From the site: The Galileo Project is a source of information on the life and work of Galileo Galilei (1564-1642). Our aim is to provide hypertextual information about Galileo and the science of his time to viewers of all ages and levels of expertise. What you read and see here is a beginning — we will continue to add and update information as it becomes available. We solicit contributions from our colleagues in the history of science and comments on how we can improve the project from everyone, particularly suggestions on how to make this tool more useful in primary and secondary education.
