I would post this only on my video blog, but it was cool enough I'm including it here as well. I've only ever taken one biology class in my life, but I remember that it was fascinating stuff if you can get past the learning curve for the stuff you need to understand to be able to appreciate the intricacy of microbiology. But David explains it much better than I do and makes some excellent points about the nature of education. The images are great, but the video is mind-blowing.
