The second law of thermodynamics is ubiquitous, which can explain many phenomena from the ink diffusion in the water and the heat conduction from the hot to the cold etc. Or simply put, order is always decreasing in nature. Even an ancient Chinese philosopher, Laozi once said “ It is the nature’s law nature's law to decreases those who have more than they need and increases those who need more than they have. it is not so with man. Man decreases those who need more than they have and increases those who have more than they need”. It seemed that nature always destroys the order and evens out everything in the world. Then how could life maintain its order? Why life is so unique? What are the differences between the matters with life and without? Order is important for life because losing order of life means that the atoms made of life will mix up with others in the universe. It is nothing but death.
