With the aim of preparing students to read the works of Galileo Galilei, Albert van Helden, a historian at Rice University, and Elizabeth Burr, the university’s electronic text and images librarian, collaborated to produce the Galileo Project. The illustrated Web site offers information on the life and work of Galileo (1564–1642) and the science of his time.

In great and extensive detail, Doug Goff of the University of Guelph in Ontario, Canada, describes the history and science of Ice Cream. This much-loved food product, points out Goff on one of the site’s pages, is both an emulsion and a foam whose melting properties are influenced in part by the stability of colloidal particles known as casein micelles.

The Web abounds with sites that contain brief physics-related quotations. But in Garth’s Eclectic Collection of Physics-Related Quotations you’ll find a collection of long extracts from several science fiction novels, each related to an aspect of physics. The collection’s compiler, Garth Huber, is a particle physicist at the University of Regina in Saskatchewan, Canada.
