The author then takes the first of a number of ruminative breathers, speculating on the button. The Romans used buttons only as ornaments and even the ancient Chinese never progressed beyond the toggle and loop. Unlike the handsaw, which was refined over time, the button and its buttonhole simply appeared in northern Europe in the thirteenth century--true works of an anonymous inventive genius. Then we proceed to an influential treatise on ingenious machines published in 1588 by Agostino Ramelli, a military engineer. Among the machines is a bookstand that revolves like a Ferris wheel, holding eight books at a constant angle by means of a gearing system used in astronomical clocks. The author comments: "Of course, gravity would have done the job equally well (as it does in a Ferris wheel), but the gearing system allowed Ramelli to demonstrate his considerable skill as a mathematician." Then the author writes: "This splendid folly distracts me-I''m supposed to be looking for screwdrivers." "It was just a strange thing that happened," Ocean View Police Chief Kenneth McLaughlin told the News-Journal, "a very, very unfortunate accident." The young carpenter died at the Peninsula Regional Medical Center in Salisbury, Md., after being evacuated by helicopter.A nail-gun accident in Mississippi had a happier outcome, reports the Biloxi Sun-Herald. Stone County, Miss., contractor Duncan Hatten was crouching down to nail a 2x4 block onto a column when he lost his balance and fell against the nail gun, which cheaptransferswitchesforstandbygenerators fired two quick nails into his heart. "I just figured I was gonna die," Hatten told local TV station WLOX. "I told my coworker to tell my family that I loved them." But the two framing spikes had narrowly missed major blood vessels, cheaptransferswitchesforstandbygenerators and surgeons cheaptransferswitchesforstandbygenerators were able to remove the nails from Hatten''s heart in a two-hour operation. ©2003 www.standbygenerator.net.
