Who else here has this? What others of his works have you read?

I picked it up a couple of weeks ago. I'm still on the Class I Impossibilities, but it's pretty interesting stuff.
For those who don't know about it, it covers ways that Sci-Fi technologies, which we consider impossible, could potentially become possible in a more advanced society. One such example is making a Death Star cannon by tracking the lifeline and motion of a nearby star, then forcing it to rotate just before it dies and becomes a hypernova. Point it at the target, then watch it go. We have no way to do it now, but there's no law of physics saying that it's absolutely impossible. We know the life phases of stars, and no physical object is absolutely immovable. That kind of technology is atleast thousands of years off though.
