In the close-up from the Cassini spacecraft, some of Saturn’s rings look rather like grooves in a phonograph record. I wonder if anyone has tried mapping those grooves to see if they can be played using the method described in “Groovy Pictures: Extracting sound from images of old audio recordings” (SN: 5/29/04, p. 339: Groovy […]

The counterintuitive finding that atrazine is more likely to kill tadpoles when it is highly diluted reminds me of a similar phenomenon in the alternative health care practice of homeopathy. Tracy SellersRowlett, Texas

The teardrop shape of Venus away from the centermost part of the sun simply is caused by the photographic surface being planar, rather than spherical. The image can never be represented without distortion for the same reason that the globe can’t be represented without distortion on a flat map. Robert P. Kelso San Marcos, Texas […]

Language of music The study by Hyde and Peretz about people inept at all things musical (“Brain roots of music depreciation,” SN: 5/8/04, p. 302: Brain roots of music depreciation) made me think of my spouse of 20 years. In addition to a lifetime of utter tone deafness, he also nearly didn’t receive his graduate […]

I don’t think anyone should be surprised that squirrels have figured out how to say “nyah, nyah” to rattlesnakes. After all, it’s what they’ve been saying to cats, dogs, and bird-feeder owning humans for years. R. Kelly WagnerAustin, Texas

Whale, of an annoyance In “Din among the Orcas: Are whale watchers making too much noise?” (SN: 5/1/04, p. 275: Din among the Orcas: Are whale watchers making too much noise?), Rus Hoelzel states, “One thing I want to make clear is that I think whale watching is a good thing.” He then states that […]

It is very disappointing that this article has not a word about any disagreement surrounding the health and related consequences of global warming, let alone of any disputes about its very likelihood. Tibor R. MachanOrange, Calif. The article asserts that malaria and other tropical diseases will migrate northward with global warming. This ignores the fact […]

I was surprised to find no mention of Linus Pauling’s theory of anesthesia in this article. In 1961, Pauling provided detailed arguments that interactions between anesthetic agents and water, rather than lipids, form hydrate microcrystals in the brain that entrap side chains of proteins and interfere with electrical oscillations. Stephen Lawson Linus Pauling Institute Corvallis, […]
