...greenhouse which sunlight kept normally at a temperature of 85°, the plant had stood inert for five years in a box of earth four feet square. Three new leaves appeared but quickly withered and died. After this came a sprout which The Bronx scientists rightly took as a sign that the monster was about to bloom at last. By last week the spadix, a yellow central spike, was 6 ft. 1½ in. long and thick as a telephone pole at its base. In, the final 24 hr. of its rise it grew one inch. The whole plant...
Looking toward the time when Earth's supply of coal & oil gives out, imaginative scientists have long tinkered with ponderous reflectors and batteries of photoelectric cells to harness the sun's outpouring of energy. Lately they have realized that plants are better converters of this energy than any man has ever devised. Ordinary cornstalks, ground to powder, can be used as a furnace fuel, like powdered coal. The Cabot researchers will try to develop bigger, more vigorous and faster-growing trees by artificial pollination and juggling of chromosomes (heredity elements in the germ cells). After 50 years...
Another factor affecting totality duration is that the shadow travels slowest at noon, fastest near the beginning and end of the eclipse day. Earth rotates eastward at about 1,040 m.p.h. at the Equator. The moon's eastward orbit carries the lunar shadow in the same direction at just about twice that speed, so that it rapidly overtakes the terrestrial rotation. At noon, when the shadow is perpendicular, the speed is 1,060 m.p.h.; earlier and later, when the cone of darkness impinges at an angle, it goes faster-depending on the acuteness of the angle...
...rocket is now in that most interesting period of discovery where the shorelines are unplotted and the future limited only by imagination. . . . As the airplane gave man freedom from the earth, the rocket offers him freedom from the air. From the standpoint of science, the rocket offers the only known possibility of sending instruments to altitudes above those reached by sounding balloons. . . . From the standpoint of commerce, we must look to the rocket if we hope to attain speeds of transport above a few hundred miles an hour. . . . From the standpoint of war, we must consider the fact that rockets...
Utopianizing, as every Wellsian knows, is H. G. Wells s crowning glory or besetting sin. In Star-Begotten his Utopian agents are extraterrestrial. The Martians know much more than Earth-dwellers but inhabit a nearly worn-out planet, have got to have greener pastures. Their attempt to Martianize the Earth at long distance is thus not wholly unselfish, but neither is it necessarily sinister. "This is a world where lots of us live upon terms of sentimental indulgence towards cats, dogs, monkeys, horses, cows, and suchlike inhuman creatures, help them in a myriad simple troubles, and attribute the most charming...
