With endorsements from both Scientific American and Science magazines, this website developed by The University of New South Wales is gaining currency among those interested in using the web for educational purposes. The basic mission of the Einstein Light site is to present a brief overview of Einstein’s theory of relativity and its relationship to the work done by Galileo and Newton. This of course means they must address such thorny topics as time dilation and length contraction. They do just that, with the assistance of two animated models, Zoe and Jasper. Throughout the various modules presented here, the two models provide the means by which the casual visitor can begin to understand these concepts. Visitors may also appreciate the fact that there are also a number of related links offered here for further edification. Some of the sections here include “Electricity and magnetism in a moving frame: what would you expect?” and “Is time dilation true?”. Overall, this is a well-designed site that will be of interest to those with a general interest in this subject and for educators as well.
