scientists · Carefully introduces basic equations, notations and quantities in simple steps This book addresses the needs of physics students, teachers and historians with its simple easy to understand presentation and comprehensive approach to both classical and quantum mechanics..
This volume brings together a set of classic essays on early rabbinic history and culture, seven of which have been translated into English especially for this publication. The studies are presented in three sections according to theme: (1) sources, methods and meaning; (2) tradition and self-invention; and (3) rabbinic contexts. The first section contains essays that made a pioneering contribution to the identification of sources for the historical and cultural study of the rabbinic period, articulated methodologies for the study of rabbinic history and culture, or addressed historical topics that continue to engage scholars to the present day. The second section contains pioneering contributions to our understanding of the culture of the sages whose sources we deploy for the purposes of historical reconstruction, contributions which grappled with the riddle and rhythm of the rabbis’ emergence to authority, or pierced the veil of their self-presentation. The essays in the third section made contributions of fundamental importance to our understanding of the broader cultural contexts of rabbinic sources, identified patterns of rabbinic participation in prevailing cultural systems, or sought to define with greater precision the social location of the rabbinic class within Jewish society of late antiquity. The volume is introduced by a new essay from the editor, summarizing the field and contextualizing the reprinted papers. About the series Classic Essays in Jewish History (Series Editor: Kenneth Stow) The 6000 year history of the Jewish peoples, their faith and their culture is a subject of enormous importance, not only to the rapidly growing body of students of Jewish studies itself, but also to those working in the fields of Byzantine, eastern Christian, Islamic, Mediterranean and European history. Classic Essays in Jewish History is a library reference collection that makes available the most important articles and research papers on the development of Jewish communities across Europe and the Middle East. By reprinting together in chronologically-themed volumes material from a widespread range of sources, many difficult to access, especially those drawn from sources that may never be digitized, this series constitutes a major new resource for libraries and scholars. The articles are selected not only for their current role in breaking new ground, but also for their place as seminal contributions to the formation of the field, and their utility in providing access to the subject for students and specialists in other fields. A number of articles not previously published in English will be specially translated for this series. Classic Essays in Jewish History provides comprehensive coverage of its subject. Each volume in the series focuses on a particular time-period and is edited by an authority on that field. The collection is planned to consist of 10 thematically ordered volumes, each containing a specially-written introduction to the subject, a bibliographical guide, and an index. All volumes are hardcover and printed on acid-free paper, to suit library needs. Subjects covered include: The Biblical Period The Second Temple Period The Development of Jewish Culture in Spain Jewish Communities in Medieval Central Europe Jews in Medieval England and France Jews in Renaissance Europe Jews in Early Modern Europe Jews under Medieval Islam Jews in the Ottoman Empire and North Africa
As a novelist, art critic, and cultural historian, Booker Prize-winning author John Berger is a writer of dazzling eloquence and arresting insight whose work amounts to a subtle, powerful critique of the canons of our civilization. In About Looking he explores our role as observers to reveal new layers of meaning in what we see. How do the animals we look at in zoos remind us of a relationship between man and beast all but lost in the twentieth century? What is it about looking at war photographs that doubles their already potent violence? How do the nudes of Rodin betray the threats to his authority and potency posed by clay and flesh? And how does solitude inform the art of Giacometti? In asking these and other questions, Berger quietly -- but fundamentally -- alters the vision of anyone who reads his work.
A moving collection of autobiographical essays from a Russian poet and refugee of the Bolshevik Revolution. Marina Tsvetaeva ranks with Anna Akhmatova, Osip Mandelstam, and Boris Pasternak as one of Russia’s greatest twentieth-century poets. Her suicide at the age of forty-eight was the tragic culmination of a life buffeted by political upheaval. The essays collected in this volume are based on diaries she kept during the turbulent years of the Revolution and Civil War. In them she records conversations of women in the markets, soldiers and peasants on the train traveling from the Crimea to Moscow in October 1917, fighting in the streets of Moscow, a frantic scramble with co-workers to dig frozen potatoes out of a cellar, and poetry readings organized by a newly minted Soviet bohemia. Alone in Moscow with two small children, no income, and a missing husband, Tsvetaeva struggled to feed her daughters (one of whom died of malnutrition in an orphanage), find employment in the Soviet bureaucracy, and keep writing poetry. Her keen and ruthless eye observes with compassion and humor—bringing the social, economic, and cultural chaos of the period to life. These autobiographical writings not only give a vivid eyewitness account of Russian history but provide vital insights into the workings of Tsvetaeva’s unique poetics. Includes black and white photographs.
