In today's changing world, all kinds of problems are plaguing people's thinking. Why is there a conflict between Russia and Ukraine? Why did the Soviet Union continue to expand and interfere in the internal affairs of other countries? What is the difference between Roma in Europe and Hakka in China? What impact does the change in global temperature have on the development of human society? Why did the United States lose in Vietnam and Afghanistan? This book uses the knowledge of thermodynamics to explore the problems of social systems. We can even apply the theory of social thermodynamics to the animal world to see why the polygamous societies of lions are so markedly different from the monogamous societies of wolves. By quantifying some important parameters, the social thermodynamic system can be used to analyze the relationship between social pressure, social temperature and social space, and obtain corresponding critical parameters to judge the possibility of phase transition in social systems. At the same time, the state of the social system can be judged according to entropy and free energy. The main focus of this book is sociology, so the mathematics used is relatively simple.

This book introduces the theory of virtual spacetime physics. Starting from the establishment of Maxwell equations based on virtual spacetime, the new Maxwell equations are solved step by step. And obtained a series of new and meaningful results. These results are consistent with the existing theories of quantum mechanics, quantum field theory and general relativity. Although the virtual spacetime is added, the whole theory becomes more concise. Some phenomena and problems that cannot be explained by old theories can be easily solved, and the physical picture is clearer. And just like the introduction of imaginary Numbers in mathematics, it can make some of the seemingly complicated problems in elementary mathematics very simple. The reader only needs to have the elementary knowledge of general university higher mathematics to be able to read this book, then deeply understands the current physics development the most cutting edge knowledge.
