...potential, between clouds and earth (or be tween different clouds) to overcome the resistance of the insulating layer of air between them. The buildup occurs when electrons, perhaps carried by falling water droplets, migrate to the bottom of a cloud, giving it a strong negative charge. Because like charges repel, that negative charge drives away electrons in the ground below, leaving it with an excess positive charge. Eventually, the voltage between cloud and ground becomes so great that electrons burst across the insulating air barrier, producing a brilliant flash...
...fetus uses on the mother to increase its size and fitness while still in the womb. Even more surprising is Trivers' theory (for which he admits there is yet no evidence) of genetic conflict between egg and sperm before conception: under some conditions, the egg may try to repel sperm with female-producing X chromosomes in order to be fertilized into a boy rather than a girl...
...atomic nuclei of light elements like hydrogen collide and merge. The resulting nuclear particles contain less mass than the sum of the original nuclei; again, matter has been converted into energy. But while atomic nuclei easily split, they do not easily fuse; they have positive electric charges and thus repel each other, acting as if they had invisible springs between them. Getting them to join requires that they approach each other with enough energy to overcome their natural repulsion and smash together. Thus causing large numbers of nuclei to fuse and provide substantial energy requires three conditions: 1) very high...
...rebellion from dissatisfied factions elsewhere in the country. Although the U.S., Belgium and France have airlifted supplies to Zaïre, it is unlikely that any of Mobutu's traditional allies would try to mount a rescue operation. One reason: his crumbling, corruption-riddled army seems unable to repel the invaders...
...artist-in-residence in Tampa, Florida, where she practices her philosophy that art should be a lifestyle and strives to make art accessible. There she plans works that are on a large scale (one sculpture planned will be four stories high), but that nonetheless invite rather than repel people. Similarly, the sculptures in this exhibition manage at once to personify music with their rhythmic compositions and to feast your eyes with more substantial fare--knotty wood with the nails and lumbermarks still showing. This self-conscious structure belies the seemingly organic and hence (you might have thought) unconscious "growth...
