British physicist Padilla offers a lively and enjoyable volume on 3 tightly related subjects. The several mostly-math delvings focus on unimaginably large integers (such as Graham's number and Tree(3)), extremely small real numbers, symmetry, and the Cantorian infinities. The mostly-physics ones include relativity, entropy, quantum theory, and theory of particles such as the Higgs boson. And some of the mostly-cosmology ones address black holes, the anthropic and holographic principles, and dark energy. His non-dismissal of multiverse theories and optimism for string theory will not endear him to physics blogger Peter Woit.

An interesting read exploring physics, mathematics, and the history of their development. At times it was a little meandering and difficult to follow and the metaphors were hit or miss. Still, you could tell it was written with a real passion and the subject was something I was glad to learn more about. ( )
