This glossary of physics is a list of definitions of terms and concepts relevant to physics, its sub-disciplines, and related fields, including mechanics, materials science, nuclear physics, particle physics, and thermodynamics. For more inclusive glossaries concerning related fields of science and technology, see Glossary of chemistry terms ...
This is a glossary for the terminology often encountered in undergraduate quantum mechanics courses. Cautions: Different authors may have different definitions for the same term. The discussions are restricted to Schrödinger picture and non-relativistic quantum mechanics. Notation: | - position eigenstate
G {\displaystyle G} electrical conductance. siemens (S) universal gravitational constant. newton meter squared per kilogram squared (N⋅m 2 /kg 2 ) shear modulus. pascal (Pa) or newton per square meter (N/m 2 ) g {\displaystyle \mathbf {g} } acceleration due to gravity.
This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of Earth. The field of astronomy features an extensive vocabulary and a ...
Classical physics is considered the limit of quantum mechanics for a large number of particles. On the other hand, classic mechanics is derived from relativistic mechanics. For example, in many formulations from special relativity, a correction factor (v/c) 2 appears, where v is the velocity of the object and c is the speed of light.
Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms. [2] : 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science . Quantum mechanics can describe many systems that ...
Glossary of quantum philosophy. This is a glossary for the terminology applied in the foundations of quantum mechanics and quantum metaphysics, collectively called quantum philosophy, a subfield of philosophy of physics . Note that this is a highly debated field, hence different researchers may have different definitions on the terms.
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics.
