Space And Time In The Microworld | D. I. Blokhintsev

In comprehending the physical content of dynamic variables which have geometric meaning, for example, the space-time partic1e coor- dinates x, y, z, t it is often necessary to have recourse to gedanken experiments which, although not feasible in practice, can nevertheless be compatible with the basic principles of geometry and quantum mechanics. In a desert sea of abstract constructions there is a stiIl larger distance between macroscopic concepts of space-time and the way of em- ploying the coordinates x, y, z and t in relativistic quantum field theory.
The present monograph is based to agreat extent on the author's publications at different times. A large number of papers have been prepared jointly with his young colleagues at the Laboratory of Theoret- ical Physics at Dubna, B.M.Barbashov, N.A.Chernikov, G.I.Kolerov, G. V. Efimov and V. G. Kadyshevsky. The author was very glad to take the opportunity ofreflecting in this monograph some oftheir original in- vestigations. The author is very grateful to his colleagues for useful dis- cussions which have greatly contributed to clarifying many controversial questions. The author is especially grateful to M. A. Markov and B. M. Barbashov for their invaluable advice and comments and for fultilling the task of critically reading the manuscript, and to G. 1. Kolerov for his assistance in preparing it.
