SuperFast Guides
The SuperFast Guides are quick and easy summaries of relativity and related subjects.
Each one focuses on the main and most important points, with further information
available from the main E = mc

Explained website.
Einstein - A short biography of Albert Einstein
Special Relativity - How time changes due to speed
General Relativity - How time changes due to gravity
Time Dilation - Different time for different observers
Black Holes - How they form and what they are
The Twin Paradox - Twins ageing at different speeds
A selection of more detailed pages:
Solving the Equation A simple walk-through of the equation
