The Theory of Relativity and Applications: A Simple Introduction

This paper will provide a brief overview of the theory of relativity by looking at its two parts: special relativity and general relativity. It will omit most of the complex mathematics involved in order to focus on providing a more conceptual understanding. However, some simplified equations will be introduced to illustrate various aspects of the theory. Some of the experiments and scientific observations that support the theory as well as some of the scientific advances that emerged from the theory will also be discussed. Following the overview of the theory of relativity will be some of its applications in past and modern technologies. These applications will include cathode ray tube televisions, radar guns, the global positioning system and electron beam machining. After reading this paper, the reader should have gained a basic conceptual understanding of Einstein’s theory of relativity and an introduction to a few of its vast applications in technology.
