Cassing W. Theoretical Physics Compact III. Quantum Mechanics 2025

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 clearly illustrated in diagrams. The required mathematics is derived in a physical context and explained transparently.
