Special relativity becomes simple and very convincing when the Lorentz transformation is derived, not from Einstein's principle of relativity, but only from Newton's first law of motion and the homogeneity of time.

A short overview of special relativity, filled with relativistic ray traced images. Explains relativistic effects using a theoretical spaceship.

Here is the formula for adding velocities in special relativity when motion occurs in a single direction.

The major principles of special relativity (SR) are discussed in an accessible way, via 5 segments, to help you understand the lingo and theories involved.

There is a preferred algebra of quaternions and complex numbers that is ideally suited to express the equations of special relativity and classical electrodynamics.

Individual photons, which tunnel through a quantum barrier, can apparently travel faster than light.

A growing collection of pages on special relativity, including Special Relativity in under 15 Minutes!

Lorentz contraction in systems undergoing constant proper acceleration is proven to be completely self-consistent in the context of special relativity.

There are many ways to derive the Lorentz transformation without invoking Einstein's constancy of light postulate. The path preferred in this paper restates a simple, established approach.

The quaternions are an expansion of complex numbers and show close relations to numerous physically fundamental concepts (e.g. Pauli Matrices).

Special Relativity made Relatively Simple offers information and experiments about special relativity.

Relativists consider it a very important exercise to have students decide how to measure the length of a rapidly moving object.

The discovery of special relativity was inevitable, given the momentous discoveries that preceded it.

An introduction to relativity using space-time diagrams.

An estimate of the speed and distances covered by Santa Claus on Christmas night. The physics is unassailable. The article is hosted on the Fermi National Accelerator Laboratory website.

The age-old puzzling problem of Lorentz contraction on a rotating platform, i.e., Ehrenfest's paradox, is explained in its proper mathematical context.

This is chapter two of Christoph Schiller's 1000 page walk through the whole of physics, from classical mechanics to relativity, electrodynamics, thermodynamics, quantum theory, nuclear physics and unification. 61 pages.
