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.

1 The Need for a New Theory. The following concepts of classical physics are necessary to understand the reason for the necessity of special relativity. [Kin] Rules of kinematics. [N3] Newton’s three laws of motion. [PGR] Principle of Galilean Relativity. [Max] Maxwell’s Theory of Electromagnetism.
(Very) basic introduction to special relativity. Math 3560 Groups and symmetry, Fall 2014. Raul Gomez. Figure : Isaac Newton. Law of inertia An object either is at rest or moves at a constant velocity, unless acted upon by an external force.
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.
Writing a new book on the classic subject of Special Relativity, on which numerous important physicists have contributed and many books have already been written, can be like adding another epicycle to the Ptolemaic cosmology.
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
Special Relativity. Although Newtonian mechanics gives an excellent description of Nature, it is not uni-versally valid. When we reach extreme conditions — the very small, the very heavy or the very fast — the Newtonian Universe that we’re used to needs replacing.
