Einstein's Clocks, Poincare's Maps: Empires of Time

When I bought this book, I didn't realize how complementary to my Pick for Marchit would turn out to be. I thought that Poincare's "maps" referred to were his geometric depictions of deterministic chaotic systems, which he was first to discover, and the book was going to be largely about mathematics.

Relativity and the Global Positioning System

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.

The Universe in a Nutshell

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.

Vacuum Bazookas, Electric Rainbow Jelly, and 27 Other Saturday Science Projects

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.

Nine Crazy Ideas in Science: A Few of Them Might Even be True

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? Is AIDS really caused by HIV?
