Imagine this,a rock flies up the air while cooling down,a projectile accelerating while losing heat.We never see this kind of phenomena happening even though it is follows the 1st law of thermodynamics,that energy mya be converted from one form to another without loss.However,the second law of thermodynamics states that entropy is one-way(ie. we cannot decrease entropy without an increase in it locally of a greater magnitude)As we can see, the amount of usable energy deceases at an accelertaing rate.The random movement of molecules can't be ordered up in a single direction,therefore decresing entropy and increasing the amount of usable energy.thermal energy,however convert entropy(heat) in to usable energy but in the process create more heat that are dissapated.(ie:increase of entropy of greater magnitude then the decrease).We,human beings,strive to create order by erecting structures,acquring knowledge,etc.However,the world is thrown more and more into disarray the more we try to create order.A person who try to create order in his thoughts by studying will cause

him to think more,futher creatung disorder in our thoughts.What is the point then,of creating order?(ie: answers lead to more questions)

By creating more "order", for example constructing a building, we are actually increasing the net entropy of the universe. The process of erecting the builing with the use of people and machines creates a huge amount of disorder in the environment. For example, cellular respiration used to acquire energy for builiding releases heat into the air. This causes more disorder, and therefore increases entropy. The net entropy of a process is always positive.
