The Research On The Complexity Of Inspection Of Natural Science

There are five human abilities to get and create knowledge:the ability to receive information of objective world through the senses,memory,imagination and logical reasoning ability or rational thinking ability. Therefore, the whole human knowledge can be divided into three types:subjective knowledge,objective knowledge and reasoning knowledge. The so-called subjective knowledge is entirely created by human imagination, such as linguistics,language,religion,art, etc. They are generally belongs to the humanities. The so-called reasoning knowledge is that deduced through logical reasoning on the basis of justice or the precise knowledge of human beings, mainly including logic and mathematics.Because of the different types of knowledge, their test methods are different too. To the scientific knowledge of nature, there are mainly two test methods:logical and empirical methods. The logical methods examine the nature science as the explanatory system or theory system of the reasons of nature phenomena, and whether it has internal logic of self-consistency, that is whether the theory has logical contradictions within the system. Empirical methods test the nature science knowledge whether'right'or agree with the experiential facts.As the nature of nature scientific knowledge is revealing the reasons behind nature phenomena, and with reasons to explain the phenomenon. So in usual cases, the experience tests of nature scientific knowledge are indirect tests, that is, according to the 'post items as true (false), and then piece is also true (false)'principle. However, 'after the piece is true (false), the latter piece is also true (false)'it has not solid foundation, coupled with the'experience fact'got from the scientific paradigm and specific historical conditions through observation and experiments certainly has many defects, so the experience of natural science test is a very complex issue.From the actual situation as well, in history of science, there are many scientific theory "confirmed" by the long-term observation and experiment was latter proved to be totally wrong; on the contrary, some correct scientific theory can't be proved at that time and then be abandoned. Similarly, we today consecrated the quantum theory, the big bang theory, general relativity, special relativity and other scientific theory and so on, but if they really reflect the real'thing', no one dare to guarantee that. This means how to understand and identify the scientific truth, it is actually a very complex issue, we must re-examine it.
