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.
The general theory of relativity, together with the necessary parts of the theory of invariants, is dealt with in the author’s book Die Grundlagen der allgemeinen Relativitätstheorie (The Foundations of the General Theory of Relativity) — Joh. Ambr. Barth, 1916; this book assumes some familiarity with the special theory of relativity. v
As an introduction, special relativity is the study of high velocities, those close to the speed of light. Special relativity is based on two fundamental principles; the constancy of the speed of light and the universality of the laws of physics, which lead to the ideas of spacetime and 4-vectors.
Theory Of Relativity For Dummies What Is Relativity? Jeffrey Bennett,2014-03-04 A renowned astrophysicist s approachable introduction to Albert Einstein s theory of relativity and its application in our daily lives It is commonly assumed that if the Sun suddenly turned into a black
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.
The theory of relativity reveals the speed of light as the cosmic speed limit, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: E = mc2.
