Special Relativity  

In General > s.a. minkowski spacetime; modified classical mechanics [relationship to Newtonian mechanics].
* Motivation: (E) If Galilean relativity is right, when I move at the speed of light I should see a static pattern, but Maxwell's equations do not admit such a solution!
* Postulates: (i) All inertial observers are equivalent (including laws of electromagnetism); (ii) The speed of light c is constant, independent of the motion of the observer (or the source) – inconsistent with Galilean physics; > s.a. lorentz symmetry.
* Particles / fields: Dynamical equations must be tensorial (Lorentz-covariant), a severe restriction on physical laws; > s.a. relativistic particles.
* Remark: Not all coordinate systems are allowed; Hilbert used 1 timelike and 3 spacelike coordinates; More recently, 4 null ones have also been used [@ Hilbert GN(17)].
blue bullet Particle-related concepts: see energy; force; momentum; particle models; special-relativistic kinematics.

Applications, Effects, Tests > s.a. causality violations; constants [speed of light]; electromagnetism.
* Constancy of c: Michelson-Morley experiment; Ether-drift experiments based on the Mössbauer effect; 2000, Independence of vsource confirmed to 1 × 10–20, with γ-rays from GRBs; 2001, improved Kennedy-Thorndike Tests on independence of vlab; 2002, Experiments by University of Konstanz and Düsseldorf checked isotropy of c to 1.7 parts in 1015 with optical cavities; Precise tests are motivated in part by some versions of string theory.
* Time dilation: High-speed electrons from certain radioactive decays, accelerated particles, cosmic rays and muons; Conceptually better than atomic clocks.
* Properties of materials: Special relativity shifts around the energy levels of electrons in gold atoms, causing the metal to absorb blue light, and thereby making reflected light appear more yellow.
