...They also put in time on the footplate--where the fireman and driver stand, stoking the boiler, firing up the engine and managing the controls. In follow-up courses, groups of four students strive to acquire enough skill to drive the locomotive. This involves learning to clean, oil and light up the engine, shunt tracks, couple and uncouple cars--and brake, no easy task. John Sinclair, 54, technical director of a Bedfordshire computer firm, was "quite frightened" during an intermediate course with Severn Valley Railway because even at 25 m.p.h., the locomotive rattles and shakes. So pleased...
...LIGHT ON SAVING ENERGY Forget the dim glare of a classroom's fluorescent strip. The Twister from Lights of America--which makes only energy-efficient products--is a bright, compact fluorescent bulb that fits standard sockets, uses a fraction of the wattage of its incandescent cousins and lasts as long as seven years...
...building as the leading edge in high-rise construction. "We felt we would be creating an example here. Others would have to follow." He notes, for instance, that his tenants breathe air that is 50% fresher than that in most offices. That, along with an abundance of natural light, could perk up employees, hiking their productivity 10% or more, according to some studies. Durst calls this "the biggest argument for green buildings. If you can make people more efficient, that's a huge saving...
...Jupiter. When an international team of astronomers working at the Canada-France-Hawaii Telescope (CFHT) on Mauna Kea in Hawaii turned their attention toward Eugenia one evening last fall, however, they spotted something curious. Off on the upper-left corner of the fuzzy-looking image was another smear of light they couldn't identify. "These blobs are often artifacts of the optics," says astronomer William Merline, head of the team, "but this blob hung around. Once we saw it was moving in a pattern consistent with an orbit, we knew it was a satellite...
...Light streaming in from space tends to get distorted by the planet's atmosphere, causing a star's familiar twinkle. The CFHT, however, is equipped with optical hardware that lets it calibrate itself on the light from a known star--whose degree of atmospheric distortion will generally be predictable--and then use that information to correct the distortion of other, unknown bodies. A little fiddling with the incoming image and even the blurriest picture snaps right into focus...
