This 1947 volume is a landmark in the history of physics, representing the first Soviet publication of what was widely considered the finest textbook on relativity of its era. Written by Peter Bergmann (1915–2002), a close associate of Albert Einstein at the Institute for Advanced Study, the book was originally published in the USA in 1942. Its international prestige was cemented by Einstein’s own foreword, in which he famously declared: "This book presents the most complete and clear treatise on the theory of relativity that I have ever read."
The Russian edition holds unique scholarly value due to the involvement of Vitaly Ginzburg (1916–2009), a future Nobel Laureate and a giant of Soviet theoretical physics. Ginzburg not only edited the translation but also provided significant supplements that updated the text with recent developments in relativistic astrophysics and field theory. The book is divided into three parts: the Special Theory of Relativity, the General Theory, and Unified Field Theories—the latter being a subject on which Bergmann worked directly with Einstein.
Mathematically rigorous yet exceptionally lucid, Bergmann’s text avoids unnecessary complexity, focusing on the logical structure of Einstein's thought. It covers the tensor calculus necessary for understanding gravitation, the motion of particles in gravitational fields, and the cosmological implications of the theory. In the post-war USSR, this book served as the primary bridge for a new generation of Soviet physicists—including those involved in the nuclear and space programs—to master the intricacies of four-dimensional physics.
As a first edition from 1947, published by the Foreign Literature Publishing House (Inlit), this book is a significant bibliographical rarity. It captures a moment of high intellectual exchange between Western and Soviet science before the onset of the deepest Cold War isolation. For collectors of Einsteiniana, historians of theoretical physics, and bibliophiles of classic scientific texts, this "Ginzburg-edited Bergmann" is an essential cornerstone.
