Volume 1 of this course of theoretical physics deals with the fundamental laws of physics. The text lucidly presents for students and workers in theoretical physics the fundamental principles underlying the findings of experimental physics. It gives a unified presentation of classical mechanics, electrodynamics, and quantum mechanics and provides an excellent foundation for the study of more advanced topics in atomic, molecular, and solid-state physics. Fundamental laws can be read by students who have had courses in introductory physics, electricity, and magnetism.Alexander S. Kompaneyets (1914-1974)Professor Alexander Solomonovich Kompaneyets was a leading Soviet theoretical physicist from 1946 Until his untimely death he worked at the Institute of Chemical Physics of the USSR Academy of Sciences, contributing, among other things, to the development of nuclear energy in the Soviet Union in all its aspects.The book was translated from the Russian by V. Talmy and was published by Mir in 1978.
