Based on a series of university lectures on nonrelativistic quantum mechanics, this textbook covers a wide range of topics, from the birth of quantum mechanics to the fine-structure levels of heavy atoms. The author sets out from the crisis in classical physics and explores the seminal ideas of Einstein, Bohr, and de Broglie and their vital importance for the development of quantum mechanics. There follows a bottom-up presentation of the postulates of quantum mechanics through real experiments (such as those of neutron interferometry), with consideration of their most important consequences, including applications in the field of atomic physics. A final chapter is devoted to the paradoxes of quantum mechanics, and particularly those aspects that are still open and hotly debated, to end up with a mention to Bell's theorem and Aspect's experiments. In presenting the principles of quantum mechanics in an inductive way, this book has already proved very popular with students in its Italianlanguage version.It complements the exercises and solutions book "Problems in Quantum Mechanics", by E. d'Emilio, L.E. Picasso (Springer). "The book offers a good overview on quantum mechanics. Its style is fresh and exact. The explanations are often original, at least in the style. Some material like, for instance, om degeneracy and spatial inversion cannot be found easily in this form in other monographs. One gets the feeling that all this comes directly from the author's experience in teaching and thoughtful examination of the subject." (Marek Nowakowski, zbMATH, Vol. 1365.81002, 2017)
