The Internet is rich with science and technology-related sites, and over the past five years, we at Scientific have looked at an awful lot of themwhether in search of a site to review or one to simply help us understand a subject we're covering. Universities, individual educators, companies and nonprofit organizations alike provide a remarkable range of knowledge online, from basic tutorials to highly specialized papers. And in fact, there is so much information available that it's sometimes hard to zero in on what you need or to find buried gems without hours of distraction.

That said, we've decided to acknowledge our very favorite Web sitesfive each in 10 subject areaswith the Scientific Sci/Tech Web Award. It is an eclectic mixfrom the practical to the academic to the downright silly. Among this year's winners are sites that decode computer acronyms, explain group theory, unravel the genome, track chemistry in cartoons, and feature Britney Spears and superconductors in the same breath. Some are all-time classics, others not. But to our minds, they are among the Web's greatest hits. We hope you enjoy them as much as we do. If you'd like to nominate one of your favorites that isn't on the list for a future award, send us the URL. The Editors
