Physics, Metaphysics, and Poetry. I read the Audible version of this while driving to my hometown in another State (a solid book for such a mid-distance, 6 ish hr drive) and thus had the unique pleasure of having Alan Turing himself (as played in The Imitation Game and read here by Benedict Cumberbatch) lecture me on theoretical physics, metaphysics, philosophy, and poetry. If you're looking for a more concrete look at the exact theoretical physics at hand... this isn't the book you're going to want to pick up. If you're looking for more of an easy-read, high-level, pop science level look at whether or not time exists... this is a very good book from that perspective. And indeed, ultimately the text is all about perspective. At the most distinct levels, time simply does not exist, according to Rovelli. And yet obviously we humans experience time. So how can these two prior statements be resolved? Read this book for Rovelli's solid examination into the question and attempt at resolving this seeming paradox. Very much recommended. Particularly the Audible. :)
