Drawing with the Hand in Free Space
Leonardo, a journal that focuses on applications of science and technology in art, included this paper in its second-to-last issue of 2002. The author discusses a fascinating method of creating three dimensional shapes in a semi-immersive virtual environment. Developed at Caltech, the technique tracks the motion of a user's hand, which is fitted with a special type of glove. With the help of an eyepiece viewing device, the user can see the corresponding surface drawing floating in midair. Severa
Air and Space Magazine: How Things Work: Series List
The Air and Space Magazine is a publication of the Smithsonian National Air and Space Museum. This special series of the magazine provides insight into various aspects of aerospace principles and technology. Three articles in this section can be accessed, despite the listing of all seven. First is an overview of winglets on airplanes, describing their purpose and how they increase performance. The second article looks at "devices an aerobatic airplane uses to defy gravity." Lastly, ejection seat
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
Material World Modules
The Materials World Program is an educational program created at Northwestern University intended to teach kids about science, math, and social issues by letting them investigate the objects that surround them in their everyday lives. While traditional science teaching divides the sciences into various disciplines, each studied separately, this program shows students that science is more than a set of techniques as "students using MWM learn how principles of chemistry, physics, and mathematics r
What is Climate Change?
This site is offered by Canada's Natural Resources Department. The main page describes the basics of the phenomenon, while the links tell about the impact of climate change on health and safety, communities, land resources, water resources, and coastal regions. Although specific to Canadian regions, the site will give visitors from all over a good introduction to the potential problems of global warming.
Science North: Learn and Play
Science North Museum is self-described as creating high quality science education and entertainment experiences for its visitors. The Learn and Play portion of the accompanying Web site contains a Cool Science link with a wide variety of activities including an interactive stargazer and solar system, science quizzes, a reflex tester, a geology exploration activity, and more. Other links on the Learn and Play page include descriptions and movies, additional recommended science links, and Web cams
Project INTERMATH
Project INTERMATH is an effort to reform undergraduate mathematics and related disciplines through the "use of Interdisciplinary Lively Applications Projects." This involves changing the traditional way that math is taught by moving to a more integrated and applied science. The material presented on the project's Web site reflects this approach. Of particular interest are the Products and Topics sections. The Products section has many specific scenarios that cover multiple areas of mathematics a
Smart Base Isolation Systems
Published in the October 2002 issue of the Journal of Engineering Mechanics, this research paper proposes a novel method of seismic base isolation. This technique is used to mitigate "the effects of an earthquake by essentially isolating the structure and its contents from potentially dangerous ground motion." The authors compare their method to several established base isolation strategies by simulating each under varying conditions for historical earthquakes. They show that the derived system

Historical articles and list of frequently asked questions are given on the site, as well as many transcripts of int
Hydroelectric Dams
Although hydroelectric power represents a relatively small portion of the world's energy resources, it is still an important commodity with great potential. To harness hydropower, civil engineers must design dams that convert the kinetic energy of water into electricity.The fundamentals of general-use dams are discussed on the home page of the US Society on Dams (1). Besides providing brief background information, there are a few examples of the benefits of dams to society. For a much more techn

Users may view images by category or click through the entire set in sequence. The photographs
Tales from the Underground
Chicago's Museum of Science and Industry Web site offers a very interesting interactive activity called Tales from the Underground. Kids get to explore an interactive map of Chicago neighborhoods to view the results of soil samples that were taken to determine the amounts of various pollutants they contain. Students are then able to conduct their own experiments (with help from their teacher or parent) to learn about the health of soils where they live. The site contains a wealth of additional a
