Life is minimize the entropy.

Life is minimize the entropy. a great life is doing so in the most effective way.

let me first define this physical term again: the entropy is a measure of the the unavailability of a system’s energy to do work. 

seem complicated. the entropy is just like saturated fat, which is the unavailabe fat for our body to release energy, to do work. so, we should minimize it, right? 

however, entropy is not that simple and naive. we found that while the unavailable energy (or waste energy) in a system is lower, the system become well oranginzed. 

a very easy understand example is a system of dice. lets take an example of 3 dice. the dice can be completely random, like (1,3,6) or completely in order, like (1,1,1). we found that the entropy of the system is very related to the posibility. in the case (1,3,6), the possiblilty is (1/6)^3 times the combination of (1,3,6), which is 6, there are 6 different way to arrange them. so the posibility is 1/36. but in the case (1,1,1) the possibility is 1/216, since the combination of (1,1,1) is 1, there is only 1 way to arrange them. so, the well ordered system has lower entropy then the disorder system.

ok, i hope we now can see the "order" and entropy is related. time to look the nature. a hot gas, of course, is full of entropy, a lot un-useable energy. how about an ice?? it is a crystal, the water molecule stay close to each other, so, this system is more ordered. however, a living cell?? a living cell is very well ordered. it needs a membrance, a close pack of fat molecule to protect the little factory inside. how about human? of course, we are super-ordered. every part of our body need to coordinate to each other, to support our life. we eat food, because we need energy to remove the "saturated fat", keep us orgainezed. and the reason for getting old, is , we are going to disorder. 

well, we just talk about the biological aspect of order. how about our behaviour??? if we don't have order in life, what will happen? we will feel bad, and choas. we cannot do anything, in case of extreme. just think about if there is no traffic light, no pedestrian side, it is almost too dangerous to drive a car or walk on the street. so, we need order in our life. 

everyone must have certain degree of order, or discipline. but if we want to checkmate , want to do something great, rather than fulfil little goals. we have to be super organized and had the power to initialiating ourselve to plan and keep on schudle.
