They don't replace handbooks - they support handbooks because they can do things that handbooks can't do.They don't replace handbooks - they support handbooks because they can do things that handbooks can't do.They: (1) are interactive; you get immediate feedback. (2) can show objects in 3D by rotating them on the screen. (3) are dynamic; you see things happening right in front of you. (4) make use of virtual objects with which you can do experiments and teachers and parents can do demonstrations.

Einstein's theory of special relativity includes electricity and magnetism in a simple, logical extension of the relativity of Galileo and Newton. Its conclusions, including time dilation, length contraction, and E=mc2 have changed profoundly our ideas of time and space, matter and energy. These multimedia modules (click on menu above right) give a brief overview of relativity - they present the main ideas. Inevitably, you will have questions. So the related links (below) give more complete explanations, at levels with () or without mathematics ().
