Social Synergetics, Social Physics and Research of Fundamental Laws in Social Complex Systems
Yi-Fang Chang
We proposed social synergetics and the four basic theorems, in which theorem of perfect correlation on humanity is researched mathematically. Generally, we discuss the four variabl…
Moderate Degree of Input Negative Entropy Flow and Decrease of Entropy in Astrophysics, Biology, Psychology and Social Systems
Yi-Fang Chang
Thermodynamics have been applied to astronomy, biology, psychology, some social systems and so on. But, various evolutions from astronomy to biology and social systems cannot be on…
Unified Equations of Boson and Fermion at High Energy and Some Unifications in Particle Physics
Yi-Fang Chang
We suggest some possible approaches of the unified equations of boson and fermion, which correspond to the unified statistics at high energy. A. The spin terms of equations can be…
Ten Puzzles in Particle Theory and Quarks as Only Possible Magic Particles with Some Symmetries
Yi-Fang Chang
We propose ten puzzles in particle theory: quark, asymmetries of quantum numbers in the Standard Model, point particle and interaction-distance, mystic Higgs mechanism, possible vi…
Y-Q and I-U Symmetries, and New Unified Lifetime Formulas of Hadrons
Yi-Fang Chang
Based on the Y-Q and I-U symmetries between mass and lifetime on the general SU(3) theory, we can derive the lifetime formulas of hyperons and mesons, which agree better with exper…
Quantitative Calculations of Decrease of Entropy in Thermodynamics of Microstructure and Sufficient-Necessary Condition of Decrease of Entropy in Isolated System
Yi-Fang Chang
Firstly, we calculate quantitatively decrease of entropy by the known formulas in the ordering phenomena and nucleation of thermodynamics of microstructure. They show again that a…
