I've spent a lot of time with Newton recently, helping (in a very minor way) with a new translation of the Principia. I know and like him; and so does Stephenson. This book isn't going to be for those who dislike digression. For those of us who can't get enough, it's Heaven sent.
As for The Gallic Wars? The moment I read "Gallia est omnis divisa in partes tres" I got the biggest grin on my face.
