Exploring the Art and Science of Stopping Time: The Life and Work of Harold E. Edgerton

Thu, 06/01/2000 - 01:00 -- Hal Harris

This is the first time that something not printed on paper has been chosen for Hal's Picks, and it probably will not happen often in the future. This particular subject is, however, better treated in digital format than in a book (although several good books on Edgerton and his work are also available).

Ingenious Pursuits: Building the Scientific Revolution

Mon, 05/01/2000 - 01:00 -- Hal Harris

A year or so ago, I greatly enjoyed reading another book by Lisa Jardine, "Worldly Goods: A New History of the Renaissance", but I couldn't justify it for "Hal's Picks" because it didn't have much scientific content. When I heard about "Ingenious Pursuits", I bought it from a book club and read it right away.

Sport: Extreme Stargazing

Wed, 03/01/2000 - 00:00 -- Hal Harris

For anyone who has tried unsuccessfully (like me) to find familiar stars in well-known constellations through a telescope, the competition that David Freedman describes sounds impossible. The "sport" is to see how many of the 110 celestial objects in the Messier catalog you can locate and identify during a single night of observation.

Medicine on Mars

Thu, 02/03/2000 - 02:00 -- Hal Harris

I'm not a big fan of science fiction. I find "real" science to be generally more interesting; the fictionalized kind usually requires me to pretend that the universe is far different than what I believe to be the case. In fiction, travel between planets (or even solar systems) is accomplished quite easily, by suspension of the speed limit imposed by relativity.

World Records in Chemistry

Wed, 02/02/2000 - 01:00 -- Hal Harris

These authors address a few of the same questions as do Karukstis and Van Hecke, but they take aim at a somewhat more technically sophisticated audience; instead of trying to enhance chemical education near the introductory level, they are speaking to practicing chemists, some of whom may also be teachers.

Chemistry Connections: The Chemical Basis of Everyday Phenomena

Tue, 02/01/2000 - 00:00 -- Hal Harris

Kerry Karukstis and Gerry Van Hecke teach undergraduate chemistry at Harvey Mudd College (my alma mater), and Gerry was a student there at the same time I was (sometime in the previous millennium). They have collaborated on a very useful and engaging supplementary book for introductory and organic chemistry.

The Looking Glass

Sun, 01/02/2000 - 01:00 -- Hal Harris

Artist David Hockney has a theory that some of the "old master" portrait painters secretly used cameras(!) to help them sketch their subjects. No, he's not saying that they had Polaroids or film. However, the camera obscura was available in the early 18th century, and the more practical camera lucida was invented in 1807. Did the great artists use these devices?
