Quantum mechanics is the third part of the course of theoretical physics studied by students of the physical specialty. Quantum mechanics, together with special relativity and statistical physics, form the basis of modern natural science. That is why the future teacher of physics is obliged to thoroughly study this interesting and important science, which has not only educational, but also ideological significance. In this tutorial, the main part of the program material is presented in a summary, the main attention is paid to the disclosure of its physical content. The mathematical apparatus of quantum mechanics is set out in a previously published manual, so it is not included in this edition. There are also some questions that we think are overloaded with mathematical calculations and which can be found in any textbook on quantum mechanics. Not included in the manual and tasks, as we have released a special "tasker-workshop on quantum mechanics"
