...about the general sequence of events that followed. The tower ordered KLM to taxi the full length of the runway, make a 180° turn and hold. It ordered Pan Am to follow about three minutes behind and turn off at the "third intersection." There were four such turns (see diagram) providing runway access from the terminal apron and taxi strip. Ten planes congesting the apron blocked the jumbos from using the full taxiway to reach their takeoff point. KLM confirmed its orders and proceeded. Pan Am followed at about 6 m.p.h. In good weather, 20 m.p.h. would be normal...
Typically, the physician pushes several hollow steel needles horizontally into the breast through the tumorous area and out the other side (see diagram). Thin plastic tubes are then threaded through the needles (which are subsequently removed) and anchored in place by small plastic buttons at either end. The iridium-in the form of tiny "seeds" embedded in a thin, stiff nylon ribbon -is inserted into the tubes. The outer layer of the seed is a steel sheathing; it blocks dangerous ionizing beta rays (electrons), but allows the escape of the high-energy gamma rays that destroy the tumor...
...gets the impression of a jumble of particles and physicists. In fact, things were somewhat more orderly than they might seem. Glashow explains the scheme in a diagram accompanying an article he wrote last July. He first divides elementary particles into "carriers of force" and "carriers of mass." Carriers of force are the mediating particles described above (although the pion is not a member of this class). Carriers of mass comprise everything else...
...view the hologram is easy. A beam from a helium-neon laser is passed through one lens, which spreads it to cover the entire plate, through the plate itself and then through another lens, which acts as an optical computer and converts the spots into a coherent picture (see diagram). The result is an image showing the arrangement of atoms in one plane of the crystal. This image can be combined with images from other sections to give a three-dimensional view of the crystal's entire atomic structure. Says Stroke: "In the past, all we have been able...
Other active systems use water or various antifreeze solutions as a heat-conducting medium (see diagram). In Hyde's house, water heated by the sun to around 200° F. is stored in a 2,500-gal. tank. Hot water then circulates through a heat coil over which air is blown by a fan and ducted to every room in the house. At Harry Evans' new home in East Hampton, N.Y., heat from solar panels in the roof is collected in a bin containing 1,000 sealed, plastic bottles of water, which can hold the heat...
