Physics (Greek: φυσικός (physikos), "natural", and φύσις (physis), "Nature") is the science or study of nature in the broadest sense.
Studying the physics of natural phenomena that are not life or matter within the scope of space and time. Physicists study the behavior and properties of materials in the field of boiling range from submikroskopis particles that make up all matter (particle physics) to the behavior of the material Universe as a whole cosmos.
Some of the properties studied in physics is the nature of the existingin all existing material systems, such as the law of conservation of energy. Nature Such is often referred to as the laws of physics. Physics is often referred to as the "fundamental science", because every other natural sciences (biology, chemistry, geology, etc.) to learn certain types of material systems that obey the laws of physics. For example, chemistry is the science of molecules and the formation of chemical substances. Chemical properties of a substance is determined by the nature of the molecules that make it up, which can be explained by the science of physics such as quantum mechanics, thermodynamics, and electromagnetics.

History of physics began in about 2400 BC, when cultures
Harappan using an object to estimate and calculate the angle of stars in the sky. Since then physicists continue to grow to such a level now. This development does not only bring about a change in the field of world objects, mathematics and philosophy, but also, through technology, bringing change to the social world. Scientific revolution that took place occurred in about the year 1600 can be said to be a boundary between ancient thought and the birth of classical physics. And finally progressed to the year 1900 which marks the start of a new era is the era of the course of modern physics. In this era scientists do not see any improvement in science, question after question kept popping up endlessly, from the breadth of the galaxy, the nature of the environmental conditions to subatomic vacuum. List of physicists had to solve the problem which continues to grow over time.
In the early 17th century, Galileo pioneered the use of experiments to ascertain the truth of the theory of physics, which is the key to the scientific method.
Galileo formulated and successfully tested several results on the dynamics
mechanics, especially Inert Law. At 1687, Isaac Newton's Mathematical Principles of Natural Philosophy published, providing clear explanations and successful physical theories: Newton's laws of motion, which is the source of classical mechanics, and Newton's Law of Gravitation, which describes the fundamental force of gravity. Both of these theories fit within the experiment. Prinsipia also included several theories in fluid dynamics. Classical mechanics developed by the massive Joseph-Louis de Lagrange, William Rowan Hamilton, and others, are creating formulas, principles, and new results. Gravitas initiate legal field of astrophysics, which describes astronomical phenomena using physical theories.
Since the 18th century onwards, thermodynamics was developed by
Robert Boyle, Thomas Young, and many others. In 1733, Daniel Bernoulli
using statistical arguments in classical mechanics to lower thermodynamic results, initiating the field of statistical mechanics. In 1798, Benjamin Thompson demonstrated the conversion of heat into mechanical work, and in 1847 James Joule stated the law of conservation of energy, in the form of heat and energy in mechanics.
Physics research culture is different from other sciences because of the
separation of theory and experiment. Since the twentieth century, most individual physicists specializing in researching theoretical physics or experimental physics course, and in the twentieth century, few are successful in these areas. In contrast, almost all theorists in biology and chemistry is also a successful experimentalists.
Although the physics discussed diverse systems, there are several theories
used as a whole in physics, not in one area. Each theory is believed to be true, in a certain area of validity. For example, the theory of classical mechanics can explain the movement of objects by right, as long as these objects larger than atoms and moving at speeds much slower than the speed of light. These theories are still studied; example, admirable aspect of classical mechanics known as chaos theory found in the twentieth century, three centuries after formulated by Isaac Newton. However, few physicists who consider these basic theories diverge. Therefore, these theories are used as the basis for research into more specialized topics, and all the actors of physics, whatever his specialty, is expected to understand these theories.
