Optical interferometry is a powerful technique to make images on angular scales hundreds of times smaller than is possible with the largest telescopes. This concise guide provides an introduction to the technique for graduate students and researchers who want to make interferometric observations and acts as a reference for technologists building new instruments. Starting from the principles of interference, the author covers the core concepts of interferometry, showing how the effects of the Earth's atmosphere can be overcome using closure phase, and the complete process of making an observation, from planning to image reconstruction. This rigorous approach emphasizes the use of rules-of-thumb for important parameters such as the signal-to-noise ratios, requirements for sampling the Fourier plane and predicting image quality. The handbook is supported by web resources, including the Python source code used to make many of the graphs, as well as an interferometry simulation framework, available at www.cambridge.org/9781107042179.
Scientific and popular literature on modern cosmology is very extensive; however, scholarly works on the historical development of cosmology are few and scattered. The Oxford Handbook of the History of Modern Cosmology offers a comprehensive and authoritative account of the history of cosmology from the late nineteenth century to the early twenty-first century. It provides historical background to what we know about the universe today, including not only the successes but also the many false starts. Big Bang theory features prominently, but so does the defunct steady state theory. The book starts with a chapter on the pre-Einstein period (1860-1910) and ends with chapters on modern developments such as inflation, dark energy and multiverse hypotheses. The chapters are organized chronologically, with some focusing on theory and others more on observations and technological advances. A few of the chapters discuss more general ideas, relating to larger contexts such as politics, economy, philosophy and world views.
Roger Penrose's views on the large-scale physics of the Universe, the small-scale world of quantum physics and the physics of the mind are controversial and widely discussed. This book is a fascinating and accessible summary of Roger Penrose's current thinking on those areas of physics in which he feels there are major unresolved problems. It is also a stimulating introduction to the radically new concepts that he believes will be fruitful in understanding the workings of the brain and the nature of the human mind.
Written for advanced undergraduates, physicists, and historians and philosophers of physics, this book tells the story of the development of our understanding of quantum phenomena through the extraordinary years of the first three decades of the twentieth century. Rather than following the standard axiomatic approach, this book adopts a historical perspective, explaining clearly and authoritatively how pioneers such as Heisenberg, Schrodinger, Pauli and Dirac developed the fundamentals of quantum mechanics and merged them into a coherent theory, and why the mathematical infrastructure of quantum mechanics has to be as complex as it is. The author creates a compelling narrative, providing a remarkable example of how physics and mathematics work in practice. The book encourages an enhanced appreciation of the interaction between mathematics, theory and experiment, helping the reader gain a deeper understanding of the development and content of quantum mechanics than any other text at this level.
The Cavendish Laboratory is arguably the most famous physics laboratory in the world. Founded in 1874, it rapidly gained a leading international reputation through the researches of the Cavendish professors beginning with Maxwell, Rayleigh, J. J. Thomson, Rutherford and Bragg. Its name will always be associated with the discoveries of the electron, the neutron, the structure of the DNA molecule and pulsars, but these are simply the tip of the iceberg of outstanding science. The physics carried out in the laboratory is the central theme of the book and this is explained in reasonably non-technical terms. The research activities are set in their international context. Generously illustrated, with many pictures of the apparatus used and diagrams from the original papers, the story is brought right up to date with descriptions of the science carried out under the leadership of the very different personalities of Mott, Pippard and Edwards.
"Nicht schon wieder ein Buch uber die ersten Augenblicke des Univer- sums!" hoere ich meine Leser protestieren. Keine Sorge, dieses Buch han- delt von all den anderen Dingen, die im Universum um uns herum zu finden sind. Will man jedoch die Entwicklungsgeschichte des Univer- sums erzahlen, dann kommt man nicht darum herum zu fragen, wie all das entstanden ist, was wir im Universum beobachten. Deswegen blicken wir immer tiefer in die Vergangenheit zuruck, denn anders koen- nen wir nicht in geordneter Reihenfolge darstellen, was sich im Laufe der Zeit zugetragen hat. Dieser Blick zuruck in die Geschichte erweist sich als ungewoehnlich erfolgreich, weitaus erfolgreicher jedenfalls, als es sich die Begrunder der Astrophysik und wissenschaftlichen Kosmologie in den 30er und 40er Jahren unseres Jahrhunderts vorgestellt haben moegen. Die Ent- wicklung von Astronomie und Kosmologie gehoert zu den bemerkens- wertesten Fortschritten der modernen Naturwissenschaften seit dem Zweiten Weltkrieg. Wir haben ein Goldenes Zeitalter der Astronomie durchlebt, weil voellig unerwartete neue Beobachtungsverfahren uns neue Einblicke in das Geschehen am Himmel gewahrt haben. Niemand dachte vor 50 Jahren daran, dass man Neutronensterne durch Beobach- tungen mit langen Radiowellen entdecken wurde.
