...still another pair of orbiting spacecraft are scheduled to make soft landings on the surface of the planet. In a search for any obvious evidence of life, TV cameras aboard the landers will take pictures of the immediate surroundings. Delicate instruments will sniff and analyze the atmosphere at ground level. Mechanical devices will gulp up, digest and chemically analyze Martian soil for clues to life. In their findings, relayed back to Earth by radio, man may find the exciting evidence that life exists elsewhere in the universe...
From grade school to graduate school level, groups of militant students have been effectively demonstrating their ability to disrupt and even shut down U.S. institutions of learning. On campus and off, more moderate types have been asking with increasing frequency: What about the law? Do the militants have a right to prevent other students from enjoying their rights? Last week, in a decision that firmly upheld a peaceful protest in Des Moines by five public school demonstrators, the U.S. Supreme Court also suggested that the Constitution does not protect demonstrations when they are disorderly and disruptive...
...other. He argues, for instance, that environment operates as a threshhold variable in affecting development. Below a certain minimum threshhold of environmental benefits, the genetic potential of an individual does not develop, and cannot be considered an important variable in determining IQ. But Jensen never quantifies the threshhold level. He merely indicates, somewhat arbitrarily, that minority-group students are not below it. They very well might...
...fact, whatever, genetic differences exist may be nothing more than the artificial products of oppression by a dominant society. Jensen himself admits that assortative mating--marrying at one's own level of mental ability--tends to raise the general level of intelligence by inbreeding genes which produce success. If social circumstances prevented a group's members from choosing their own marriage partners, or prevented the valuing of intelligence, environmental factors could have artificially depressed the natural level of intelligence in the group's population. Relieving those oppressive circumstances would, of course, permit readaptation and a return to parity...
...airlines therefore want to keep the basic fare for businessmen at a profitable level. At the same time, of course, they want to encourage more people to fly. Lower fares can greatly increase the numbers of non-businessmen using the airlines--grandmothers, students, housewives and virtually every middle-class group in society has a very elastic demand for air travel. In Ec 1 terms, the airlines know that through fare discrimination--one fare for the elastic sector and one for the inelastic business sector--they can greatly increase both their profits and the number of people...
