Now the Boltzmann Formula is not well understood. The direct meaning of this formula is, entropy increasing represents the increasing number of complexion, while entropy decreasing represents the broken of symmetry. Two deductions can be made from it. First, complicating the structure is entropy decreasing, while the simplification of structure is entropy increasing. Second, in a solitary system, a complex structure is difficult to occur and easy to be destroyed. Prigogine holds that negative entropy can only come from the world outside the system, which cannot explain the evolution of the world. The state when the chemical force is zero is a steady state, not a balanced state, because the decreased entropy and complicated system may have completed. Universal gravitation, electromagnetic force, strong interaction and weak interaction can destroy the Boltzmann Formula and the Second Law of Thermodynamics. So the world will evolve forever. Every property of substance and people's intelligence may be the force that promotes the world to develop towards complication and non-equilibrium. Complicated systems have more properties than simple ones, and it is easier for them to make positive and negative feedbacks. Therefore, the evolution of complicated system is faster than simple ones.
