It is firstly pointed out why traditional epistemology cannot accept the concept of power, so we must shift the view of knowledge and turn from representationism to know-how. Thus, essential correlations between knowledge and power will be set up. In the last part, several difficulties caused by the shift, such as the problems of rationality and relativism, are presented.

First, based on the analysis of the grid Reynold number, the necessity for adopting high order scheme is emphasized when there is the complex flows with strong separation and high parameters gradient regions. Then, according to the entropy increased condition, the third order ENN scheme is constructed. Meanwhile, a fast, effective, and simple implicit numerical method called hybrid flux splitting method is developed. After that, the one dimensional model problem with many extrema and Burgers equation are simulated. Through the comparisons with exact solutions, the accuracy and effectiveness of the ENN scheme are confirmed.
