The assay argues that the Equality-Inequality dialectics is a very complex issue,which reflects many social dilemmas.On one side are the state official commitments to secure,maintain and protect all kinds of formal equalities.On the other side are the natural and genetic distinctions that differ between human-beings while creating and maintaining inequality.In fact,this is kind of a contradiction exists in many fields of social sciences.The essay’s author reviews some of the relevant historical events,such as social mobility,individualism and education and points out on future solutions.Among the proposed suggestions are:1)Embracing Frankl’s giving“Meaning to Life”as a leverage for increasing pleasure of life;2)Recognizing and promoting Creative Individualism as the legitimized ground for inequality;3)Increasing Social Cohesion,required for social empowerment and attaining security and happiness. 展开更多

It is well known that for almost all real number x, the geometric mean of the first n digits di(x) in the Lüroth expansion of x converges to a number K0 as n→∞. On the other hand, for almost all x, the arithmetric mean of the first n Lüroth expansion digits di(x) approaches infinity as n→∞. There is a sequence of refinements of the AM-GM inequality, Maclaurin's inequalities, relating the 1/k-th powers of the k-th elementary symmetric means of n numbers for 1≤k≤n. In this paper, we investigate what happens to the means of Lüroth expansion digits in the limit as one moves f(n) steps away from either extreme. We prove sufficient conditions on f(n) to ensure divergence when one moves away from the arithmetic mean and convergence when one moves f(n) steps away from geometric mean. 展开更多
