...Using their new biochemical tools, the scientists embarked upon some remarkable experiments. As usual, they turned to their favorite guinea pig, a lab strain of E. coli, and soon they had learned to insert with exquisite precision new genetic material from other, widely differing organisms into the bacteria (see diagram...
...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...
...fear of causing such a crash or a collision ?known with studied casualness as creating an "aluminum shower"?puts the controllers under tremendous strain from the time they clear a jet for takeoff until they guide it to a landing (see diagram). FAA psychological tests have shown that controllers undergo more stress than combat pilots. At Chicago's O'Hare Airport, the world's busiest, they are allowed to work for only 90 minutes at a stretch during peak hours, landing a plane every two minutes while simultaneously keeping track of half a dozen more...
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...
