Seventeen seminal papers, published from 1917 to 1926, develop and formulate modern quantum theory. Contributors include many of the leading physicists of the early 20th century: Einstein, Ehrenfest, Bohr, Born, Van Vleck, Heisenberg, Dirac, Pauli, and Jordan. The editor, a distinguished Dutch mathematician, provides a 59-page historical introduction. Reprint of the 1968 Dover edition.
Here's a sample of other books in this Dover category
Lectures on Quantum Mechanics by Paul A. M. Dirac Four concise, brilliant lectures on mathematical methods in quantum mechanics from Nobel Prize-winning quantum pioneer build on idea of visualizing quantum theory through the use of classical mechanics.
Quantum Mechanics by Albert Messiah Subjects include formalism and its interpretation, analysis of simple systems, symmetries and invariance, methods of approximation, elements of relativistic quantum mechanics, much more. "Strongly recommended." — American Journal of Physics.
Applications of Group Theory in Quantum Mechanics by M. I. Petrashen, J. L. Trifonov This advanced text explores the theory of groups and their matrix representations. The main focus rests upon point and space groups, with applications to electronic and vibrational states. 1969 edition.
