Description:This book presents and discusses an in-depth study of one dot by using different approaches and methods in social science. Since one-dot is a theory, it must be accompanied by a model, and the name of the model is called the crab and frog motion. Arguably, everything can be simplified or compressed in terms of a dot. It is suggested that the Yin and Yang diagram and three others should be applied in order to describe and explain each case study.
