Unsolved Mysteries of Science: A Mind-Expanding Journey through a Universe of Big Bangs, Particle Waves, and Other Perplexing Concepts sounds like a mouthful. It wasn’t as easy to read as other science books I’ve been reading, I think because it isn’t in interview or story form. This book asks questions and answers them very well. But some of the questions weren’t mine. I don’t care about big bangs; I understand about particle waves, at least as well as I’m going to; and though I read “What is Red?” I wasn’t that enthralled.
I did like the explanation of how many dimensions there are (10 or 26 for string theory, maybe 11 with a second time dimension). That was eminently readable.
I also read and enjoyed “Are There Multiple Universes?” and “Why Is There So Much Quantum Frustration?”
So I would recommend this book if you have little or no knowledge on the subject, or if you have a specific question that is answered by the author, John Malone. It was interesting as a primer, but I’ve read a lot on some of his question areas.
