This book provides a concise introduction to both the special theory of relativity and the general theory of relativity. The format is chosen to provide the basis for a single semester course which can take the students all the way from the foundations of special relativity to the core results of general relativity: the Einstein equation and the equations of motion for particles and light in curved spacetime. To facilitate access to the topics of special and general relativity for science and engineering students without prior training in relativity or geometry, the relevant geometric notions are also introduced and developed from the ground up. Students in physics, mathematics or engineering with an interest to learn Einstein's theories of relativity should be able to use this book already in the second semester of their third year. The book could also be used as the basis of a graduate level introduction to relativity for students who did not learn relativity as part of their undergraduate training.

This text of new work by leading international scholars considers developments in the study of historical linguistics and grammatical theory. It then tests their value and applicability by examining diachronic transmission of syntax at different times and in a wide range of languages

First published in 1987. An attractive feature of nonverbal communication as a research area is that it has captured the interest of scholars of different disciplinary backgrounds psychologists, linguists, anthropologists, psychiatrists, and sociologists with each discipline bringing to the area its peculiar theoretical and methodological perspectives and biases. Each of these disciplines also tend to have a favorite topic or problem area within the general domain of nonverbal communication. Along with the varying yet overlapping topical concerns that the different disciplines bring to the area of nonverbal communication are major differences in methodology. The sections into which the book is divided roughly organize the chapters in terms of their concerns with the bodily structures and zones that are involved in nonverbal behavior.

The most important work ever produced in the field of physiological optics, this classic is a model of scientific method and logical procedure, and it remains unmatched in its thorough and accessible approach. This is the third in a three-volume republication of the definitive English translation of Handbuch der Physiologischen Optik, originally published by The Optical Society of America in 1924 and containing everything that was known about physiological optics up until that time. The substratum consists of the data that Helmholtz furnished in the two nineteenth-century German editions that appeared during his lifetime. These volumes also contain extensive supplementary matter that Nagel, Gullstrand, and Kries incorporated in the third German edition of 1911, as well as significant new material prepared for the 1924 English translation by C. Ladd-Franklin, Gullstrand, and Kries, with copious annotations by James P. C. Southall that brought the work up to date with current research. Volumes I and II discuss the dioptrics of the eye and the sensations of vision;Volume III examines the perceptions of vision. Its topics include eye movements; the monocular field of vision; direction of vision; perception of depth; binocular vision; and many other highly important topics. Appendixes cover later findings on spatial configuration in vision and the theory of binocular instruments. Indexes for all three volumes are organized by subject and author.
