| Just as a "demographic explosion" gives much trouble to sociologists and economists, the problem of an "information explosion" is in the face of scientists and teachers in all its magnitude. The differece between both problems is in fact that the birth-rate of the population can be limited much more easily than the birth-rate of articles. Only the editors of scientific journals dream about the Golden Age when authors themselves would critivize their own works and reject all of them except brilliant ones. The birth of an article which represents even a small stemp forward frome the generally accepted level of knowledge gives a satisfaction and a pleasure which the author cannot overcome. In our opinion, one should not try to fight against the "information explosion", but rather try to direct its energy, i.e. efforts of the huge army of sentists, into a common channel. 本书为英文版。 |
