If you look over to The Left you'll find that I've added three science related sites to the 'skeptical' area. These are all recommended by James Randi and I've found some very interesting topics on all of them. Of course, I'll be the first to admit that Science was not my best subject back in school, although I generally enjoyed it.
Many of the essays on these sites are way above my head and level of understanding, but they all examine some of the myths, preconceptions and misunderstandings the general public has on such matters.
It doesn't hurt to get a 'second opinion' on things before you except anything at face value.
