Exploratory Comment On The Role Of Logic In The Innovation Of Physical Knowledge

Almost at the same period, in order to explain the inherent law in thinking process, then to restrain or standardize the process of human's communication and knowledge innovation, thinkers from Greek and China paid their attentions to the thought of human being. That is human being who rethinks profoundly and consciously to the thinking process, and also is a process in which logic embodies its value.From getting fire by drilling the wood to nuclear power, from Euclidean Space to Riemann Space, from description of the macroscopic and low-speeded movement in Classical Mechanics to the statistical wave functions description of microscopic and high-speeded movement in Quantum Mechanics, the innovation progress of Physics is just as always. The history of Physics is an innovation history, where we unceasingly discover phenomenon and uncover new laws and establish new theories.The dissertation analyzes the roles of logic in the innovation of Physical theory by three aspects. That is logic with Physical discovery and logic with the testing to Physical theory and logic with innovation of Physical theory.In the development process of Physical theory, physical discovery is the beginning and the end of the spiral rise, and also is the hinge of the innovation of Physical theory. Physical discovery has its inherent logic, and is not a simple inspiration or a single induction and deduction. Logic takes a very important role in the Physical discovery. It mainly reflects in two aspects: Analogical reasoning pushes the discovery of physics forward and the enlightening function of ideal experiments.The progress of the physical discovery is not reasoning thoroughly. In order to acquiring a correct and reliable Physical theory, we should test the theory. By the testing, people always want to get two kinds of result: confirmation and falsification. In sufficient conditions hypothetical judgment, the justification of consequent cannot lead to the justification of antecedent, and the falsification of consequent cannot lead to the falsification of one of the condition in the antecedent set. After having these logic rules and principle in hand sufficiently, people can get a further understanding of the complicated theory testing process and deepen the testing of physical theory.It put forward further development of physics by revising and incorporating the concrete theory, which is get from testing and have a very high reliability. Making a general observation of innovation of Physics theory, we may find the innovation is always follows such way: by the preliminary observation and experiment, bringing forward some trial hypothesis, then amend these hypothesis and make them more close to the nature things and confirm these reliable theory. It is inevitably to systematize the theory of Physics, while they have been accumulated a lot number of concepts, laws and principles. During this period, hypothesis is the most important form to innovate the theory of Physics. From the raising of the hypothesis to revisal, and then the raising of new theory, the pattern becomes the inherent logic of the innovation to theory of Physics.
