    Exploring Time

    This new educational site offers time-lapse and high-speed video clips, 3D scientific animations, and other visually stunning features that reveal how events unfold on different timescales—from billionths of seconds to billions of years—and take place too quickly or too slowly for the human senses to perceive.

    A concern I have for a new route algorithm to replace algorithms that “may overlook shorter routes for the sake of following major highways” is exemplified by the fact that here in southern Oregon, every winter, people get lost and occasionally die taking the “shorter routes” as suggested by car-navigation systems or online trip plotters.

    Mere kats? “Science behind the Soap Opera” (SN: 3/3/07, p. 138) shows that meerkats bear an uncanny resemblance to human beings. We, too, have an innate sense of responsibility for our group and individually commit acts of unspeakable violence. John HagerhorstFrederick, Md. Just a dram “Natural-Born Addicts: Brain differences may herald drug addiction” (SN: 3/3/07, […]

    I was surprised that the findings on the brain’s processing of information and discerning of relationships would come as a surprise. I have long been aware of, and have even come to count on, the fact that a surprising degree of insight and clarity often comes in the morning after having fallen asleep the night […]

    No mention was made in this article of the possibility that, being so close to its star and having a 13-day orbital period, the planet would keep the same surface to the star. Having one side baked by unrelenting sunlight and the other side frozen would leave only a narrow ring between eternal day and […]

    The NASA researchers baffled in this article by the hexagonal shape in Saturn’s soupy atmosphere at its northern pole should read “As waters part, polygons appear” (SN: 6/3/06, p. 348). It is worth investigating whether there is a similar phenomenon—I still suspect some sort of standing sine wave effect—at work in both cases. Ellery FrahmMinneapolis, […]

    The lines on the cave ceilings remind me very much of what a large pot of finger paint looks like after children extract what they want to draw with. I could easily see my children (especially when younger) drawing on their own faces and bodies all kinds of designs using the colored clay. Dan WoitulewiczDetroit, […]

    Long ago gas Finding CO2 levels that are 2,500 times higher in 5,000-year-old fulgurites than in modern samples, scientists have speculated that the extra CO2 resulted from vaporization of organic material by lightning (“Stroke of Good Fortune: A wealth of data from petrified lightning,” SN: 2/17/07, p. 101). Could some of this gas reflect elevated […]
