A Place in Space
The students will use a “real” 3D coordinate system. They will have 3 axes at right angles, and a plane (the XY plane) that will be able to slide up and down the Z axis. The students will then be given several coordinates and asked to find these points in space. They will also be asked to find the coordinates of the 8 corners of a box with given dimensions.

Created by Forum One Communications and funded by the Corporation for Public Broadcasting, Backyard Jungle is a kid-friendly Web site where members can upload photos, drawings, and descriptions of their own backyard or other natural area to share with an online community. Membership registration is straightforward and free of charge. While Backyard Jungle does not include any formal lesson plans or educational activities, it offers kids a fun incentive to explore and communicate about their natu
Sometimes learning or at least sparking an interest in a subject can be accomplished through pictures. The Geoscapes Photography Web site by Emeritus Professor of Geology John A. Karachewski contains spectacular photos of various geologic formations from the western US. By clicking on the main gallery link, students can choose from various locations such as northern California, Point Reyes National Seashore, Colorado, and Utah. Each link then contains the photographs and simple descriptions of t
Protecting Applications against Malice Using Adaptive Middleware
Security in distributed computing systems is a very important area of research, especially as malicious behavior is a growing cause of concern for businesses and organizations. This paper addresses an emerging method of maintaining security in untrustworthy environments. Until recently, the operating system was the only means of protecting data; the authors discuss a more elaborate technique of using middleware as a second level of security. "When integrated effectively, this multi-level approac
DesignNotes.com: Design Archives
This novel site gives examples of circuits for a wide range of applications. It is suitable for people looking for specific instructions for a predetermined project or for anyone with an electronics hobby.

Several categories are shown, including audio, motor control, and digital signal processing. Alt
According to its author, this site was created to provide the public with an "'upper secondary' math tutorial." It is immediately apparent that this can include many different subject areas and, indeed, the site addresses topics ranging from trigonometry to linear algebra to calculus. Each concept is introduced with clear, concise explanations and illustrative figures, and several sample problems are given with accompanying solutions. The only minor fault with this site is the use of plain text
