Laws of Conservation of Mass and Energy

Introduction Science, especially chemistry, that requires computation requires precision accuracy and accuracy to collect measurements of various physical and chemical properties. This is because the quality and value of science is manufactured or manufactured at the most important stage. Regardless of how people do the experiments, if you do not anticipate how to collect the data correctly, the information gathered will not be reliable enough to derive the conclusion. The main purpose of this experiment is to explain thoroughly the reaction system that can be achieved through scientific observation. Because, through this important step, conditions necessary for reaction can be clarified.

The first law of thermodynamics is often said to be equal to system energy as heat or work that the sum of all energies is passed to the system boundary when the system experiences the process, so often the energy conservation law Actually it is called mass energy). Net change. For example, if you do physical work (such as stirring water) on the system, energy starts to move and the rest will raise the temperature of the system. Classical physics or Newtonian physics are imperfect because they do not involve the irreversible process associated with the increase in entropy. Entropy of the whole universe always increases with time. We are just a local place with low entropy, our destiny is linked to chaotic growth that our world can not stop => stars are burned out, civilization due to lack of power die

According to the conservation law of mass and energy conservation law, the total mass of the universe + energy does not change for a certain time. Therefore, in order to move from one moment to another, it is necessary to "remove" the mass + energy at a certain moment and "create" the same amount at another moment. This is not accepted by the above law. In addition, it is very difficult to make accurate copies of corrupted content from scratch. But there is a way to solve this problem. Even if it is not "to destroy and create", we will not violate this law if we can "reform and replace" quality and energy. Let's say a scientist wants to make a (now) time machine and he needs help in the future. To do this, he has to adjust the two periods and send information from one period to another. He can not wait several years to revitalize it myself. In this case his gift (which will ultimately be his past), he will not be able to record the machine he used.
