Paperback review: Gravity’s Engines, by Caleb Scharf

I don’t know much about science but I do know what I like, and I like books like this which fill me with a sense of wonder – both at the universe and the human ingenuity which makes sense of it. In lucid, often poetic language, Scharf describes the awesome powers of black holes, those giant collapsed stars whose gravity is so powerful that not even light can escape them, and which gobble up stars as snacks.

Review: What A Wonderful World, By Marcus Chown

Reading a well-written popular science book is one of the great pleasures of modern times, and this guided tour through life, the universe, and everything affords that pleasure in abundance. Marcus Chown takes us by the hand and leads us through the labyrinthine mysteries of the origins of life, evolution, the cells of the body, the brain-boggling brain, electricity (I’ve never understood what that stuff is; I still don’t, but my ignorance is now better-defined), the crazy truths of quantum theory, gravity, time, stars, and black holes. You can get drunk on the sheer strangeness of the theories – for instance, you have an infinite number of doppelgangers, and the nearest one is 10^10^28 metres away. And we may all be holograms.
