Over 120 delightful pen-and-ink illustrations by the author add another dimension of good-natured charm to these wide-ranging explorations. A mind-expanding volume for the layman and the science-minded. By one of the leading physicists of the twentieth century, George Gamow's One, Two, Three...Infinity is one of the most memorable popular books on physics, mathematics, and science generally ever written, famous for having, directly or indirectly, launched the academic and/or scientific careers of many young people whose first real encounter with the wonders and mysteries of mathematics and science was through reading this book as a teenager. Untypically for popular science books, this one is enhanced by the author's own delightful sketches.
