Today, we are enjoying the atmosphere of contemporary science and technology and application. Science and technology are used in almost every house electronic equipment we use for entertaining and entertaining information from the house where we live, from the food we are eating, from the car we drive, Until, it is part of every human activity. All of these evidences show blessings on human scientific knowledge. Before the 18th century, we fell into the abyss of ignorance and lack of understanding of scientific knowledge.
The purpose of science is to create scientific knowledge. Scientific knowledge refers to a wide range of legal and theoretical systems used to describe interesting phenomena or behaviors obtained using scientific methods. The law is a model for observing phenomena and behaviors, and the theory is a systematic interpretation of potential phenomena and behaviors. For example, in physics, Newton's Law of Motion states what happens when an object is stationary or moving (Newton's first law), how about moving or stopping collision of a stationary object Will it be (Newton 's third law). In general, these three laws form the basis of classical mechanics - the theory of moving objects

The law of science is similar to scientific theory because it is a principle that can be used to predict the behavior of nature. Scientific law and scientific theory are often fully supported by observation and experimental evidence. In many cases, the laws of science refer to rules that appear naturally under certain conditions, usually written as equations. Scientific theory is a more comprehensive interpretation of how nature works and why it has certain characteristics. As a comparison, the theory explains why we observe what we did and the law explains what happened.
