MAGNIFYING EYE WOULD SEE STRANGE THINGSIf we could only convert our eyes into magnifying glasses at will, we would see a lot of astonishing things that escape us now because they are too small. The little walking gargoyle shown on the cover of Science News Letter, for example.It is a juvenile stage of a very common insect, which we ordinarily pass by as just another “bug.” But here he is, magnified only 16 times by Cornelia Clarke’s camera, and he assumes an appearance more bizarre than the imagination of a Persian artist, more impossible than the figures in a medieval bestiary.PICTURES OF SPI...Published: Monday, July 2nd, 2001

For fans of major-league baseball, one of the highlights of the current season is the rate at which Barry Bonds of the San Francisco Giants is hitting home runs.Through June 25, Bonds has hit 39 home runs in 77 games, already setting the record for the most home runs before the all-star break in mid-July. At this rate, he could slug 82 homers by the time the 162-game season ends. That number would easily surpass the record-setting 70 home runs that Mark McGwire of the St. Louis Cardinals hit in 1998.The popular statistics journal known as The Sporting News has gone even further in its trend an...Published: Friday, June 29th, 2001Found in: Numbers -

LARGER MERCURY VAPOR ELECTRIC GENERATING UNIT BEING BUILTA new and larger turbine electric generator that will use mercury vapor instead of steam and will consume less fuel than corresponding modern steam plants is being constructed in the General Electric Company plant at Schenectady, N.Y.This 20,000-kilowatt turbine will have twice the output of the mercury vapor engine and generator that General Electric engineers claim has already proved its superior efficiency over steam turbines during a year’s test at Hartford, Conn. The new plant will be even more efficient than the Hartford station, i...Published: Monday, June 25th, 2001

Lead, a toxic heavy metal, can show up in the most unexpected places. For instance, several recent studies documented a worrisome tainting of calcium supplements. Just last month, some Mexican lollipops were recalled from U.S. stores upon a finding that their wrappers had leached lead into the candy. And recently, this column recounted the perils of a man poisoned by his bathtub winemaking operations.Of course, people can be exposed to lead through more obvious means—by breathing fumes in metalworking plants, eating foods tainted by emissions from cars burning leaded gasoline, exposure to pee...Published: Wednesday, June 20th, 2001Found in: Nutrition -

For anyone deeply interested in logic and the history and philosophy of zero, Hossein Arsham of the University of Baltimore offers an thought-provoking Web-based discussion of such topics as the meaning of division by zero, the role of zero in limits and divergent series, and the concept of zero as a void.Go to: http://ubmail.ubalt.edu/~harsham/zero/ZERO.HTMPublished: Monday, June 18th, 2001

HUGE ELETROMAGNET INSTALLED AT LEIDENA huge electromagnet weighing 14 tons, about two-thirds as much as a street car, just erected at Leiden, Holland, by the Siemens Halske Company of Berlin, will enable scientists to wrench atoms apart as never before. This marks the realization of a dream of the late Dr. H. Kammerlingh Onnes, the first man to liquefy helium, who designed the magnet.The joint action of intense magnetic force with intense cold is likely to yield new secrets about atoms, is the belief of Prof. Onnes’ successor, Prof. W.J. Haas, who completed the work. Dr. Peter Kapitza, of the ...Published: Monday, June 18th, 2001

Predicting the geometric shapes of soap bubble clusters can lead to surprisingly difficult mathematical problems.Frank Morgan of Williams College in Williamstown, Mass., recently illustrated such difficulties when he invited an audience of mathematicians, students, and others to vote on which one of a given pair of different representations of the same number of clustered planar bubbles would have a smaller total perimeter. Assembled for a ceremony at the National Academy of Sciences in Washington, D.C., to honor the 12 winners of the 2001 U.S.A. Mathematical Olympiad (USAMO), audience members...Published: Friday, June 8th, 2001Found in: Numbers

TWIN ALBINO ROBINS HATCHED WITH NORMAL BIRDTwo albino robins, highly interesting and rather rare oddities in the bird world, have been watched from hatching to early maturity at the home of H.D. Shaw of Grinnell, Iowa, and had their pictures taken by Miss Cornelia Clarke, nature photographer.“The nest was built high up on the ledge of the porch where it wad sheltered and partly hidden by the vines,” Miss Clarke writes. “There were three eggs in the nest. Two hatched the albinos and the third an ordinary brown robin. The parents were normal in every respect except that the mother robin had two ...Published: Friday, June 8th, 2001

Artist Susan Happersett of Jersey City, N.J., has come up with a novel twist on the venerable Möbius strip: a playful, eye-catching creation she describes as a Möbius accordion.A Möbius strip, or band, is the remarkable one-sided surface that results from joining together the two ends of a long strip of paper after twisting one end 180 degrees. Mathematicians, magicians, artists, and many others have been playing with this intriguing object since its discovery in the 19th century by August Ferdinand Möbius (1790–1868), a professor at the University of Leipzig in Germany.Happersett combines her...Published: Wednesday, June 6th, 2001Found in: Numbers -
Over the years, many studies have linked skin rashes in some people to working long hours at personal computers. A Swedish study now finds a possible explanation: Certain computer monitors emit a chemical that can cause allergic reactions.Three years ago, while analyzing pollution in samples of outdoor air, Conny Östman and his colleagues at Stockholm University realized that something in their lab was tainting the glassware they used. It was triphenyl phosphate, a flame retardant added to many plastics. The chemists eventually traced this contact allergen—which they later also found in the ai...Published: Monday, June 4th, 2001Found in: Environment
