Your article describes a great theory in a theoretical world. The purpose of a coin toss is to determine an outcome in the real world, however. Did the guys doing the various analyses factor in the effect of the coin bouncing on the ground or being fumbled in an attempted catch? Ed EiermanRomney, W.Va. The […]

It’s tough in there In the arts, we say that material, such as paper, that deteriorates readily because of its composition (“News That’s Fit to Print—and Preserve,” SN: 1/10/04, p. 24: News That’s Fit to Print—and Preserve) has “internal vice.” I suppose that could be said of newspapers on several grounds. Lawrence Wallin Santa Barbara, […]

The genetic link from obesity to macrophage production to inflammation to diseases in this article seems convincing. On an ecological scale, inflammation is an acute response to environmental insult, while fat is a chronic response, through its role in sequestering toxins. Perhaps the new research reveals a genetic program to arm the body’s defenses both […]

In answer to this article, infections elevate activity of the immune system, so they might indirectly suppress tumors of all kinds. If so, antibiotics could increase the incidence of cancer by reducing the duration and degree of infection. The widespread practice of sterilizing our home and work environments could have a similar effect. Edward P. […]

Your article says that tsunamis “disrupt winds,” leading to the appearance of dark bands. I propose that upwelling above the crests creates a new surface initially unaffected by the wind and therefore slick. Such bands of slick water formed by tides are a common sight in Puget Sound.

Thin skin I find the language of “Thin Skin” (SN: 1/3/04, p.11: Thin Skin) to be judgmental and unscientific. For example, “desert pavement and their biota are wounded by human activity” is neither artistic nor scientific. Such narrow, biased views of ecology have no place in a scientific journal.

Paint by Pixel
Aaron Hertzmann is both a computer scientist and a painter. Among his art-related programming projects, he has developed a way for computers to refashion images and animations to reflect different painting styles. Other work includes a stretched “canvas” that projects a continually-changing painting of the viewer and a learning-by-example system that animates characters based on […]

In this article, I read that an orb of a given size, when slightly flattened, will pack more densely than when perfectly round. No kidding? Do you suppose if we were to crush cars into little cubes we could hurl more into a landfill than we could just by driving them over a cliff? What […]

Revealing words “Bookish Math: Statistical tests are unraveling knotty literary mysteries” (SN: 12/20&27/03, p. 392: Bookish Math) skipped one of the most significant methods for analyzing text for authorship. On March 11, 1887, Thomas Corwin Mendenhall reported in Science a straightforward method of plotting word length versus frequency. The beauty of this method is that […]
