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 t'=t√ 1− v2 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.
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.
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.
This course will introduce you to the concepts behind special relativity including, but not limited to, length contraction, time dilation, the Lorentz transformation, relativistic kinematics, Doppler shifts, and even so-called “paradoxes.”
25 Μαΐ 2020 · The Special Theory of Relativity aims to established a link between space and time. In classical physics, space and time are separate and they are absolute, so they are the same in all...
The diagrams guide the reader, step-by-step, from the basics of relativity to advanced topics including the addition of velocities, Lorentz contraction, time dilation, twin paradox, Doppler shift, and Einstein’s famous equation E = mc2.
