I have not yet finished the book. I find it rather technical and it that respect interesting, also for the interested layman as I am.
But I miss thus far an comprehensive overview of th origin itself. Or a sort of continuous thread by which the reader keeps track of the subject. The author switches continuously in its writing from technical and circumstancial details to the subject at hand.
I consider it rather hard work to read it, maybe, there is a reward before the end.
