据英国学者詹姆斯.马丁统计,人类知识的倍增周期在19世纪为50年,20世纪前半叶为10年左右,到了70年代,缩短为5年,80年代末几乎已到了每3年翻一番的程度。还有报告说全球印刷信息的生产量每5年翻一番,《纽约时报》一周的信息量即相当于17世纪学者毕生所能接触到的信息量的总和。近30年来,人类生产的信息已超过过去5000年信息生产的总和。经常听到有读者抱怨信息爆炸、信息污染、对信息查找所 According to the British scholar James Martin, the multiplication cycle of human knowledge was 50 years in the 19th century, about 10 years in the first half of the 20th century, to 5 years in the 1970s, and almost doubled every 3 years in the late 1980s Degree. There is also a report that the volume of printed information produced in the world doubled every five years and that the weekly information in The New York Times corresponded to the sum of information accessible to scholars of the seventeenth century. In the past 30 years, the production of human information has surpassed the sum of the information produced in the past 5000 years. I often hear readers complain about information explosion, information pollution, information search
