I have commented before about how limited the living science literature field really is. If you want a nature story, or a biography you're in luck, but beyond that you will have trouble. That's why I like to feature good living science literature here.
Interestingly, while discussing this topic on Julie's Living Math Forum Yahoo group, she noted how hard it was to find any biographies of mathematicians. It seems math is full of concept readers, where science is lacking, and science is full of biographies, where math is lacking. Both, of course, have their share of text books.
While I am not giving up on science literature by any means, I have discovered that it is much easier to find wonderful science multimedia and web sites than literature. I have mentioned some of them here, and will continue to do so.
A related topic came up on the MEP board in the context of being unable to advance in science because of a lag in math. Living science multimedia is one good way to continue learning science without the math intensity of a science curriculum.
