  1. Remember Typewriters?

    Richard Polt, a philosophy professor at Xavier University, celebrates a (nearly) obsolete technology at his “Classic Typewriter Page.” His site features a brief history of typewriters, facts about the “little charmers” known as Remington portables, and many other tidbits of information concerning this handy writing device.

    ARTIFICIAL LIGHTNING FLASHED AT 10 MILLION VOLTS The most powerful manmade lightning is flashing across the cover of this week’s Science News Letter from new equipment in the Pittsfield laboratories of the General Electric Co., which has twice the capacity of any preceding apparatus of its kind. This is a discharge through a 15-foot space […]

    That six college students in London should require more brain activity than Italian students in decoding words is consistent with the use of whole-language methods favored in London classrooms when these respondents were young. For people not trained in phonics, word decoding is more difficult. A more complete study would include students from Scotland, where […]

    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 […]

    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 […]

    It’s always risky to assert that a particular study has never been conducted. The research may have been done and, worse, the researcher may come across the assertion. This article claims, “Long-term studies of tough boys have yet to be conducted.” In 1987, we reported a 9-year follow-up of 25 boys (Contributions to Human Development […]

    HUGE SHOVEL CAN LIFT CAR OF COAL The largest shovel in the world, with a scoop big enough to pick up an automobile, is the subject of our cover illustration. It is in use at the Fidelity mine of the United Electric Coal Co., near DuQuon, Ill., the greatest coal-stripping enterprise in the world. Electrically […]

    Regarding this article, as planes fly low over the bay to land at San Francisco airport, wing vortices frequently bend down and become twin waterspouts that last up to 20 seconds. Dave GrossmanPalo Alto, Calif.

    MUDDY MISSISSIPPI YIELDS PEARLS THAT RIVAL ORIENT’S Pearls we usually picture as coming up from limpid greenish tropical sea depths, in the fingers (or perhaps the mouth) of a swimming brown-skinned native. It seems a bit of a comedown to think of pearls coming out of the prosaic waters of the muddy Mississippi–and as a […]
