Physical information Physical information Physical information is a form of information. In physics, it refers to the information of a physical system. Physical information is an important concept used in a number of fields of study in physics. For example, in quantum mechanics, the form of physical information known as quantum information is used in many descriptions of quantum phenomena, such as quantum observation, quantum entanglement and the causal relationship between quantum objects that carry out either or both close and long-range interactions with one another. In a somewhat general sense, the information of a given entity can be interpreted as its
Physics in the medieval Islamic world physics from the Greeks and during the Islamic Golden Age developed it further, especially placing emphasis on observation and "a priori" reasoning, developing early forms of the scientific method. With Aristotelian physics, physics was seen as lower than demonstrative mathematical sciences, but in terms of a larger theory of knowledge, physics was higher than astronomy; many of whose principles derive from physics and metaphysics. The primary subject of physics, according to Aristotle, was motion or change; there were three factors involved with this change, underlying thing, privation, and form. In his "Metaphysics", Aristotle believed that the "Unmoved Mover" was responsible
