Also, this is a great video. SCIENCE in action!
Lastly, if you're looking to read some semi-hard sci-fi that comes in big books about 4cm thick, I just finished a Richard Morgan book which I quite enjoyed. It started a bit slow, but developed into a pretty good cyberpunkish thriller. It turns out it's the third book in the series, but it was good enough on its own that I've gone out to get the first one. Although I note he's strictly following the Adjective-Noun school of book naming.
Speaking of naming, chapter 5 has a title now - Picking up the Pieces. Not that it really matters all that much, but having given the first four titles it only seemed fair.
