Kimball's Biology Pages
Kimball's Biology Pages (first reviewed in the May 9, 1997 Scout Report) is an online biology textbook created and maintained by Dr. John W. Kimball, a veteran biology educator and retired Harvard professor. Dr. Kimball believes that the hypertext format is especially well suited for biological study because its nodal structure better approximates the relationships between biological subjects than a linearly structured textbook. In addition, a hypertext allows for more timely updates concerning

Design of a Primitive Nanofactory
This 86-page paper, published in October 2003, was written by the Director of Research at the Center for Responsible Nanotechnology. He proposes "an architecture for combining large numbers of programmable mechanochemical fabricators into a manufacturing system, or nanofactory, capable of producing a wide range of human-scale products." Rather than calling for the development of entirely new technologies, the author attempts to describe a system that can be built with current engineering practic
Dealing with Waste: The Nuclear Debate
Developed by the Industry Supports Education initiative (ISE), this website allows teenagers to take part in an online debate about how to cope with nuclear waste and whether and how nuclear power should be used in the future. During the debate, the user has a discussion with a virtual devil's advocate (DA). Visitors can either take the role of being in favor of nuclear power or against nuclear power. After the DA makes a statement, the user selects a response that most closely matches his or he
Rewind, Repair, Replay: Three R's to Dependability
One of the most important features in current software applications is the undo command, which allows users to revert to previous states in their documents. A relatively unexplored concept involves system undo, a method of restoring settings in a system that were accidentally changed by the operator. This research paper discusses "a model of undo that matches the needs of human error recovery and retroactive repair." The authors begin by explaining the growing importance of such a mechanism and
A Calculus Review
