An ideal companion to "The Universe in a Nutshell" is this article by Neil Ashby, a Professor of Physics at University of Colorado - Boulder. Hand- held GPS devices have become standard equipment for boaters, hikers, and technology junkies. It is now taken for granted that one's position on the earth can be obtained within a few seconds, accurately, and free.

I was amazed at the popularity of Hawking's "A Brief History of Time" in 1998. Not because it was not a great book, but because the average reader's background in relativity, quantum mechanics, and cosmology is limited to their discussion in Star Trek.

Those of us who were fans of the old "Amateur Scientist" column of Scientific American will enjoy this collection of projects that look to be fun to build and to play with. These are all things that the author has invented or adapted for a Saturday Science Club for kids near his home in Guildford, UK.

One of the goals of a course I teach in our Honors College is to provide non-science majors with the tools they need to differentiate authentic science from material that has merely been provided a "scientific" dressing. Physicist Robert Ehrlich has provided nine case studies that are ideal for this purpose. Do more guns in the hands of citizens decrease crime?

The word "Surviving" should probably be underlined in the title of this first-hand account by an American astro/cosmonaut of his experiences aboard Mir. There is precious little science in this book, but a great deal about living at the mercy of technology and Russian bureaucracy.
