Chemical Misconceptions - Prevention, Diagnosis, and Cure (2 Volumes)

I usually avoid writing in this space about materials that one might use directly in the classroom, since I am trying encourage teachers to expand their scope. However, this two -volume set recently published by the Royal Society of Chemistry is enough to make me change the rules.

The Odds of That

When nearly a dozen scientists, all in some way associated with research on biotechnology, die within a year of the 9/11 attacks, can it be coincidence? Yes, says Lisa Belkin, author of this excellent article on one of the constants of pseudoscience, the attribution of "cause" to random events.

One Good Turn: A Natural History of the Screwdriver and the Screw

It goes without saying (amongst males, at least), that one can never have too many tools. Most of us probably have more screwdrivers than any other tool, both because of their utility and their high vapor pressure (like my reading glasses), and so one needs to buy more in order to make sure that one will be available when needed.

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.
