With clear illustrations throughout and without recourse to quantum mechanics, the reader is invited to revisit unsolved problems lying at the foundations of theoretical physics. Maxwell and his contemporaries abandoned their search for a geometrical representation of the electric and magnetic fields. The wave-particle dilemma and Bose-Einstein statistical counting have resulted in unsatisfactory non-realistic interpretations. Furthermore, a simple structure of the hydrogen atom that includes hyperfine levels is still wanting.Working with the latest experimental data in photonics a proposed solution to the wave-particle dilemma is suggested based on an array of circular-polarized rays. The Bose-Einstein counting procedure is recast in terms of distinguishable elements. Finally, a vortex model of a 'particle' is developed based on a trapped photon. This consists of a single ray revolving around a toroidal surface, and allows a geometrical definition of mass, electric potential, and magnetic momentum. With the adjustment of two parameters, values to 4 dp for the hyperfine frequencies (MHz) of hydrogen can be obtained for which a computer program is available.

From quantum physics and genetics to psychology and the social sciences, from the development of atomic weapons to the growing mass media of film and radio, the early 20th century was a period of intense scientific and technological change. Modernism, Science, and Technology surveys the scientific contexts of writers from H.G. Wells and Gertrude Stein to James Joyce and Virginia Woolf and the ways in modernist writers responded to these paradigm shifts. Introducing key concepts from science studies and their implications for the study of modernist literature, the book includes chapters covering the physical sciences, mathematics, life sciences, social sciences and 'pseudosciences'. Including a timeline of key developments and guides to further reading, this is an essential guide to students and researchers studying the topic at all levels.

The breadth, scope and volume of research in atomic, molecular and optical (AMO) physics have increased enormously in the last few years. Following the widespread use of pulsed lasers, certain newly emerging areas as well as selected mature subfields are ushering in a second renaissance. This volume focuses on current research in these crucial areas: cold atoms and BoseOCoEinstein condensates, quantum information and quantum computation, and new techniques for investigating collisions and structure. The topics covered include: the multireference coupled cluster method in quantum chemistry and the role of electronic correlation in nanosystems; laser cooling of atoms and theories of the BoseOCoEinstein condensate; and quantum computing and quantum information transfer using cold atoms and shaped ultrafast pulses. Other articles deal with recent findings in heavy ion collisions with clusters, time-of-flight spectroscopy techniques, and a specific example of a chaotic quantum system. The contributions will greatly assist in the sharing of specialized knowledge among experts and will also be useful for postgraduate students striving to obtain an overall picture of the current research status in the areas covered.

This book introduces physics students and teachers to the historical development of the kinetic theory of gases, by providing a collection of the most important contributions by Clausius, Maxwell and Boltzmann, with introductory surveys explaining their significance. In addition, extracts from the works of Boyle, Newton, Mayer, Joule, Helmholtz, Kelvin and others show the historical context of ideas about gases, energy and irreversibility. In addition to five thematic essays connecting the classical kinetic theory with 20th century topics such as indeterminism and interatomic forces, there is an extensive international bibliography of historical commentaries on kinetic theory, thermodynamics, etc. published in the past four decades. The book will be useful to historians of science who need primary and secondary sources to be conveniently available for their own research and interpretation, along with the bibliography which makes it easier to learn what other historians have already done on this subject.

This book, which studies the links between mathematics and philosophy, highlights a reversal. Initially, the (Greek) philosophers were also mathematicians (geometers). Their vision of the world stemmed from their research in this field (rational and irrational numbers, problem of duplicating the cube, trisection of the angle...). Subsequently, mathematicians freed themselves from philosophy (with Analysis, differential Calculus, Algebra, Topology, etc.), but their researches continued to inspire philosophers (Descartes, Leibniz, Hegel, Husserl, etc.). However, from a certain level of complexity, the mathematicians themselves became philosophers (a movement that begins with Wronsky and Clifford, and continues until Grothendieck).
