Every year the editors at Scientific American give their best-of-the-web awards. Here they are for this year; 50 different sites in the areas/fields of anthopology & paleontology, astronomy, biology, chemistry, earth & environment, engineering & technology, great minds, health & medicine, physics and science for kids. I particularly liked the Rube Goldberg and the IEEE Virtual Museum sites in the eng & tech area. By the way, I hate it when math & computing get short shrift in these things. Math and computer science are distinct from both the physical & life sciences and from engineering and technology. With this kind of subject classification scheme, they just get left out.
