摘要

Since the twentieth century scientific developments have carried man's knowledge about nature further into macroscopic and microscopic worlds. Meanwhile, man's interference with mature has obviously increased. In social life, while science displays beneficial social functions, it brings about certain harmful results to society as well. Therefore, progress in natural sciences no longer means only the gain to knowledge of nature and reform in nature, it is also confronted with various kinds of social problems caused by nature's antagonism against human society and the necessity to find solution to those problems. Because of that, scientists, one after another, start to work into the overlapping areas of traditional scientific branches.
