I don't want to hijack this thread, but a while ago I posted an Ask HN requesting introductory books to nanotech -> https://news.ycombinator.com/item?id=18059301 https://news.ycombinator.com/item?id=18059301. Never heard of Engines of Creation, but it looks like what I'm looking for (just ordered from Amazon). Apart from Engines of Creation are there any good intro texts?
