Reading progress update: I've read 136 out of 414 pages.

Ok, more astronomy...but at least we got:
- a better explanation of Einstein's theories vaguely referred to in the first part of the book
- an overview of how different theories played off or refuted each other
- stories about cats
- elemental observations
- and an offer of a variety of theories on offer rather than, as the tone of the first chapters suggested, a linear narrative of why something is not right.
What I am still missing is a link between the science presented in the current and following chapters and the random discussion of quantum physics at the start of the book.
I'm going to stop here for today, as I need something lighter or just something with a bit more narrativium.
