Final book of the year. I highlighted a lot. I don't pretend to understand everything that was presented but the thing I want to remember from his book is that the universe is composed of events, not things. And the entropy of our universe is always greater than or equal to zero, it never decreases. The origins of the universe were nearly zero entropy and we've been shuffling the deck into more disorder (wrt the original layout of cards) ever since. Time isn't factored into any equations except where heat is involved. Time is relational between our perspective and what we observe, it's not independent or a "prioritized" variable, according to him.
