Four concise, brilliant lectures on mathematical methods by the Nobel Laureate and quantum pioneer begin with an introduction to visualizing quantum theory through the use of classical mechanics. The remaining lectures build on that idea, examining the possibility of building a relativistic quantum theory on curved surfaces or flat surfaces.
Here's a sample of other books in this Dover category
The Physical Principles of the Quantum Theory by Werner Heisenberg Nobel Laureate discusses quantum theory, uncertainty, wave mechanics, work of Dirac, Schroedinger, Compton, Einstein, others. "An authoritative statement of Heisenberg's views on this aspect of the quantum theory." — Nature.
Methods of Quantum Field Theory in Statistical Physics by A. A. Abrikosov, L. P. Gorkov, I. E. Dzyaloshinski, Richard A. Silverman This comprehensive introduction to the many-body theory was written by three renowned physicists and acclaimed by American Scientist as "a classic text on field theoretic methods in statistical physics."
Primer of Quantum Mechanics by Marvin Chester Introductory text examines classical quantum bead on a track: state and representations; operator eigenvalues; harmonic oscillator and bound bead in a symmetric force field; bead in spherical shell. 1992 edition.
Sources of Quantum Mechanics by B. L. van der Waerden 17 seminal papers, published from 1917 to 1926, develop and formulate quantum theory. Contributors include Einstein, Bohr, Born, Van Vleck, Heisenberg, Dirac, Pauli, and Jordan. An introduction provides historical perspective.
