...result of this feathering action will be to push the satellite into an elliptical orbit that grows longer and longer until the earth is so far away that its gravitation is negligible, and the satellite can break loose. Dr. Cotter estimates that a 50-lb. space sailer could escape from the earth in about six months...
Orbit to Orbit. Once free from the earth, the space sailer would fall into a solar orbit, use sunlight to waft it almost anywhere in the solar system. For such maneuvering it would need a way to change its sail's angle to the sunlight; Dr. Cotter believes that this can be done by gyroscopic devices that act in response to radio signals from the earth. With its sail broadside to the light, it will be pushed farther and farther from the sun in wider and wider orbits. Eventually it will reach the orbits of Mars or the outer...
...bring the space sailer back to the earth's orbit, the operator on earth could reset the sail at such an angle that sunlight bouncing off would tend to reduce its orbital speed. As the speed slowly diminished, the space sailer would spiral inward toward the sun, eventually returning to the earth's orbit...
Even abstract expressionists themselves have been rediscovering Velásquez. Perhaps the cold, snowy veil that abstraction has cast over almost the whole landscape of art has proved too chill, and they felt the need for a thaw, for seeing earth again. Both Dali and Picasso were trying to bring Velásquez's illusion-making genius into a new, dreamlike focus, distorting the original (as dreams do) by a breaking-up and jumbling-together process. Dali calls this "disassociation." Says Dali: "The impressionists made disassociation of light. The cubists made disassociation of forms. The surrealists made disassociation...
CHRIST walked the earth as a human being; yet for 13 centuries thereafter he was painted as a weightless, spiritual being, more in his divine aspect than in his human one. Then Giotto di Bondone, a Tuscan farmer's boy, broke the spell. He changed the course of art by proving that spirit and flesh, holiness and reality, could be pictured together as one image...
