- Planetary Image Atlas
Provided by NASA's Jet Propulsion Lab and the Planetary Data System, this site is designed to eventually serve as a single interface
for searching, displaying, and downloading images and data from a number of planetary missions. In the meantime, the site acts as a portal to the older individual mission collections. These include Galileo, Mars Pathfinder, Viking Lander, Viking Orbiter, Magellan, and Clementine. The site and the data featured are meant primarily for scientists in related fields, but a number of images and mosaics that are available may interest non-specialists.
- NASA Science
- The Particle Adventure
This site "introduces the theory of fundamental particles and forces, called the Standard Model." Related links; charts and diagrams of the standard model; and a basic introduction to particle physics are also included. Also available in Spanish, French, Polish, and Slovene. From the Particle Data Group of Lawrence Berkeley National Laboratory.
- Inquiring Minds
An easily understood explanation of "elementary particles and forces in our universe." Included are Questions About Physics with answers from Fermilab's scientists; links to physics laboratories from around the world; a glossary and other related resources, photographs, live collisions, and more. Additionally, there is a timeline of the development of high-energy physics. From the Fermilab (Fermi National Accelerator Laboratory, operated under a contract with the United States Department of Energy).
- Stanford Linear Accelerator Center Virtual Visitor Center
Written for the layperson, this searchable site presents information about subatomic particle accelerators including diagrams of their different components, their history, applications, the method of detecting the particles, theories, cosmic rays, and experiments being conducted at the Center as well as Nobel Prize winners in Physics at the Center. Additionally, information about the Stanford Synchrotron Radiation Laboratory (SSRL) is available. Included are a glossary and photos.
- Fractals Links Page
Annotated links to sites about fractal theory, collections of fractals, download sites for fractal software, fractal music, and fractal newsgroups. Maintained by Ontario, California, Chaffey High School students.
- Fractals Theme Page
Annotated links to Web sites related to fractals, including explanations of what fractals are and software to make them. Provided by the Community Learning Network.
- Infinite Fractal Loop
A fractal art Web ring (interlinked, related Web sites) of over 100 sites. The site includes a definition of "fractal," a section on software available for creating fractals, and graphical and textual lists of the sites in the ring.
- Theater of Electricity
Explore the history of the Van de Graaff Generator, which "was originally used as a research tool in early atom-smashing and high energy X-ray experiments." The site also includes information about the generator's construction, with an animation of how it works and pictures of it producing sparks; of lightning and Benjamin Franklin and his kite; information and images of Tesla Coils; a discussion of lightning, including a safety quiz; resources for teachers; and a video and picture gallery. From the Museum of Science, Boston.
- Official String Theory
A well-done explanation of a complex theory in particle physics. Includes the basics of string theory, experiments testing string theory predictions, string theory and cosmology, and a timeline of string theory development. The String Theater presents a RealAudio colloquium by Professor John Schwarz. There are also Real Audio interviews with people involved in the research, a discussion forum, and related links.
- Chaos at Maryland
"Since the mid-1970s, the Chaos Group at Maryland has done extensive research in various areas of chaotic dynamics ranging from the theory of dimensions, fractal basin boundaries, chaotic scattering, controlling chaos, etc." In addition to research reports there is a chaos gallery; an extensive publications section with general references, online papers, abstracts, and The Chaos Database, a searchable database of more than 11,000 articles on nonlinear dynamics (CHAOSBIB); and a good list of links to other Web resources on chaotic behavior in systems. From the University of Maryland, College Park.
Journals and Databases
- Physical Review Focus
An online service from the American Physical Society (APS), Physical Review Focus publishes selective research papers from Physical Review Letters (PRL) to provide "educational value and intrinsic interest to non-specialists" and physicists. Each story is accompanied by a link to the research paper abstract in PRL while subscribers (membership is not free) to PRL online have access to the full-text article. In addition, links to Physical News Update and Physics News Preview from the American Institute of Physics are also provided. Users have access to articles published since March 1998.

A collection of articles exploring the physics of car racing. There is a FAQ.
- Traffic Waves: Physics for Bored Commuters
Ever find yourself stuck behind lines of traffic on the interstate, but when you get to the end of the slowdown there's nothing there? Now
you can find out how traffic phenomena like this occur at Traffic Waves, an interesting site created and maintained by William J. Beaty, an
electrical engineer in Seattle. As the site reveals, Beaty is not an expert in "traffic physics" but rather a commuter who has had plenty of time to observe traffic patterns and try different experiments. In addition to several essays on traffic patterns and experiments, the site features illustrations, animations, related links, and a FAQ. A fun site for anyone who spends too much time behind the wheel.
