Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity. [HTTP ] Physicists study a wide range of physical phenomena spanning all length scales: from the subatomic particles from which all ordinary (i.e., baryonic) matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology).
Physics discoveries find applications throughout the other natural sciences, since it studies the basic constituents of the natural world. Some of the phenomena studied in physics, such as the conservation of energy, are common to all material systems. These are often referred to as laws of physics. Physics is sometimes said to be the "fundamental science", because each of the other natural sciences (biology, chemistry, geology, etc.) deals with particular types of material systems that obey the laws of physics. For example, chemistry is the science of molecules and the chemicals that they form in the bulk. The properties of a chemical are determined by the properties of the underlying molecules, which can be described by areas of physics such as quantum mechanics (called in this case quantum chemistry), thermodynamics, and electromagnetism.
Physics is closely related to mathematics, which provides the logical framework where physical
