Science

Science is the overall system of human knowledge acquired by observation of processes and phenomena in nature and society. Processed as rational, scientifically acceptable methods. It is an objective, systematized and argumentative knowledge of the laws, facts, phenomena and their probable causes. Verified by observation, experiment and correct thinking. It is not just a collection of knowledge. Also a way of thinking and seeing reality, based on reason, logic, criticism, doubt, objective, free and independent thinking. It is also an objective, systematic, logical, precise and verifiable method. This is about collecting, describing, classifying, defining, measuring, experimenting, explaining and evaluating empirical fact. It's main characteristics are objectivity, systematization, argumentation or verifiablity, logic and precision.

Branches of Science

Some of the branches are astronomy, mathematics, physics, quantum physics, technology, biology, chemistry, geology and neuroscience. Some fields of science see nature as matter in motion, obeying certain laws of nature. For this reason the most fundamental science is generally understood to be physics (knowledge of nature).

In fact, physics is a natural science that deals with movement, energy and matter. Through theory, physicists are doing experiments. Experiments are investigate phenomena, a theory describing the physical phenomena in a simplified mathematical models. Laws are expressed in mathematical form. To clarify, experiments give results through measurements and comparisons with the results of the count given by the theory. The theory most well anticipated results of experiments in a wider area and makes the laws of physics. Laws are subject to change and restrictions if a later more accurate and more extensive experiments show that this is necessary. The goal is to find the laws that describe the substance, motion and energy of the tiny microscopic subatomic level, to large macroscopic level. 

The foundations of physics laid the Isaac Newton and Galileo Galilei discovering the laws of mechanics in the 16th and 17th centuries. There are several types such as classical, the theory of relativity, quantum, mechanics, thermodynamics, nuclear and other branches of physics.
