This document provides an introduction to special relativity. It discusses how special relativity was developed by Einstein in 1905 to explain experimental issues involving light and electromagnetism.
The special theory of relativity for dummies. If an object moves in relation to a (non-accelerating) observer, Einstein has taught us that the time of the object t’ differs from the time t of the observer, and in such a way that. v2. t '=t c2. Einstein deduced this by saying that the speed of light is the same for everyone and everything.

From reading this article, you will learn: The underlying reasoning behind what general relativity is all about; why we use tensors, how and why gravity has something to do with spacetime curvature as well as what the actual equations of general relativity really tell us in an intuitive sense.
In this article I plan on going over the fundamental principles of special relativity, both conceptually and intuitively, but also through the mathematics and equations behind the theory. First, I’ll explain the basic concepts that special relativity is based on as intuitively as possible.
1 Introduction. General relativity, and its application to cosmological models such as in ation, is a remark-ably beautiful and elegant theory. Yet newcomers to the eld often face at least three types of challenges: conceptual, mathematical, and notational.
