That said, we’ve decided to acknowledge our very favorite Web sites—five each in 10 subject areas—with the Scientific American.com Sci/Tech Web Award. It is an eclectic mix—from 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. —Scientific American
