I'm late. I'm late. I'm late ... but I finally managed to read more than 2 pages this morning.
I tried making a dent in this on the train home yesterday, but not really having slept the night before caught up with me and I pretty much slept all the way back home, then went straight to bed...
Anyway, I was a bit puzzled by the chapter set in Discworld as it wasn't clear, yet, where the science part was. That was my only concern, tho. Other than that, I loved the wizards and the squash court setting, and the way that Pratchett translated real concerns into bitingly satirical comedy.
The science that I was missing followed in the subsequent chapter. And lots of it. Much went over my head, but I appreciated that the authors deliberately left our formulae and tried to describe the concepts in "real words". I mean, even with that I was lost at Planck's constant, but I'm sure I'll google it later.
That and a bit more flesh on how Einstein's theory describes the mechanics of fission.
So, there. Lots of science. This book was definitely not written by Roach.
