Anne Galloway provided some interesting links on"Drexlerian dreams and other politics of science".
Some weeks ago, I subscribed Howard Lovy's Nanobot with Bloglines. Interesting reads, excellent coverage of the nano-world. Just for records, I stumbled on this field because of my son's declaration that he wanted to study nanotechnology when he goes to university in 4 years time. At about the same time, a Thai friend recommended the book "As the Future Catches You: How Genomics & Other Forces Are Changing Your Life, Work, Health & Wealth" by Juan Enriquez showing me his "Thai!" version of the book. Digging in, I found that I had to check out the incredulous things this guy was saying. That took me to "Nanocosm" by William Illsey Atkinson. That was followed by a read of this very interesting: Atkinson-Phoenix Nanotech Debate With that I was convinced that I'd have to follow this microcosm.
