    Bohr no boor As described in “When the atom went quantum,” (SN: 7/13/13, p. 20), Bohr’s willingness to travel both paths when different viewpoints seemed to clash, yet both seemed to fit the data, was crucial to the development of quantum mechanics. Yet that willingness cannot be equated with acceptance of all possible views. Having […]

    Not-so-smart perception Researchers studying associations between IQ and selected visual tasks (“Less is more for smart perception,” SN: 6/29/13, p. 18) report that tracking small moving foreground objects, a task at which high-IQ subjects excelled, is often more important than detecting large-object motion or attending to background activity. They suggest that for driving or walking […]

    Invertebrate enigmas I found the recent article “Evolutionary enigmas” (SN: 5/18/13, p. 20) fascinating because I know of another example of an invertebrate animal possessing a “strictly vertebrate” quality. As a high school human anatomy and physiology teacher, I sometimes have my students test the effects of the constituents in cigarette smoke on live Daphnia […]

    Wet Earth Erin Wayman’s article “Faint young sun” (SN: 5/4/13, p. 30), about how the early Earth stayed warm enough for liquid water, made me wonder about the effect of the temperature of the planet itself. A hotter core, thinner crust, more volcanism — wouldn’t those factors in addition to atmospheric influences affect surface temperature? […]
