Map Puzzles are downloadable and must be run on Windows. They challenge users to piece together the States of the United States or the countries of the world's continents, depending on the puzzle used. Interactive Maps allow users to move their cursor over a basic regional map. As the cursor hits each country, its name appears. The page a
Roman Numerals
This website provides an overview of the Principles of Roman numerals as well as a history of Roman numerals, which dates back to 1st millennium BC when they were used by Romans to record numbers in stone, art and coins. Some pictures in the gallery highlight the ways in which Roman Numerals are used today, such as on watch and clock faces. The authors point out that Roman numerals have a classic style and are less functional than the Arabic (decimal) numbers ( 0 to 9 ) which were introduced int
Datasheet Locator
With so many electronic components on the market today, it is often difficult to find datasheets with specifications and properties for a particular part. Rather than scouring the Internet for manufacturer's Web sites, Datasheet Locator has links to all the information you will need in one centralized location. The list of manufacturers currently numbers over 700. By directly connecting to the manufacturer's Web site, the information will always be up-to-date. Many of the companies allow searchi
Digital Signal Processing Tools
A collection of seven Java applets and associated tutorials are available on this site from the Signals and Systems Group at the University of Edinburgh. The tools illustrate various concepts of digital signal processing, like convolution, correlation, the Fourier transform, and discrete-time applications of each. Seven other applets that demonstrate more advanced concepts are also available, but no documentation or explanation accompanies them. A few conference publications and reports related
TranStats: The Intermodal Transportation Database
Provided by the US Bureau of Transportation Statistics, this site for researchers and analysts, which is aimed at providing "one stop shopping" for transportation data, allows users to search over 100 databases, download data, complete online statistics, and view online maps pertaining to data.

Although a newer browser
Australian Biological Resources Study: Flora Online
The Australian Biological Resources Study (ABRS) provides a bounty of biological and taxonomic information regarding Australian plant and fungi species. Acting as a clearinghouse for online information about plants and fungi, ABRS connects to such resources as the Flora of Australia Online, Checklist of Australian Lichens, Interactive Catalogue of Australian Fungi, Census of Freshwater Algae in Australia, and the Australian Plant Name Index. The site also provides a collection of glossaries that
DOE Pulse: Science and Technology Highlights from the DOE National Laboratories
The Department of Energies DOE Pulse bimonthly publication highlights work being done at the Department of Energy's national laboratories, which "house world-class facilities where more than 30,000 scientists and engineers perform cutting-edge research spanning DOE's science, energy, National security and environmental quality missions." Pulse provides insight into current research highlights, updates on collaborations among laboratories, and profiles of individual researchers. The latest issue,
World AIDS Day 2004
From the Joint United Nations Programme on HIV/AIDS, this website provides information and images related to Worlds AIDS Day 2004.

Capsule Pipelines
Capsule pipelines are a kind of tube transportation that uses hydraulics or pneumatics as a means of propulsion. This topic is somewhat ambiguous, because capsule pipelines are not widely used and several definitions exist. This site attempts to clarify what they are and explains their potential as a viable, or even superior, form of transportation. It briefly gives some history of capsule pipeline use and describes how they can be used in modern society. An overview of the technology that drive
An Overview of Cryptography
Gary Kessler, a computer networking professor at Champlain College, is the author of this online introduction to cryptography. The material covers three main types of encryption and their applications, trust models, cryptographic algorithms, and much more. One of the most common areas that employs encryption techniques is the Internet, where it allows users to safely transmit private information (e.g, credit card numbers, financial information). These concepts are discussed in detail, with speci
