## Description

Time and Space Weight and Inertia covers the relationship between time, space weight, and inertia using the principles of theory of relativity and chronogeometry.

This book is composed of 12 chapters, and begins with a brief overview of the fundamental aspects of space and time within events. The subsequent chapters deal with the chronogeometry of time and space, and the concept of the Lorentz transformations and pseudo-revolutions. These topics are followed by discussions on the dynamical relationships of metric and other tensors and a presentation of the equations of the theory of electrons. The remaining chapters describe the unique value of the acceleration in free fall, geodesic coordinates carried along in free fall, and the field equations, as well as the so-called curving of light rays.
This book will prove useful to physicists and mathematicians.
