Beneath the Foundations of Spacetime
Special relativity can be derived with moving rulers in such a way that the astonishing connection between space and time can be clearly understood.
Einstein Light
A multimedia tutorial on Special Relativity. The introductory level takes 10 minutes, but has links to over 40 explanatory pages giving greater depth and breadth.
Einstein, Nordström and the Early Demise of Scalar, Lorentz Covariant Theories of Gravitation
Conventional thinking says that all Lorentz covariant gravitation theories are unacceptable. 74 pages.
Henri Poincaré and Relativity Theory
Who created the theory of relativity? This reference identifies the substantial contributions made to relativity theory by the mathematician Henri Poincaré. 254 pages.
How Stuff Works: Special Relativity
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.
Poincaré and the Special Theory of Relativity
It is often not appreciated that it took many great minds to finally attain the point of view that is now called ‘the special theory of relativity’.
Relativistic contraction
Relativists consider it a very important exercise to have students decide how to measure the length of a rapidly moving object.
Special Relativity
A unit for an online relativity textbook explaining special relativistic mathematical physics.
Special relativity lecture notes
A standard introduction to special relativity where explanations are based on pictures called spacetime diagrams.
Special Relativity simulator
Warp is a program that illustrates the appearance of fast moving objects due to special relativity.
Synchronization Gauges and the Principles of Special Relativity
Synchronization functions set the mathematical clocks represented by the Lorentz transformation and resetting these clocks mathematically only produces a theory equivalent to speci…
The Twin Paradox in a Spatially Closed and Bounded Universe
Spatially compact spacetimes break global Lorentz invariance and define absolute inertial frames of reference.
Why No 'New Einstein'?
Followers of large well-supported research programs have lots of powerful senior scientists to promote their careers. People with the uncanny ability to ask new questions or recogn…
