Intellectural treats, whimsy, but deep. Illustrated with lovely drawings by Gamow himself. Much of it can be understood by a child, and other parts might require a little concentration. All of it is great fun. The author Gamow started in nuclear physics, during the Golden Age of Physics, worked with Niels Bohr, then later in the US, on the Manhattan Project during WWII, and after the war, he was professor in Boulder Colorado. The books he wrote are pearls, and they have been equally popular with my parent's generation as with mine. Luckely some have been reprinted! Other Gamow titles: Biography of Physics, Atomic Energy [dedicated to the hope of lasting peace], Physics of the Strapless Evning Gown,...We are lucky that Dover has reprinted some of them. Do more Dover!
