The Riddle of Gravitation - Revised and Updated Edition

More about the book

In this thought-provoking work aimed at the general reader, a distinguished physicist presents a fresh, nonmathematical overview of the conceptual foundations of both Newton's and Einstein's theories of gravitation. The first part primarily focuses on Einstein's special theory of relativity, covering the evolution from Newtonian physics to Einstein's revelations about the relativity of time and space, culminating in Hermann Minkowski's integration of these concepts into a four-dimensional framework. The second part delves into general relativity, positing that gravity influences the curvature of space and time, allowing for a geometric understanding of gravitational phenomena. The third section explores recent advancements, such as the quest for gravitational waves, quantum gravity, and particle motion, among other topics. Five appendices provide mathematical derivations for readers seeking a more technical perspective. In this new edition, Professor Bergmann has included updated discussions on gravitational radiation detectors, contemporary cosmological challenges, and the implications of gravitational field singularities. This engaging exploration of theoretical physics remains accessible to nonphysicists, making it an excellent resource for any curious layman interested in relativity theory and its connection to modern astronomical insights.
