RELATIVITY

Along with quantum mechanics
in the 1920s, Einstein’s Special Theory of Relativity (1905) and General
Theory of Relativity (1916) stand as the supreme achievements of
twentieth-century physics.In simplest terms, the theory of Relativity is an
approach to the measurement and study of space and time. The theory assumes
that findings are based upon the relation of the frame of reference to the
objects measured. The Special Theory of Relativity is primarily concerned
with electric and magnetic phenomena. The General Theory focuses on
gravity—not as a force as Newton postulated—but as a curved field in the
space-time continuum, created by the presence of mass.Redesigned to present
an easier reading, Relativity includes both explanatory illustrations and mathematical
derivations of Einstein’s theories. This book brings out the great
scientist’s remarkable ability to penetrate directly into the heart of the
subject and yet remain lucid and accessible.
