The book presents computational practice for a wide range of problems from the quantum physics of single- and multi-particle systems. The text has the character of worked examples, which touch on a number of topics such as approximate methods in quantum mechanics, momentum or atomic structure and several more advanced examples motivated by more complex physical systems. It also contains a separate part summarizing the basic properties of solvable quantum systems.

For a number of examples, several variants of the solution are given, suggestions for extending the example or a separate deeper reflection of the results. Readers are also introduced to the physical consequences of the calculations performed, often accompanied by a picture or graph. It is a typical book for the evening. You will either fall asleep with it or find out in the morning that you forgot to go to bed at night. The book provides a wide range of answers to the life questions of particles, the universe, and physics teachers.
