...been wholly in sympathy with McNamara's gradualist increase in military pressure on North Viet Nam. Wheeler agrees with the theory of flexible or graduated response to aggression, but believes that the restraints the U.S. has imposed on its war effort have unnecessarily blunted its potential impact. "You either fight a guerrilla war or a limited war or a tactical nuclear war or a full-scale nuclear war," says a member of the Joint Staff who reflects Wheeler's overall views...
...itself as "designed for the modern man," 17 courses are partly taught by computer. In Geography I, for example, the machine leads students through such questions as: "How does geography's focus differ from that of the other social sciences?" (Correct answer: "Geography is interested in the spatial impact of all categories of human behavior, whereas other disciplines tend to focus upon a single category.") If the student respends with any or all of the key phrases in the answer, the computer replies "good," or "excellent," and proceeds to the next question...
What they point out about the effects of third parties is for the most part unquestionable. But all previous efforts have been launched in the hope of electoral success, however that was defined. To run an independent candidate with any impact at all requires a degree of enthusiasm which the Levinson-Kearns argument fails to inspire.

...which are found in several areas around the world, were formed when meteorites or comets collided with the earth. The en- counters were so catastrophic that bits of the earth, as well as chunks of the intruder, were hurled into space and then fell back. Heated both by the impact and their swift passage through the atmosphere, they were fused into glassy globules...
...Heezen and Glass, the coincidence implied that one phenomenon may have caused the other. The impact on the earth of a mile-wide meteorite might well have disturbed the complex motions of the earth's core that are believed to generate the magnetic field. As a result, the geologists suggest, the field may have flipped. It is also conceivable, they say, that at least some of the previous reversals of the magnetic field were caused by the catastrophic collision of huge meteorites or comets with the earth...
