Special Relativity

» E=mc² - An article from the Wikipedia encyclopedia. » 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. » Generalized Relativistic Velocity Addition with Spacetime Algebra - The general problem of relativistic addition of velocities – and the successive application of noncollinear Lorentz boosts – is addressed. [PDF] » Geometric Algebra for Physicists - This is chapter 1 of a book by Chris Doran and Anthony Lasenby on geometric algebra, which is the natural mathematics of spacetime. [PDF] » How Do You Add Velocities in Special Relativity? - Here is the formula for adding velocities in special relativity when motion occurs in a single direction. » 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. » Imaginary In All Directions - There is a preferred algebra of quaternions and complex numbers that is ideally suited to express the equations of special relativity and classical electrodynamics. [PDF] » Jim Doyle's Special Relativity Pages - A growing collection of pages on special relativity, including Special Relativity in under 15 Minutes! » Lorentz Contraction and Accelerated Systems - Lorentz contraction in systems undergoing constant proper acceleration is proven to be completely self-consistent in the context of special relativity. [PDF] » Nothing but 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. [PDF] » One More Derivation of the Lorentz Transformation - The theory of relativity is constructed from four general group-theoretical assumptions on the structure of space-time: These are homogeneity, isotropy, group structure and a causality condition. [PDF] » Quaternions in University-Level Physics Considering Special Relativity - The quaternions are an expansion of complex numbers and show close relations to numerous physically fundamental concepts (e.g. Pauli Matrices). [PDF] » Relatively Simple - Special Relativity made Relatively Simple offers information and experiments about special relativity. » Relativistic Contraction - Relativists consider it a very important exercise to have students decide how to measure the length of a rapidly moving object. » Relativistic Force Transformation - Formulas relating one and the same force in two inertial frames of reference are derived directly from the Lorentz transformation of space and time coordinates. [PDF] » Relativistic Kinematics - This is how special relativity is taught by Dr. David Morin at Harvard University. 72 pages. [PDF] » Relativity Tutorial - An introduction to relativity using space-time diagrams. » Santa at Nearly the Speed of Light - 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. » Space Measurements on a Rotating Platform - The age-old puzzling problem of Lorentz contraction on a rotating platform, i.e., Ehrenfest's paradox, is explained in its proper mathematical context. [PDF] » Special Relativity - Tutorial explains about the postulates, paradox, simulaneity, time dilation, Lorentz transformation constructions, spacetime wheel, and the Fitzgerald-Lorentz contraction. Page includes some animated illustrations. » Special Relativity Lecture Notes - A standard introduction to special relativity where explanations are based on pictures called spacetime diagrams. » Special Relativity and Maxwell Equations - A self-contained summary of the theory of special relativity is given, which provides the frame for classical electrodynamics. 26 pages. [PDF] » 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 special relativity in predicting empirical facts. 57 pages. [PDF] » The Axiomatization of Physics - Step 1: A Derivation of the Lorentz Transformation - The fundamental equations of special relativity are derived with only high school algebra and toy universes consisting of moving rulers. [PDF] » The Structure of Space-Time Transformations - This theorem by H. J. Borchers and G. C. Hegerfeldt proves that the constancy of light velocity alone implies the Lorentz group (up to dilatations). » The Twin Paradox in a Spatially Closed and Bounded Universe - Spatially compact spacetimes break global Lorentz invariance and define absolute inertial frames of reference. » Time Dilation - The gamma factor and time dilation can be derived using a very simple clock. » University Lectures on Special Relativity - Lecture notes on Special Relativity, prepared by J. D. Cresser, Department of Physics, Macquarie University. 44 pages. [PDF] » Wikipedia: Special Relativity - Online encyclopedia article.
