这是科学学一条重要规律,是普赖斯根据统计大量数据提出的。知识量指标(或科技成果、书刊出版量等)符合下式:W=ae~(βt),式中 a,β为常数,T 为年代。将上式微分 dW/dt=kW,其中 k 为常数。这证实了一百年前恩格斯揭示的“科学的发展则同前一代人遗留下的知识量成比例”的规律。我们研究科学史还表明,方法论的增长与科学发展同步。因此,方法论的增长基本上也符合指数律。 This is an important law of science, Price is put forward based on a large number of statistical data. Knowledge index (or scientific and technological achievements, publications, etc.) meet the following formula: W = ae ~ (βt), where a, β is constant, T is the age. The above equation dW / dt = kW, where k is a constant. This confirms the law of one hundred years ago that Engels revealed that “the development of science is proportional to the amount of knowledge left behind by the previous generation.” Our study of the history of science also shows that the growth of methodology coincides with the development of science. Therefore, the growth of methodology is basically in line with the exponential law.
