This text prepares first-year graduate students and advanced undergraduates for empirical research in economics, and also equips them for specialization in econometric theory, business, and sociology.
This book deals with the effect of crystal symmetry in determining the tensor properties of crystals. Although this is a well-established subject, the author provides a new approach using group theory and, in particular, the method of symmetry coordinates, which has not been used in any previous book. Using this approach, all tensors of a given rank and type can be handled together, even when they involve very different physical phenomena. Applications to technologically important phenomena as diverse as the electro-optic, piezoelectric, photoelastic, piezomagnetic, and piezoresistance effects, as well as magnetothermoelectric power and third-order elastic constants, are presented. Attention is also given to 'special magnetic properties', that is those that require the concepts of time reversal and magnetic symmetry, an important subject not always covered in other books in this area. This book will be of interest to researchers in solid-state physics and materials science, and will al
This classic book is essential reading for all those interested in the development of modern physics. Sir Arthur Eddington's account of the general theory of relativity, 'without,' as he says in his preface, 'introducing anything very technical in the way of mathematics, physics or philosophy', was first published in the exciting days of 1920 soon after the first objective tests of the theory had demonstrated its validity. The book was at once received with acclamation by reviewers and remains today one of the simplest and most straightforward accounts in print. The reviewer in the Athenaeum described it as 'a masterly book. The arrangement, the vigour and ease of the reasoning, the felicity of illustration, the clear, flexible prose and (we must mention it) the wit, make this book one of the most adequate and engaging attempts at the non-technical exposition of a scientific theory that it has ever been our good fortune to encounter.' This reissue includes a foreword by Sir Hermann
