Some Cool Ways of Looking at the Special Theory of Relativity.
Special relativity was originally proposed by Albert Einstein in a paper published 26 September 1905 titled "On the Electrodynamics of Moving Bodies". The inconsistency of Newtonian mechanics with Maxwell's equations of electromagnetism and the lack of experimental confirmation for a hypothesized luminiferous aether led to the development of special relativity, which corrects mechanics to handle situations involving all motions and especially those at a significant fraction of the speed of light (known as relativistic velocities).
Today, special relativity is the most accurate model of motion at any speed when gravitational effects are negligible. Even so, the Newtonian mechanics model is still valid as a simple and high accuracy approximation at low velocities relative to the speed of light.
In this video I'll show you how to prove its two postulates using easy-to-understand real-world experiments, and how even the simplest understanding of quantum mechanics can be used to wrap your mind around why time must slow down the faster an object moves.
