...large part of the controversy over the British-French Concorde arises from concern about the big jets' effect on the ozone layer, which protects life on earth from lethal doses of ultraviolet light. Laboratory tests and chemical theory have shown that the nitrogen oxides given off by jet engines destroy ozone. Do nitrogen oxides have the same effect in the stratosphere? A Dutch meteorologist working at Boulder, Colo., reports there is now evidence that the answer...
These results show the need for further research into the effects of technology on the ozone layer. Large solar flares occur infrequently, allowing the ozone layer time to be replenished by natural processes. But man's assaults on the ozone shield, in the form of SST flights, aerosol sprays and other chemicals, are continuous and could permanently deplete the layer...
Monk begins her solo huddled on a stool--an old, old woman in white leggings and frock. Traveling down a long white cloth, she journeys backwards in time. Her gestures compact layer upon layer of implied meaning. Wide-armed swaying conjures up the image of a little girl dancing to the hypnotic rhythms of her favorite ditty, but suggests too an ancient woman casting nets, sowing grain, soothing a child...
When Derek Bok became president of Harvard in 1971, he quickly tried to establish a decentralized bureaucratic system of leadership. The University was already deeply fragmented into autonomous faculties and departments. But Bok created another layer; he erected a wall of people to take care of Harvard's time-consuming administrative and functional details. While there were only a few special assistants to protect former president Nathan M. Pusey '28 from the bureaucratic flood, Bok created four vice-presidents, a general counsel, and an expanded team of special assistants to handle his administrative chores. At the time of his inaugural...
America (as we all know) believes in "free" trade, but not so free that U.S. industry is outdone. So feeble excuses like destruction of the ozone layer are put forth, even when every chemist knows that the Concorde would have an infinitesimal effect on the ozone layer, which is already being so effectively destroyed by the hydrofluorides in spray cans...
