”IN HIS INIMITABLE STYLE, ASIMOV MAKES SCIENCE EASY AND FUN WITHOUT TRIVIALIZING IT.”—A.L.A. Booklist

”LUCIDLY AND ENTERTAININGLY, ASIMOV EXPOUNDS ON PHYSICS, ASTRONOMY, CHEMISTRY, BIOLOGY AND TECHNOLOGY.…READERS WILL BE CHARMED.”—Publishers Weekly

Although I enjoy this particular collection of F&SF essays, I would not rate it as among the best. There is not an essay here which I don’t enjoy, but there are also few that stand out particularly. “What Truck?” is, perhaps, the best in the set. “More Thinking about Thinking” and “Updating the Satellites” are sequels to earlier essays. The others are a good and worth reading—just not outstanding.
