...many years simply because faculty members and the graduate office have failed to give hard-headed advice at the right time, have shied away from making their students work hard enough, and have generally thought a well-bred air of amateurishness more gentlemanly and becoming than down-to-earth efficiency. If we put our heads to the matter, certainly we ought to be able to say to a good student: "With a leeway of not more than one year, it will take you so and so long to take the Ph.D...
...Either it or its successors can report on cosmic rays and solar radiation above the atmosphere. They can observe the density of the fringe of the atmosphere, its temperature and composition. They can judge the danger of meteors, the reefs and shoals of space navigation. They can observe the earth's gravitation, its magnetic field, its electric charge, and the cloud patterns of its weather in ways that are impossible for earth-bound humans. Some of these jobs might be difficult for a light satellite, such as the 21.5-lb. U.S. Vanguard. But a properly equipped satellite could take...
...them, but this is not at all like keeping humans alive on a satellite or other space vehicle. The difficulties are enormous, and much greater weights of life-preserving equipment must be lifted into space than is possible with today's biggest rockets. The problem of return to earth looks tough too. At the present state of the art, men who fly into space could not return alive...
Many imaginative military planners have dreamed of satellite fortresses armed with nuclear missiles to shoot at the earth below. All space vehicles must be lightly built to conserve weight. They would therefore be vulnerable, and since they are forced to move on predictable orbits, they should not be too hard to shoot down. One suggested method of dealing with a hostile satellite is to shoot a modest rocket into its orbit, but moving in the opposite direction. The warhead would burst and fill the orbit with millions of small particles. Any one of these, hitting the satellite with twice...
Tomb & Church. Around 322, Christian Emperor Constantine affronted the wealthy tomb owners by ordering the construction of a great ramp of earth from the side of the hill against which the tombs nestled. Ruthlessly, though with great care not to disturb the dead, most of the tombs were sliced off to the level of the ramp, and their interiors were rammed full of earth. On this ramp Constantine began the construction of the first Church of St. Peter...
