Textbook in PDF format This book, together with the three other volumes, offers a clear and comprehensive approach to theoretical physics for the entire Bachelor's program. Theoretical derivations are linked with characteristic examples, their solutions, typical applications, and are clearly illustrated in figures. The required mathematics is derived within a physical context and transparently explained. Contents: Statistical Ensembles – Identical Particles – Concept of the Statistical Ensemble – Statistical Definition of Entropy – Statistical Ensembles in Equilibrium – Independent Identical Particles – Statistical Mechanics and Thermodynamics – Small Deviations from Equilibrium – The Ideal Fermi Gas – The Ideal Bose Gas – Real Gases – Magnetic and Electric Properties of Matter – Kinetic Theories
