About the book author says: âI came to the decision to write this book having in mind that there was so much interesting in various areas of physics and astrophysics and yet many budding physicists and students were not aware of this and could hardly find out for themselves. So I decided to do something constructive in this way, to describe briefly some urgent problems of physics and astrophysics.â One of the reviewers of the book in Physics Today (July 1977) says following about the author: Ginzburg is a generalist whose encyclopedic reading and depth permit coverage of a variety of such novel, specialized material. He uses order-of-magnitude (nearly dimensional) formulas, sufficient to provide quantitative estimates. He appreciates the experimenterâs contribution. The book provides a model of how non-theorists can judge what realms of theory may be illuminated by work in a new range of photon and particle energy, how new technologies may be used to good effect. The book has three sections dealing with Macrophysics, Microphysics and Astrophysics and in the end is full of references for each of the fields. This book was translated from the Russian by Oleg Glebov and was first published by Mir in 1976 with a revised and enlarged edition in 1978. Link below is for 1978 print.
