...principle behind all antinoise devices is the same. Noise is basically a pressure wave traveling through the air. Antinoise is the mirror image of that wave, an equal and opposite vibration exactly 180 degrees out of phase with the noise to be blocked. When noise and antinoise collide, they interact with what is called destructive interference, canceling each other out. The idea is not new; generations of high-school physics students have seen destructive interference demonstrated with undulating Slinkies or jump ropes. But it is only recently -- with the advent of small, high-speed signal processors -- that scientists have...
Though that progress was slight, the bombers were evidently determined to destroy it. Many Lebanese speculated that General Michel Aoun, the bitterest foe of the Arab League peace plan and the commander of fanatically loyal Christian forces in East Beirut, was behind the killing. Aoun has been outraged that the plan permits 40,000 Syrian troops to remain indefinitely in Lebanon. He had pronounced Moawad's election void and vowed to throw out the Syrians. Aoun is too weak to achieve that goal but was strong enough to cause havoc. Before the assassination, thousands of his mostly youthful supporters crowded...
...fresh-faced as the blue-collar father, brings hot-tempered passion to the role. And Lahti, possibly the best actress in America working in TV (she won an Emmy nomination for her performance in the mini-series Amerika), is truly heartbreaking.

...repairing the physical destruction is only the beginning; next comes the damage control. Dec. 15 marks the start of the high tourist season, and if tourists do not come back, neither will the islands. More than 10 million visitors came last year, leaving behind $7.3 billion. After Hugo, cancellations poured in, even for destinations not touched by the storm. "Part of our problem is fighting people's terrible knowledge of geography," says John Bell, executive vice president of the Caribbean Hotel Association. "There were groups dropping out of trips to Aruba and Barbados, which were hundreds of miles from Hugo...
...group of rebels was apparently trapped by the army as it moved along a ravine behind the Sheraton, and fled into the shelter of the lobby. The guerrillas probably did not know that among the guests were the Green Berets and Joao Baena Soares, Secretary General of the Organization of American States, who was trying to work out a cease-fire. As the rebels took up residence in the Sheraton's VIP Tower, Salvadoran commandos hurriedly escorted Soares out of the hotel and drove him away in an armored car. The Green Berets were not so fortunate. Armed with...
