Appropriately enough, the idea for the Web came from scientists—just as had the original idea for the Internet.
In 1989 Tim Bemers-Lee, a physicist at the European Particle Physics Laboratory (CERN), proposed the concept of the Web as a system for transferring ideas and research among scientists in the high- energy-physics community.
Berners-Lee’s original proposal defined a very simple implementation that used hypertext but did not include multimedia capabilities. Something very much like this was introduced on Steve Jobs’s NeXT computer system in 1990. The NeXT implementation allowed users to create, edit, view, and transmit hypertext documents over the Internet. The system was demonstrated for CERN committees and attendees at the Hypertext ‘91 conference.
In 1992 CERN began publicizing the World Wide Web (WWW) project and encouraging the development of Web servers at laboratories and academic institutions around the world. At the same time, CERN promoted the development of WWW clients (browsers) for a range of computer systems including X Windows (Unix), the Apple Macintosh, and PC/Windows. (Today, the two most popular and useful of these browsers are Netscape Communicate and Micorosfi Internet Explorer—both of which are available via free download on the Internet.)

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.”

The Internet. It seems so fundamental to our lives. Looking back over the last few—f n fact, very few—years, we wonder how we ever lived without its numerous, readily-available resources just as we wonder how we ever lived without desktop computers themselves, digital notebooks, and cellular phones.
Of course, most scientists have been on familiar terms with the Internet for quite some time. The fabled network of networks was, after all, first created by scientists themselves with scientists in mind. Up until a few years ago, the Internet was used almost exclusively by engineers, scientists, academics and students as a vehicle for sharing information and research. In 1985 the Internet boasted only 1,961 host computers and numbered its users in the tens of thousands. But as many scientists know only too well, the once-pristine electronic frontier of the Internet has now been overrun by new settlers. In fact, the Internet has doubled in size every ten months for the past ten years. Today the number of Internet users increases by a more than two million new logins each month.
Along with vast numbers of “lay” Internet users have come vast numbers of purveyors of all sorts of information: the new gold of the electronic frontier toward which so many settlers rush. Scientific information certainly continues to have its place in the newly settled territories of the Internet. And scientific resources continue to grow in number. However, scientific information on the Net no longer constitutes the majority share. Scientific information plays second fiddle to financial information, religious information, erotic information, political information, literary information, and so on.
On the “plus” side, the information resources of the Internet seem to increase at almost as fast a rate as do the number of Internet users. The steadily growing profusion of information options—including information options related to the sciences—is wonderful. It is also utterly confusing.
