Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters

Fri, 02/01/2002 - 00:00 -- Hal Harris

I first wrote about the controversial thesis of this book back in January of 2000, when my "Pick" was an article about David Hockney by Lawrence Wechler in the New Yorker. With the publication of this very attractive, large-format book, you can look for yourself at the evidence that he argues shows that many of the great master painters secretly used optical devices to help produce their work.

Ice Memory

Ice cores, bored through thousands of feet of stable glacial ice in Greenland, have proved to be our best record of global climate over more than a hundred thousand years.

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

Sat, 12/01/2001 - 00:00 -- Hal Harris

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?

Naturally Dangerous: Surprising Facts about Food, Health, and the Environment

Mon, 10/01/2001 - 01:00 -- Hal Harris

Professor James Collman of Stanford University has provided an excellent resource for all of us who try to help our students and the general public to discriminate between valid science and the bogus "scientific" claims that pervade television, the Internet, the grocery store, and especially the "health food" store.

Drugstore Athlete

Sat, 09/01/2001 - 01:00 -- Hal Harris

For a long time, it could be said that with some validity that drugs not help athletes perform better. That is no longer the case. It is could increasingly difficult to assure that amateur athletes, even high school athletes, are not training and competing with the aid of testosterone and its precursors, or erythropoetin.

Transforming Matter: A History of Chemistry from Alchemy to the Buckyball

Wed, 08/01/2001 - 01:00 -- Hal Harris

I've been reading a lot lately about alchemy, and was therefore delighted to find a new book on the history of chemistry (that includes some on alchemy), just published by Johns Hopkins University Press. Trevor Levere takes on the impossible task of chronicling the developments in chemistry from its beginning to the present, in only a little over 200 pages.

Nitric Oxide and the Control of Firefly Flashing

Mon, 07/02/2001 - 02:00 -- Hal Harris

As a physical chemist, I was amazed when it was discovered that the diatomic free radical, nitric oxide (NO) was intimately involved in the transmission of neurological information in mammals. Now a group led by Barry Trimmer at Tufts University has demonstrated that it is the key that turns on bioluminescence in fireflies.
