Blokhintsev English | PDF | 1973 | 341 Pages | ISBN : 9027702403 | 20.6 MB A way of understanding the laws which govem the worId of elementary particIes has not been found yet. Present-day theoretical physicists have to be satisfied with compromises which, at the best, promise some success at the expense of generality and unity. U nder these circumstances a critical analysis of the basic concepts of modem quantum theory may be timely and usefuI. It is hoped that the value of such an analysis may be preserved even if, in the near future, new ways of understanding the basis of elementary particIe physics are discovered. In this monograph one specific aspect of this analysis is treated, namely the problems of geometry in the microworld. An out line of geometrical measurements in the macroworld was given pre viously. These measurements seem to be c1ear enough for at least a certain set of problems to be considered as a starting point for discussing the situation in the microworld. The concepts and methods which are useful in the macroworld may only indirectly be carried over into the microworld and they require a high degree of abstraction. In comprehending the physical content of dynamic variables which have geometric meaning, for example, the space-time partic1e coor dinates x, y, z, t it is of ten necessary to have recourse to gedanken experiments which, although not feasible in practice, can nevertheless be compatible with the basic principles of geometry and quantum mechanics.  Free Download Space Fostering African Societies: Developing the African Continent Through Space, Part 5 by Annette Froehlich English | PDF EPUB (True) | 2023 | 115 Pages | ISBN : 3031367464 | 18.4 MB This peer-reviewed book provides detailed insights into how space and its applications are, and can be used to support the development of the full range and diversity of African societies, as encapsulated in the African Union's Agenda 2063. Following on from Part 1 to Part 4, which were highly acclaimed by the space community, it focuses on the role of space in supporting the UN Sustainable Development Goals in Africa, but covers an even more extensive array of relevant and timely topics addressing all facets of African development. It demonstrates that, while there have been significant achievements in recent years in terms of economic and social development, which have lifted many of Africa's people out of poverty, there is still a great deal that needs to be done to fulfill the basic needs of Africa's citizens and afford them the dignity they deserve. To this end, space is already being employed in diverse fields of human endeavor to serve Africa's goals for its future, but there is much room for further incorporation of space systems and data. Providing a comprehensive overview of the role space is playing in helping Africa achieve its developmental aspirations, the book will appeal to both students and professionals in fields such as space studies, international relations, governance, social, rural and technical development.  Free Download Sozialrechtsbezogene Beratung: Eine empirische Analyse zur Herstellung des Zugangs zum System sozialer Sicherung by Katharina Weyrich Deutsch | PDF EPUB (True) | 2023 | 247 Pages | ISBN : 3658435240 | 6.6 MB In diesem Buch wird erstmals die sozialrechtsbezogene Beratung von Verbänden als Strategie im Zugang zum Recht in die Tiefe gehend analysiert und anhand von drei exemplarisch dargestellten Beratungssituationen die Herstellung eines Zugangs zum System sozialer Sicherung rekonstruiert. Die Beratung der Sozialverbände zu sozialen Problemlagen ist ein historisch gewachsenes Gefüge im Sozialstaat. Sie tragen mit ihrer Beratung dazu bei, dass Bürger:innen im Bedarfsfall Barrieren im Zugang zum System sozialer Sicherung überwinden und auf die sozialen Sicherungssysteme zugreifen können. Die Gestaltung des Beratungssettings ist dabei von ausschlaggebender Bedeutung.  Free Download Y. Subbarayalu, "South India Under the Cholas" English | ISBN: 0198077351 | 2012 | 274 pages | PDF | 22 MB This book explores different aspects of state-society interactions in medieval south India under the reign of the Cholas. Divided into two parts-Epigraphy and History, and State and Society-the first provides an in-depth analysis of Tamil epigraphy and inscriptions. While interpreting inscriptional terminology, it discusses the socio-economic milieu, merchant guilds, and other sociological aspects. The next section traces the evolution of the medieval state, economy, and society. It discusses land surveys, Chola revenue system and sale deeds, and property rights. The author examines, in detail, the emergence of new organizations like Urar, Nattar, and Periyanattar, and maritime trade guilds, and social classes like landholders, cultivators, slaves, and the left and right hand divisions. The introduction contextualizes these essays in current research scenario and historiography and also provides a brief overview of the evolution of the Chola state and society.  Free Download Héctor Fernández L'Hoeste, "Sound, Image, and National Imaginary in the Construction of Latin/o American Identities " English | ISBN: 1498565239 | 2017 | 244 pages | EPUB | 6 MB Sound, Image, and National Imaginary in the Construction of Latin/o American Identities addresses a gap in the many narratives discussing the cultural histories of Latin American nations, particularly in terms of the birth, configuration, and perpetuation of national identities. It argues that these processes were not as gradual or constrained as traditionally conceived. The actual circumstances dictating the adoption of particular technologies for the representation of national ideas shifted and varied according to many factors including local circumstances, political singularities, economic disparities, and highly individualized cultural transitions. This book proposes a model of chronology that is valid not only for nations that underwent strong processes of nationalism during the early or mid-twentieth century, but also for those that experienced highly idiosyncratic cultural, economic, and political development into the early twenty-first century.

Sanchez's haiku, as an integral and prominent part of contemporary African American poetry, have expressed not only her ideas of nature, beauty, and harmony but also her aesthetic experience of music, culture, and love. Aesthetically, this experience reflects a poetic mind which has helped the poet to shape or reimage her poetic spirit.  Free Download J. Cheryl Exum, "Song of Songs: An Introduction and Study Guide: The Bible's Only Love Poem " English | ISBN: 0567674711 | 2022 | 136 pages | PDF | 12 MB The Song of Songs, also known as the Song of Solomon, is an unusual book to find in the Bible. As the Bible's only love poem, the Song offers a unique picture of relations between the sexes in biblical times. Unlike other biblical books, it consists entirely of dialogue. It looks at love from both a woman's and a man's point of view, and shows the reader what love is like exclusively through what lovers say about it.  Free Download Arthur Krystal, "Some Unfinished Chaos: The Lives of F. Scott Fitzgerald" English | ISBN: 0813950619 | 2023 | 232 pages | EPUB | 411 KB Surely enough has been written about F. Scott Fitzgerald, the man who coined "the Jazz Age" and symbolized the Roaring Twenties, whose very name conjures up a meteoric rise and an equally spectacular fall? But the better question might be, Why has so much ink been spent on a writer who completed only four novels, who fell from grace in the 1930s only to be resurrected twenty years later? The answer, according to the cultural critic Arthur Krystal, "is the problem that is Fitzgerald."
