Download or read book Accurate Clock Pendulums written by Robert J. Matthys and published by OUP Oxford. This book was released on 2004-06-03 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Shortt clock, made in the 1920s, is the most famous accurate clock pendulum ever known, having an accuracy of one second per year when kept at nearly constant temperature. Almost all of a pendulum clock's accuracy resides in its pendulum. If the pendulum is accurate, the clock will be accurate. In this book, the author describes many scientific aspects of pendulum design and operation in simple terms with experimental data, and little mathematics. It has been written, looking at all the different parts and aspects of the pendulum in great detail, chapter by chapter, reflecting the degree of attention necessary for making a pendulum run accurately. The topics covered include the dimensional stability of different pendulum materials, good and poor suspension spring designs, the design of mechanical joints and clamps, effect of quartz on accuracy, temperature compensation, air drag of different bob shapes and making a sinusoidal electromagnetic drive. One whole chapter is devoted to simple ways of improving the accuracy of ordinary low-cost pendulum clocks, which have a different construction compared to the more expensive designs of substantially well-made ones. This book will prove invaluable to anyone who wants to know how to make a more accurate pendulum or pendulum clock.

Download or read book The New Cosmos written by A. Unsöld and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: to the Second Edition The development of astronomy in the last ten years has been nothing short of explosive. This second edition of The New Cosmos, considerably revised and enlarged, tries to share this development with its readers. Let us mention a few key words: from mo on landings, planetary probes, aild continental drift through pulsars, X-ray and y-ray sources, interstellar molecules, quasars, and the structure and evolution of stars and stellar systems right up to cosmological models. As before, the most important task of this book is to give a not too difficult introduction to present-day astronomy and astrophysics, both to the student of astronomy and to the specialist from a neighboring discipline. We therefore draw to the attention of the reader, as an essential part of our description, the numerous illustrations-many of them new-and their detailed captions. As far as possible we link a description of important observations with basic features of the theory. On the other hand, when it comes to detail we often content ourselves with abrief description, leaving the detailed explanation to the specialist literature. The transition to the specialist literature should be eased by the Bibliography at the end of the book. Important new investigations are noted in the text by their year, not so much for historical reasons as to enable the original work to be found in the Astronomy and Astrophysics Abstracts (1969 on).

Download or read book An Introduction to Electronic Art Through the Teaching of Jacques Lacan written by David Bard-Schwarz and published by Routledge. This book was released on 2014-01-03 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electronic art offers endless opportunities for reflection and interpretation. Works can be interactive or entirely autonomous and the viewer's perception and reaction to them may be challenged by constantly transforming images. Whether the transformations are a product of the appearances or actions of a viewer in an installation space, or a product of a self-contained computer program, is a source of constant fascination. Some viewers may feel strange or unnerved by a work, while others may feel welcoming, humorous, and playful emotions. The art may also provoke a critical response to social, aesthetic, and political aspects of early twenty-first-century life. This book approaches electronic art through the teachings of Jacques Lacan, whose return to Freud has exerted a powerful and wide-ranging influence on psychoanalysis and critical theory in the twentieth century. David Bard-Schwarz draws on his experience with Lacanian psychoanalysis, music, and interactive and traditional arts in order to address aspects of the works the viewer may find difficult to understand. Dividing his approach over four thematic chapters—Bodies, Voices, Eyes, and Signifiers—Bard-Schwarz explores the links between works of new media and psychoanalysis (how we process what we see, hear, touch, imagine, and remember). This is a fascinating book for new media artists and critics, museum curators, psychologists, students in the fine arts, and those who are interested in digital technology and contemporary culture.
