The most popular aspect of the Internet is, of course, the World Wide Web. The “Web”—as it is familiarly called—provides access to virtually all those computers (servers) on the Internet that offer hypermediabased information and documentation.
Hypermedia is a technology that presents and relates information by using nonlinear, nonsequential links rather than linear sequences. (Less formally put, hypermedia and hypertext enable users to navigate both the World Wide Web and the documents on it with point-and-click ease. To navigate, one “clicks” on words, phrases, and icons in a document, which provide links that enable you to jump at will to a new location in the document, or even to a new document altogether.) In short, the Web is a uniquely intuitive and information-rich environment.
Additionally, the Web is hospitable to graphic images, photographs, audio, and even full-motion video. Thus the Web has a multimedia capability that is of great value to scientists and those interested in science. Astronomers can view full-color space images on-line. Oceanographers can access real-time “remote sensor” data from key oceanographic sites around the world 24 hours a day. Students of chaos theory on the East Coast can connect and watch fractal trees generate on a minicomputer in Los Angeles. And paleontologists can get audio and image clips of Stephen Jay Gould giving a series of lectures at Harvard.
An additional perk of Web technology is that the Web provides easy tools for inexpensive on-line publication. Combining global connectivity and individual empowerment, the Web enables anyone who has a computer and the proper Internet connection to become a multimedia publisher. With the right tools (most of them available as free downloads from sits highlighted in this book) and a little effort, you can easily translate scientific papers into electronic Web documents (also known as “pages” or “sites”) that the entire world can access. The same goes for reports. calls for papers, conference proceedings, announcements, course catalogs, etc. For more on this see the section later in this chapter entitled “A Few Web Fundamentals/ General Web Resources.”
