One Two Three . . . Infinity: Facts and Speculations of Science

  One Two Three... Infinity, subtitled Facts and Speculations of Science, was originally written by George Gamow in 1947 and then revised somewhat in 1961 (unfortunately, George Gamow died in 1968 and it was the last revision). It's an amazing tour of some of the more interesting bits of physics, with a bit of mathematics and biology thrown in, covering in some depth many separate topics in under 350 pages.
