A central pillar of contemporary communication research is the analysis of filmed interactions between people. The techniques employed in such analysis first took on a recognizably modern form in the 1970s, but their roots go back to the earliest days of motion picture technology in the late nineteenth century. This book presents original essays accompanied by written responses which together create a dialogue exploring early efforts at audio-visual sequence analysis and their common goal to capture the "whole" of the communicative situation. The first three chapters of this volume look at the film-based research of Gestalt psychologists in Berlin as well as psychologists in the orbit of Karl and Charlotte Bühler in Vienna in the first decades of the twentieth century. Most of these figures – along with many other Central European scholars of this era – were driven into exile in the United States after the rise of National Socialism in the 1930s. This scientific migration led to the cross-pollination of communication studies in America, an outcome visible in the leading project in interaction research of the mid-twentieth century, the Natural History of an Interview. The following two chapters examine this project in its historical context. The volume closes with a critical edition of a treasure from the archives: the transcript of a speech delivered by Ray Birdwhistell, a key participant in the Natural History of an Interview project and founder of kinesics.
Thirteen papers on different subjects, focussing on writings and inscriptions in medieval art, explore the faculty of writing to create and determine spaces and to generate the sacred by the display of holy scripture. The subjects range from book illumination over wall painting, mosaics, sculpture, and church interiors to inscriptions on portals and façades.
Despite the rapidly expanding ambit of physical research and the continual appearance of new branches of physics, the main thrust in its development was and is the attempt at a theoretical synthesis of the entire body of physical knowledge. The main triumphs in physical science were, as a rule, associ ated with the various phases of this synthesis. The most radical expression of this tendency is the program of construction of a unified physical theory. After Maxwellian electrodynamics had unified the phenomena of electricity, magnetism, and optics in a single theoretical scheme on the basis of the con cept of the electromagnetic field, the hope arose that the field concept would become the precise foundation of a new unified theory of the physical world. The limitations of an electromagnetic-field conception of physics, however, already had become clear in the first decade of the 20th century. The concept of a classical field was developed significantly in the general theory of relativity, which arose in the elaboration of a relativistic theory of gravitation. It was found that the gravitational field possesses, in addition to the properties inherent in the electromagnetic field, the important feature that it expresses the metric structure of the space-time continuum. This resulted in the following generalization of the program of a field synthesis of physics: The unified field representing gravitation and electromagnetism must also describe the geometry of space-time.
This book presents two plays, both of which are translated into English for the first time. In Voyage to the Sonorous Land, or The Art of Asking, a cockeyed optimist and a spoilsport lead a group of characters to the hinterland of their imaginations, where they search not for the right answers but for the questions. The Hour We Knew Nothing of Each Other takes place in a city square where more than four hundred characters pass by one another without speaking a single word.
The use of the differential geometry of a Riemannian space in the mathematical formulation of physical theories led to important developments in the geometry of such spaces. The concept of parallelism of vectors, as introduced by Levi-Civita, gave rise to a theory of the affine properties of a Riemannian space. Covariant differentiation, as developed by Christoffel and Ricci, is a fundamental process in this theory. Various writers, notably Eddington, Einstein and Weyl, in their efforts to formulate a combined theory of gravitation and electromagnetism, proposed a simultaneous generalization o.
This collection of essays is intended as a tribute to Josef Maria Jauch on his sixtieth birthd~. Through his scientific work Jauch has justly earned an honored name in the community of theo retical physicists. Through his teaching and a long line of dis tinguished collaborators he has put an imprint on modern mathema tical physics. A number of Jauch's scientific collaborators, friends and admirers have contributed to this collection, and these essays reflect to some extent Jauch's own wide interests in the vast do main of theoretical physics. Josef Maria Jauch was born on 20 September 1914, the son of Josef Alois and Emma (nee Conti) Jauch, in Lucerne, Switzerland. Love of science was aroused in him early in his youth. At the age of twelve he came upon a popular book on astronomy, and an exam ple treated in this book mystified him. It was stated that if a planet travels around a centre of Newtonian attraction with a pe riod T, and if that planet were stopped and left to fall into the centre from any point of the circular orbit, it would arrive at the centre in the time T/I32. Young Josef puzzled about this for several months until he made his first scientific discovery : that this result could be derived from Kepler's third law in a quite elementary way.
