Understanding Physics

The physical universe has always been of great interest to mankind, and as we continue to develop an understanding of the world around us, there will always be a single set of rules that have come to be called Laws of Nature, which explain the behaviour of our physical environment. With this in mind, this second edition of Understanding Physics introduces 20th Century topics at an earlier stage than is usually found in introductory textbooks and these are integrated with more 'classical' material from which they have evolved. Understanding Physics emphasizes, in a fully rigorous manner, the essential unity of physics. In twenty-two chapters all fundamental concepts of physics, from classical building towards more specialised subjects, are presented. Among the many topics covered are: * Dynamics * Force fields * Relative Motion and Special Relativity * Thermal physics * Introduction to quantum mechanics * Electric Currents and Fields * Optics * Atom Physics * Nuclear physics, particle physics and astrophysics Throughout the text references are given to sources where more detailed discussions of particular topics or applications may be found, and worked examples and problems are presented at the end of each chapter. Understanding Physics is written primarily for students who are taking their first course in physics at university level. While it is anticipated that many readers will have some previous knowledge of physics or of general science, each topic is introduced from first principles so that the text is suitable for students without any prior background in physics.

It is well balanced, it is explanatory and it has an interesting integrated structure." --Dr Leif Karlsson, Uppsala University, Sweden
