#BookReview: The Janus Point by Julian Barbour

Intriguing Theoretical Astrophysics. If it wasn’t clear from the description of this book, this book is *all about* theoretical astrophysics and the author’s new theory of the origins and nature of time. If words like Newtonian and General Relativity and Leibniz and thermodynamics are part of your every day lexicon, you’ll probably enjoy reading this. For the rest of us… at least there isn’t much math involved in the actual text here? Specifically of the Calculus variety, which gives even many math-oriented people the heebie jeebies? Truly an intriguing work, but I’ll be the first to say that I didn’t fully follow or comprehend all of it – it is simply that high level. Even though Barbour tries to use narrative examples and structures designed to allow most anyone to have some idea of what is going on, at the end of the day this is still advanced theoretical astrophysics, of the kind that even Stephen Hawking wrestled with. While others more learned in the actual science may find fault here, for what it is I could find none. Very much recommended.
