From the reviews: "Anyone who has taught a course of quantum mechanics knows the difficulty of providing practical examples which are within the mathematical competence of the students and can be completed in a reasonable time. In this book will be found 219 problems, together with their solutions, which will greatly extend the repertoire. (...) The first volume deals exclusively with one-body problems without spin. (...) In the second volume the problems cover a wider range and include illustrations of the introduction of spin, the interactions between two and three particles, quantum statistics and the Dirac relativistic equation with shorter sections on non-stationary problems and radiation theory. (...)" Nature, Sept. 10, 1971. "The student who can master these problems will have a good grasp of the practical applications of quantum theory and, therefore, of the basic concepts as well. I recommend the book unreservedly." The Australian Physicist, May 1972.
Siegfried Flügge was a German theoretical physicist who made contributions to nuclear physics, including articles important to the development of nuclear weapons. He worked in the German Uranverein (nuclear weapons project), 1939. From 1941 onward he was a lecturer at various German universities; he was also a visiting professor at U.S. universities between 1949 and 1953. From 1956 to 1984, he was editor of the 54-volume, prestigious Handbuch der Physik.
