There is something strange about this. I bought his "most difficult book", — Schild's Ladder — but I felt I should continue this one before I read it. And it suddenly feels easy! I actually understand a lot of what is happening even if sometimes I am a bit lost, especially with the experiments part, which one is which? But for the rest, it is reading smoothly and I am enjoying it again! I guess I did need a break from hard Sci-Fi.
