I've been a bit under the weather lately, but I think I'm starting to get better. I'm well enough to post here anyway. Which is good, because I noticed a couple of books that I thought people might be interested in. Remember a few years ago when everyone was suddenly talking about "string theory?" This was because of a book by Brian Greene called The Elegant Universe, which somehow managed to solve a longstanding dilemma in the world of physics, that "general relativity and quantum mechanics cannot both be right," in a book readable enough to become a best seller. Greene proved to be one of those remarkable writers, of which there are very few, who have the ability to make a very boring and difficult topic interesting for everyone. And now he has a new book out: The Fabric of the Cosmos : Space, Time, and the Texture of Reality, in which he continues to unwind scientific complexities with a combination of analogy and wit.My friend Edan pointed out another interesting, new book to me other day. Dancing with Cuba: A Memoir of the Revolution by the remarkably named, Alma Guillermoprieto. Edan and I both read an excerpt of this book in the New Yorker a while back. I enjoyed the way Guillermoprieto's fierce Latin personality was tempered by her lyrical love of dance. This book seems perfect for anyone enamored by ballet and/or Cuba.A NoteFrom the book I just finished: "From his windows at MacGregor Road, he watched the President Polk leave the harbour. He knew nothing of President Polk, but assumed that the shipping company would have checked the record, beforehand, for anything scandalous. Then he did miss Audrey, with whom he could have spoken of such things."
