Elegant Solutions: Ten Beautiful Experiments in Chemistry

Tue, 11/01/2005 - 00:00 -- Hal Harris

Choose ten exemplary chemistry experiments. The synthesis of nylon? Bakelite, the first man-made polymer? The structure of DNA? The fixing of nitrogen? The discovery of buckyballs? Sorry, but none of those made the list of veteran science writer Philip Ball. Mr. Ball was looking for something other than mere importance.

The Art of the Catapult: Build Greek Ballistae, Roman Onagers, English Trebuchets, and More Ancient Artillery

Mon, 08/01/2005 - 01:00 -- Hal Harris

Gurstelle also wrote "Building Bots: Designing and Building Warrior Robots", but I haven't read that one. "Catapult" is definitely in the spirit of "build it yourself", that I like to encourage here and also in "The Cost-Effective Teacher" feature in the print Journal.

The Fly in the Ointment: 70 Fascinating Commentaries on the Science of Everyday Life

Joe Schwarcz has done it again. This host of a science call-in show in Montreal and Toronto has put together another collection of his commentaries on the science of everyday life. All four of his previous books have been "Hal's Picks", and you can find all of them in the Index. As usual, most of the science is chemistry.

It was not that many years ago that one could reasonably defer judgement about global warming. But the evidence that our planet's climate is changing at a pace that can only presage disaster is becoming so compelling that only the US executive branch can't see it. Even the Bush administration now acknowledges that there may be a problem, but not one that would require significant action.

A Mathematician at the Ballpark: Odds and Probabilities for Baseball Fans

Sun, 05/01/2005 - 01:00 -- Hal Harris

Back in the 1960's, I was captivated by "Percentage Baseball" by Earnshaw Cook. Now long out of print and a collector's item, this book was a forerunner of the "science" of SABRmetrics (after the Society for American Baseball Research) that refers to the scientific (statistical) evaluation of the game.
