I thought this article was quite interesting, but I would derive a different conclusion than did the scientists featured. I would not presume that Easterners have less capacity to make logical inferences than Westerners, but that they give logical inferences less import. The primary religions in the East–Confucianism, Taoism, and Buddhism–stress the importance of harmony […]

This article seems to ignore the fatal flaw in the search for the virtual person: While such a model is designed to represent all people, it in reality represents no individual. The ergonometric model says that a man is 5 feet, 9 inches tall and weighs 160 pounds. I can tell you–as a man 6 […]

Lasers act on cue in electron billiards
Electrons torn from atoms by a laser beam can shoot back into the atom and knock loose other electrons like balls in a billiard game, a finding that may have applications in nuclear fusion, particle acceleration, and fundamental physics experiments.

This article fails to point out interesting aspects of the land and ocean temperature data shown in the article. During the period from about 1918 until 1943, land and ocean temperatures rose at a rate of about 18C per millennium. From 1943 until about 1975, the temperature was constant or declined slightly. A period of […]
