Beschreibungen

A new title in the Manchester Physics Series, this introductory text emphasises physical principles behind classical mechanics and relativity. It assumes little in the way of prior knowledge, introducing relevant mathematics and carefully developing it within a physics context. Designed to provide a logical development of the subject, the book is divided into four sections, introductory material on dynamics, and special relativity, which is then followed by more advanced coverage of dynamics and special relativity. Each chapter includes problems ranging in difficulty from simple to challenging with solutions for solving problems. <ul type="disc"> <li>Includes solutions for solving problems</li> <li>Numerous worked examples included throughout the book</li> <li>Mathematics is carefully explained and developed within a physics environment</li> <li>Sensitive to topics that can appear daunting or confusing</li> </ul>

‘<i>Dynamics and Relativity</i> by Forshaw and Smith was the ideal book for the upper level course Physics from Newton to Einstein at Yale since it was thoroughly modern and extremely lucid. Its most admirable features are the countless solved examples that made it ideal for self-study and a very detailed and lucid introduction to relativity.’<br /> — <b>Ramamurti Shankar</b>, John Randolph Huffman Professor of Physics, Professor of Applied Physics, Yale University
