The book presents a concise course on theory of gravity. In spite of its limited size of only 116 pages, it covers the main theoretical notions and experimental phenomena. The author does it in a quite instructive way emphasizing underlying physics. Particularly impressive in this respect are chapters on observable effects, spin interaction, gravitational waves and black holes. The book's comparative analysis of radiation of gravitational waves by ultrarelativistic particles versus synchrotron radiation serves, in my view, as a best example.
I enthusiastically recommend the book, both to students who have just started studying the field as well as to established researchers.
