What seems certain now is that, for the moment at least, Israel is the absolute master of the Middle East; it need take orders from no one, and can dictate its own terms in the vacuum of big-power inaction, U.N. fecklessness, and Arab impotence...
...secret is liquid air-a mixture of oxygen and nitrogen supercooled to - 318°F. It is pumped into vacuum-insulated Dewar tanks, sophisticated thermos bottles that protect the icy liquid from the warmth of the surrounding water and at the same time keep the diver's back and shoulders from freezing. From the tanks, the liquid air is piped through warming coils that heat it until it expands into breathable gas. Only hazard: since liquid air allows the diver to stay under far longer, he must surface slowly, in stages, to avoid the bends...
Chances are that it will seem increasingly strange to the Harvard community too as months pass. The HPC seems now to exist in a vacuum. It is sheltered above by the good will of Monro and below by the apathy of the masses, from ever having actually to define its role. Established by student referendum to "cooperate with Faculty and administration," the HPC has played it just that way. It sees its role, in Trosper's words, as "providing a structured way to present student opinion in some semblance of a well thought-out consensus. Then we have to trust...
...Curtain. Hovercraft were born in the fertile mind of British Aeronautical Engineer Christopher Cockerell in 1954. Testing his notion in true pioneer-inventor fashion, he attached a hose to the exhaust of an ordinary vacuum cleaner, stuck it through a hole in the top of an open-bottomed tin can, and watched fascinated as the can floated off the floor; the increased air pressure inside the can had pushed against the floor through the open end, lifting the can. Recognizing that the unhindered escape of air from the bottom of the can-and from the bottom of early experimental craft...
Ford's latest campaign involved all Cougars sold since the line was introduced last fall. The cars have a vacuum-powered headlight system, which slides a panel over the lenses by day, exposes them when they are switched on at night. Trouble is, in a few cases turned-on lights have been covered up unexpectedly, causing sudden blackouts. So Ford decided to play it safe and check every car, even though its engineers are sure that "the likelihood of this occurrence is not great." It is even less likely that the frank and open recall campaign will hurt...
