A lifetime of candid reflections from physicist Freeman Dyson, “an acute observer of personality and human foibles” (New York Times Book Review). Written between 1940 and the late 1970s, the postwar recollections of renowned physicist Freeman Dyson have been celebrated as an historic portrait of modern science and its greatest players, including Robert Oppenheimer, Richard Feynman, Stephen Hawking, and Hans Bethe. Chronicling the stories of those who were engaged in solving some of the most challenging quandaries of twentieth-century physics, Dyson lends acute insight and profound observations to a life’s work spent chasing what Einstein called those “deep mysteries that Nature intends to keep for herself.” Whether reflecting on the drama of World War II, the moral dilemmas of nuclear development, the challenges of the space program, or the demands of raising six children, Dyson’s annotated letters reveal the voice of one “more creative than almost anyone else of his generation” (Kip Thorne). An illuminating work in these trying times, Maker of Patterns is an eyewitness account of the scientific discoveries that define our modern age.

Modelling Of Patterns In Space And Time

This volume contains a selection of papers presented at the work shop "Modelling of Patterns in Space and Time", organized by the 80nderforschungsbereich 123, "8tochastische Mathematische Modelle", in Heidelberg, July 4-8, 1983. The main aim of this workshop was to bring together physicists, chemists, biologists and mathematicians for an exchange of ideas and results in modelling patterns. Since the mathe matical problems arising depend only partially on the particular field of applications the interdisciplinary cooperation proved very useful. The workshop mainly treated phenomena showing spatial structures. The special areas covered were morphogenesis, growth in cell cultures, competition systems, structured populations, chemotaxis, chemical precipitation, space-time oscillations in chemical reactors, patterns in flames and fluids and mathematical methods. The discussions between experimentalists and theoreticians were especially interesting and effective. The editors hope that these proceedings reflect at least partially the atmosphere of this workshop. For the convenience of the reader, the papers are ordered alpha betically according to authors. However, the table of contents can easily be grouped into the main topics of the workshop. For practical reasons it was not possible to reproduce in colour the beautiful pictures of patterns shown at the workshop. Since a larger number of half-tone pictures could be included in this volume, the loss of information has, however, been kept to a minimum. The workshop has already stimulated cooperation between its parti cipants and this volume is intended to spread this effect.

This book on symmetric geometric patterns of Islamic art has educational, aesthetic, cultural and practical purposes. Its central purpose is to bring to the attention of the world in general, and the people of Islamic culture in particular, the potential of the art for providing a unified experience of science and art in the context of mathematical education. Unlike other books on Islamic patterns, this book emphasizes the educational potential in the context of modern physics, chemistry, crystallography and computer graphics. The symmetric structure of about 250 Islamic patterns is presented. Simple, but detailed original, unpublished algorithms suitable for modern computer graphics are given for the construction of two-dimensional periodic patterns. Endorsed by prominent experts from the fields of Physics to Systems and Cybernetics, this book promises to be a must-read, not only for specialised mathematicians, but also for students, graphic artists, illustrators, computer hobbyists, as well as the lay reader keen to explore Islamic art. Contents:Islamic Patterns and Their Geometrical StructuresIn Praise of Pattern, Symmetry, Unity and Islamic ArtThe Gateway from Islamic Patterns to Invariance and GroupsClassification, Identification and Construction of the Seventeen Types of Two-Dimensional Periodic PatternsIslamic Patterns and Their Symmetries Readership: General. keywords:Islamic Patterns;Islamic Tiles;Islamic Art;Muslim Art;Islamic Culture;Pattern;Symmetry;Tile;Tiling;Geometrical Pattern;Geometrical Art;Mathematical Art;Alhambra;Science and Art “Symmetry is one of the most important and pervasive principles in Mathematics, particularly in its Geometrical form. Here, mathematics combines with art and exhibits clearly its aesthetic appeal. Islamic patterns provide a marvellous illustration of symmetry and Drs. Abas and Salman perform a useful service by taking this as their theme and blending it with ideas on computer graphics.” Foreword by Michael Atiyah “… a major contribution to the world of science and of particular value to the documention of the culture of Islam.” N Gedal “… This book will allow readers to travel through time and space, from ancient ornaments to the most modern computer graphics patterns.” C Pickover “Ever since the discovery of the existence of seventeen space groups in two dimensions by Fedorov in 1891, it has been speculated that all seventeen could be found in Islamic art. But it is in this book that this remarkable fact is for the first time detailed and analysed, with beautiful illustrations. Rarely is there such a thought-provoking blend of esthetics and geometry with abstraction.” C N Yang “Abas and Salman have assembled a fascinating collection that combines art, history, culture, science, mathematics and philosophy. Their examples range from a 12th-century minaret in Uzbekistan via the Alhambra in Granada to modern computer graphics of Koranic calligraphy on dodecahedrons and tori. They conclude by speculating on the prospect of creating Islamic patterns in virtual reality, where ‘a seeker after unity in science and art would be able to submerge himself or herself in exquisite Alhambras of the mind’. Judging by the evidence presented here, it would be an unforgettable experience.” New Scientist “The authors' love for Islamic art and symmetry shines through every page of this book.” The Chemical Intelligencer “The authors' data can be used both for re-creating the original patterns as well as for the production of new variations and perhaps exploitation via CAD/CAM implementations. This involves a new method for extracting numerical data for use with computer graphics. The book is very richly illustrated with lovely color plates and some beautiful photographs.” Mathematical Reviews

This collection of essays explores the ancient affinity between the mathematical and the aesthetic, focusing on fundamental connections between these two modes of reasoning and communicating. From historical, philosophical and psychological perspectives, with particular attention to certain mathematical areas such as geometry and analysis, the authors examine ways in which the aesthetic is ever-present in mathematical thinking and contributes to the growth and value of mathematical knowledge.

Perspectives In Primary Education

PURPOSE OF THE STUDY Primary education in Europe, as in the United States and other conti nents, is passing through a period of profound change, affecting some of the fundamental educational aims at primary school level and teaching structure, content and methods. The purpose of this study is to sketch a broad picture of the Euro pean educational scene which may be brought about by the impact of innovation in industrialised countries. We are only too aware of the difficulties inherent in our task. Even when projections and forecasts are firmly rooted in an analysis of existing data, they are liable to be contradicted by the facts. We shall attempt to allow for those alternative situations which may provide the context for the organisation and functioning of primary education. We make no claim to portray the European primary school at the end of the twentieth or at the beginning of the twenty-first century. We shall do no more than analyse existing achievements and experiments based on research in the associated fields of education, psychology and sociology and from this analysis extrapolate a series of forecasts based on objective factors of a social and intellectual nature, offering realistic hypotheses for the future. Our aim is to provide sound guidelines for those who are to build a better future for our children.
