Few scientific communities have been more thoroughly studied than 20th-century German physicists. Yet their behavior and patterns of thinking immediately after the war remains puzzling. During the first five postwar years they suspended their internecine battles and a strange solidarity emerged. Former enemies were suddenly willing to exonerate each other blindly and even morally upright physicists began to write tirades against the 'denazification mischief' or the 'export of scientists'. Personal idiosyncracies melded into a strangely uniform pattern of rejection or resistance to the Allied occupiers, with attendant repressed feelings and self-pity. Politics was once again perceived as remote, dirty business. It was feared that the least concession of guilt would bring down even more severe sanctions on their discipline. Using tools from the history of mentality, such as analysis of serial publications, these tendenciesare examined. The perspective of emigre physicists, as reflected in their private letters and reports, embellish this portrait.
Ever since the boom of spectrum analysis in the 1860s, spectroscopy has become one of the most fruitful research technologies in analytic chemistry, physics, astronomy, and other sciences. This book is the first in-depth study of the ways in which various types of spectra, especially the sun's Fraunhofer lines, have been recorded, displayed, and interpreted. The book assesses the virtues and pitfalls of various types of depictions, including hand sketches, woodcuts, engravings, lithographs and, from the late 1870s onwards, photomechanical reproductions. The material of a 19th-century engraver or lithographer, the daily research practice of a spectroscopist in the laboratory, or a student's use of spectrum posters in the classroom, all are looked at and documented here. For pioneers of photography such as John Herschel or Hermann Wilhelm Vogel, the spectrum even served as a prime test object for gauging the color sensitivity of their processes. This is a broad, contextual portrayal of the visual culture of spectroscopy in the 19th and early 20th centuries. The illustrations are not confined to spectra--they show instruments, laboratories, people at work, and plates of printing manuals. The result is a multifacetted description, focusing on the period from Fraunhofer up to the beginning of Bohr's quantum theory. A great deal of new and fascinating material from two dozen archives has been included. A must for anyone interested in the history of modern science or in research practice using visual representations.
Focusing on the "Einstein Tower," an architecturally historic observatory built in Potsdam in 1920, this book investigates German scientific life by blending biography, architectural history, scientific theory and research, and scientific politics.
This book aims to provide a synthesis of the history, generation, use, and transfer of images in scientific practice. It delves into the rich reservoir of case studies on visual representations in scientific and technological practice that have accumulated over the past couple of decades by historians, sociologists, and philosophers of science. The main aim is thus located on the meta-level. It adopts an integrative view of recurrently noted general features of visual cultures in science and technology, something hitherto unachieved and believed by many to be a mission impossible. By systematic comparison of numerous case studies, the purview broadens away from myopic microanalysis in search of overriding patterns. The many different disciplines and research areas involved encompass mathematics, technology, natural history, medicine, the geosciences, astronomy, chemistry, and physics. The chosen examples span the period from the Renaissance to the late 20th century. The broad range of visual representations in scientific practice is treated, as well as schooling in pattern recognition, design and implementation of visual devices, and a narrowing in on the special role of illustrators and image specialists.

This book is offers a broad, comparative survey of a booming field within the history of science: the history, generation, use, and function of images in scientific practice. It explores every aspect of visuality in science, arguing for the concept of visual domains. What makes a good scientific image? What cultural baggage is essential to it? Is science indeed defined by its pictures? This book aims to provide a synthesis of the history, generation, use, and transfer of images in scientific practice.

This book reviews the current state of the theory of pattern formation by a liquid-solid interface during crystal growth. It gives a pedagogical introduction to the subject, including experimental results, mathematical modeling and linear stability analysis. After highlighting the success of the theory in resolving the selection problem of dendritic growth, various new directions of research are presented in which progress has been made recently. These are the formation of nondendritic seaweed-like structures, growth of lamellar eutectics and rapid solidification. The interplay between analytic methods on the one hand (scaling arguments, asymptotic analysis, similarity equation, Sivashinsky singular expansion) and numerical calculations on the other (Newton method, dynamical schemes) is emphasized.
More than 80 personalities, in or from Germany, that over the centuries have shaped the development of analytical chemistry are introduced by brief biographies. These accounts go beyond summarising key biographical information and outline the individual's contributions to analytical chemistry. This richly illustrated Brief offers a unique resource of information that is not available elsewhere.
NMR spectroscopy is the most valuable and versatile analytical tool in chemistry. While excellent monographs exist on high-resolution NMR in liquids and solids, this is the first book to address multidimensional solid-state NMR. Multidimensional techniques enable researchers to obtain detailed information about the structure, dynamics, orientation, and phase separation of solids, which provides the basis of a better understanding of materials properties on the molecular level.Dramatic progress-much of it pioneered by the authors-has been achieved in this area, especially in synthetic polymers. Solid-state NMR now favorably competes with well-established techniques, such as light, x-ray, or neutron scattering, electron microscopy, and dielectric and mechanical relaxation.The application of multidimensional solid-state NMR inevitably involves use of concepts from different fields of science. This book also provides the first comprehensive treatment of both the new experimental techniques and the theoretical concepts needed in more complex data analysis. The text addresses spectroscopists and polymer scientists by treating the subject on different levels; descriptive, technical, and mathematical approaches are used when appropriate. It presents an overview of new developments with numerous experimental examples and illustrations, which will appeal to readers interested in both the information content as well as the potential of solid-state NMR. The book also contains many previously unpublished details that will be appreciated by those who want to perform the experiments. The techniques described are applicable not only to the study of synthetic polymers but to numerous problems in solid-state physics, chemistry, materials science, and biophysics. - Presents original theories and new perspectives on scattering techniques - Provides a systematic treatment of the whole subject - Gives readers access to previously unpublished material - Includes extensive illustrations

Ruthenberg highlights the unique aspects of chemistry, specifically its metachemical fundamentals, which have been largely overlooked in current philosophies of science. Conventional metaphysics, derived from or focused on theoretical physics, is inadequate when applied to chemistry. The author examines and integrates historical and philosophical perspectives on important aspects of chemistry, including affinity, compositionism, emergence, synthesis/analysis, atomism/non-atomism, chemical species, chemical bond, chemical concepts, plurality, temporality/potentiality, reactivity, and underdetermination. To accomplish this, he draws on the works of notable chemists such as František Wald, Wilhelm Ostwald, Friedrich Paneth, and Hans Primas, who have contributed to the philosophical understanding of chemistry. The central conclusion of this study aligns with Immanuel Kant's viewpoint: Chemistry is a systematic art.
With more than fifty period photos and documents, countless letters and a foreword by E. D. Blodgett, F. P. Grove in Europe and Canada represents the definitive biography of the writer Northrop Frye called a "Canadian Dreiser." This work will prove an invaluable resource for scholars in Canadian and German literature, comparative literature, modernism, publishing history and translation studies."--BOOK JACKET.
That English has no diminutives is a common myth. The present study shows, however, that English does possess diminutives, and not only analytic but also synthetic diminutive markers. Analytic markers include, first and foremost, little, as well as other adjectives from the same word field, whereas the inventory of synthetic markers comprises suffixes as, for instance, -ie, -ette, -let, -kin, -een, -s, -er, -poo and -pegs. These markers are examined from a grammatical and a pragmatic perspective in an integrative formal-functional framework. The grammatical perspective involves phonological, morphological and semantic features, while the pragmatic perspective involves pragmalinguistic as well as sociopragmatic features on the levels of the speech act and larger interactive units in dialogue. The findings reveal that English diminutive suffixes are, in fact, among the most productive suffixes of the English language. While the suffixes share a number of features, each has developed its own profile, specifically regarding semantic and pragmatic features. In everyday conversation, there is a division of labour between the synthetic and the analytic type of formation concerning the communicative functions of diminutives and their distribution in discourse. The choice of formal device and its function depend crucially on pragmatic factors, notably on the illocution, the interactive status, the realisation strategy, and the politeness value of the utterances in which diminutives are employed, and also on the relationship between the interlocutors.
The German contribution in a famous Turkish victory at Gallipoli has been overshadowed by the Mustafa Kemal legend. The commanding presence of German General Liman von Sanders in the operations is well known. But relatively little is known about the background of German military intervention in Ottoman affairs. Klaus Wolf fills this gap as a result of extensive research in the German records and the published literature. He examines the military assistance offered by the German Empire in the years preceding 1914 and the German involvement in ensuring that the Ottomans fought on the side of the Central Powers and that they made best use of the German military and naval missions. He highlights the fundamental reforms that were required after the battering the Turks received in various Balkan wars, particularly in the Turkish Army, and the challenges that faced the members of the German missions. When the allied invasion of Gallipoli was launched, German officers became a vital part of a robust Turkish defense – be it at sea or on land, at senior command level or commanding units of infantry and artillery. In due course German aviators were to be, in effect, founding fathers of the Turkish air arm; whilst junior ranks played an important part as, for example, machine gunners. This book is not only their missing memorial but a missing link in understanding the tragedy that was Gallipoli.
Inflammatory cell recruitment requires the concerted action of at least five major sets of adhesion molecules: integrins, immunoglobulin-like molecules, selectins, carbohydrate structures serving as selectin ligands, and certain ectoenzymes. This volume gives a comprehensive overview on the most relevant leukocyte and endothelial adhesion molecules. The chapters are written by leaders in the field and focus on the biology, structure, function, and regulation of adhesion molecules. Currently approved adhesion molecule-based therapies are reviewed and an outlook for future approaches is also provided. The book is of interest to clinicians and scientists from immunology, physiology, cancer research, rheumatology, allergology, infectious diseases, gastroenterology, pulmonology and cardiology.
This book is devoted to non-destructive materials characterization (NDMC) using different non-destructive evaluation techniques. It presents theoretical basis, physical understanding, and technological developments in the field of NDMC with suitable examples for engineering and materials science applications. It is written for engineers and researchers in R&D, design, production, quality assurance, and non-destructive testing and evaluation. The relevance of NDMC is to achieve higher reliability, safety, and productivity for monitoring production processes and also for in-service inspections for detection of degradations, which are often precursors of macro-defects and failure of components. Ultrasonic, magnetic, electromagnetic and X-rays based NDMC techniques are discussed in detail with brief discussions on electron and positron based techniques.

In addition there is now an even stronger focus on real-life examples, with 20% more case studies taken from science and industry. For ease of comprehension the text is backed by more than 590 images which include graphic visualizations and more than 300 infrared thermography figures. The latter include many new ones depicting, for example, spectacular views of phenomena in nature, sports, and daily life.
Introduction to Methods for Nondestructive Characterization of Materials Microstructure and Materials Properties During Production, Operation, and Inspection
Introduction to Methods for Nondestructive Characterization of Materials Microstructure and Materials Properties During Production, Operation, and Inspection
Nondestructive testing (NDT) is used to examine the ability of materials and components to withstand loads. Two features of NDT are defect inspection and materials characterization. Because of the increasing ability to manufacture materials and products "defect free" there is less need for defect-oriented NDT but an increasing need for materials characterization. This book is the first comprehensive work on materials characterization, presenting the state of the art and practical applications. Materials characterization is used during production, operations, service intervals, or after repairs. Materials are used to withstand mechanical, thermal, chemical, and irradiation loads-or a combination thereof. The ability to withstand these loads is essentially a function of parameters like chemical composition, microstructure, macrostructure, residual stresses, and materials properties. The physical background of NDT is presented along with its different methods. Ultrasonics, electromagnetics, and X-rays are treated with appropriate detail, while other methods such as acoustic emission, vibration analysis, optical, and thermal methods are also covered. The different methods of materials characterization are discussed following the goal parameters, from atomic to macroscopic dimensions. One of the practical features of the book is the presentation of real world applications. On-line process control and condition monitoring are discussed, as well as off-line applications for materials characterization after production and after operation.
Part I of this report discusses the short- and medium-term growth prospects for countries in the Middle East and North Africa (MENA). The region is expected to grow at a subdued rate of 0.6 percent in 2019, rising to 2.6 percent in 2020 and 2.9 percent in 2021. The growth forecast for 2019 is revised down by 0.8 percentage points from the April 2019 projection. MENA’s economic outlook is subject to substantial downside risks—most notably, intensified global economic headwinds and rising geopolitical tensions. Part II argues that promoting fair competition is key for MENA countries to complete the transition from an administered to a market economy. Part II first examines current competition policies in MENA countries and to promote fair competition calls for strengthening competition law and enforcement agencies. It also calls for corporatizing state-owned enterprises, promoting the private sector and creating a level-playing field between them. Any moves to reform MENA economies would be aided by professional management of public assets, which could tap into a new source of national wealth.
A comprehensive review of ion beam application in modern materials research is provided, including the basics of ion beam physics and technology. The physics of ion-solid interactions for ion implantation, ion beam synthesis, sputtering and nano-patterning is treated in detail. Its applications in materials research, development and analysis, developments of special techniques and interaction mechanisms of ion beams with solid state matter result in the optimization of new material properties, which are discussed thoroughly. Solid-state properties optimization for functional materials such as doped semiconductors and metal layers for nano-electronics, metal alloys, and nano-patterned surfaces is demonstrated. The ion beam is an important tool for both materials processing and analysis. Researchers engaged in solid-state physics and materials research, engineers and technologists in the field of modern functional materials will welcome this text.
This book focuses on the gradual formation of the concept of ‘light quanta’ or ‘photons’, as they have usually been called in English since 1926. The great number of synonyms that have been used by physicists to denote this concept indicates that there are many different mental models of what ‘light quanta’ are: simply finite, ‘quantized packages of energy’ or ‘bullets of light’? ‘Atoms of light’ or ‘molecules of light’? ‘Light corpuscles’ or ‘quantized waves’? Singularities of the field or spatially extended structures able to interfere? ‘Photons’ in G.N. Lewis’s sense, or as defined by QED, i.e. virtual exchange particles transmitting the electromagnetic force? The term ‘light quantum’ made its first appearance in Albert Einstein’s 1905 paper on a “heuristic point of view” to cope with the photoelectric effect and other forms of interaction of light and matter, but the mental model associated with it has a rich history both before and after 1905. Some of its semantic layers go as far back as Newton and Kepler, some are only fully expressed several decades later, while others initially increased in importance then diminished and finally vanished. In conjunction with these various terms, several mental models of light quanta were developed—six of them are explored more closely in this book. It discusses two historiographic approaches to the problem of concept formation: (a) the author’s own model of conceptual development as a series of semantic accretions and (b) Mark Turner’s model of ‘conceptual blending’. Both of these models are shown to be useful and should be explored further. This is the first historiographically sophisticated history of the fully fledged concept and all of its twelve semantic layers. It systematically combines the history of science with the history of terms and a philosophically inspired history of ideas in conjunction with insights from cognitive science.
Subject of the book is MR imaging in all kinds of diseases that may affect the skull and brain. Primary purpose of the book is to provide the reader with a descriptive as well as pictorial overview of MRI in the various pathologic processes. An important additional purpose is to explain how to make the best use of MRI if a particular disease is suspected. Extensive information on differential diagnosis will also be included.
today, the name RKW Architektur + Städtebau evokes two hundred architects whose work never fails to convince. The reason does not lie in the narrowly defined architectural language of individual leaders of the firm. More than in any other firm, the various teams are given generous latitude for independent initiative. Thus, this documentation of the last ten years, with cross - references to the development of this unique partnership since 1950, doesn’t just present sixty - five structures and projects from an internationally sought - after firm. On the contrary, in its search for the secret of the firm’s success, it looks behind the scenes in numerous interviews and essays. The works considered range from the research facilities for AUDI, the new sciences campus of RWTH Aachen University, and the corporate headquarters of Vodafone, Debitel, and Arag to urban revitalization projects, residential buildings, schools, sports halls, railroad stations, city halls, banks, urban office buildings and shopping centers, and the stadium for the 2012 European Soccer Championship in Gdansk.
The original edition of this ambitious reference was published in hardcover in 1998, in two oversize volumes (10x13"). This edition combines the two volumes into one; it's paperbound ("flexi-cover"--the paper has a plastic coating), smaller (8x10", and affordable for art book buyers with shallower pockets--none of whom should pass it by. The scope is encyclopedic: half the work (originally the first volume) is devoted to painting; the other half to sculpture, new media, and photography. Chapters are arranged thematically, and each page displays several examples (in color) of work under discussion. The final section, a lexicon of artists, includes a small bandw photo of each artist, as well as biographical information and details of work, writings, and exhibitions. Ruhrberg and the three other authors are veteran art historians, curators, and writers, as is editor Walther. c. Book News Inc.
[The author] has done a great service to historians of modern physics by editing this first anthology of primary sources, excellently translated into English... The texts are well selected and range widely, from private correspondence and official memoranda to articles dealing with physics in a propagandistic or popular manner... Many of the sources are extremely interesting and appear here for the first time. Their value is further enhanced by the editor's cross-referencing and detailed notes... [The book] is also a fine introduction to the entire subject. [The] 101-page 'introduction' gives an admirable survey of German physics during the Nazi period as well as a thorough discussion of the historiography of the subject... [The book] is of such quality and usefulness that were I to choose a single book on the history of physics in the Third Reich this might well be the one." H. Kragh, Centaurus
