Theoretical Concepts in Physics (3版)

In this original and integrated approach to theoretical reasoning in physics, Malcolm Longair illuminates the subject from the perspective of real physics as practised by research scientists. Concentrating on the basic insights, attitudes and techniques that are the tools of the modern physicist, this approach conveys the intellectual excitement and beauty of the subject. Through a series of seven case studies, an undergraduate course in classical physics and the discovery of quanta are reviewed from the point of the view of how the great discoveries and changes of perspective came about. This approach illuminates the intellectual struggles needed to attain understanding of some of the most difficult concepts in physics. Longair's highly acclaimed text has been fully revised and includes new studies on the physics of fluids, Maxwell's great paper on equations for the electromagnetic field and problems of contemporary cosmology and the very early universe. A unique book in the physics landscape emphasising the interaction between experiment and theory and giving the theoretical background behind some of the most important concepts in modern physics An ideal supplement to physics courses at the final-year undergraduate or starting graduate level, developing broad connections and explaining the historical development of key topics Fully revised with the addition of three new chapters covering Maxwell's dynamical theory of the electromagnetic field; the motion of fluids; and dark matter, dark energy and the inflationary paradigm in cosmology A companion volume, Quantum Concepts in Physics, extends the discussions focusing on the development of quantum mechanics
