A principle is a general belief that you have about the way you should behave , which influences your behaviour.

The principles of a particular theory or philosophy are its basic rules or laws.

one of the fundamental assumptions on which a particular theory or procedure is thought to be based

the cosmological theory that the presence of life in the universe limits the ways in which the very early universe could have evolved

the principle that bank notes are a form of credit and should be issued freely in order to maintain an elastic currency

any of various bitter-tasting substances, such as aloin , usually extracted from plants

the principle that no heat engine can be more efficient than one operating on a Carnot cycle of reversible changes

the principle that banks should be permitted to issue notes only against bullion or coin

→ Pauli exclusion principle

the principle that a ray of light passes from one point to another in such a way that the time taken is a minimum

the principle that similar species cannot coexist for long in the same ecological niche

a fundamental moral rule that guides and influences how something is done

the idea that psychological processes and actions are governed by the gratification of needs. It is seen as the governing process of the id , whereas the reality principle is the governing process of the ego

control of behaviour by the ego to meet the conditions imposed by the external world

a law of physics stating that the apparent upward force ( buoyancy ) of a body immersed in a fluid is equal to the weight of the displaced fluid

the principle that in a liquid flowing through a pipe the pressure difference that accelerates the flow when the bore changes is equal to the product of half the density times the change of the square of the speed , provided friction is negligible

the theory that the universe is uniform , homogenous , and isotropic , and therefore appears the same from any position

the principle that for a moving body the external forces are in equilibrium with the inertial forces; a generalization of Newton's third law of motion

→ the Maupertuis principle

the principle that energy and time or position and momentum of a quantum mechanical system, cannot both be accurately measured simultaneously. The product of their uncertainties is always greater than or of the order of h , where h is the Planck constant

(in the philosophy of the logical positivists) the doctrine that nontautologous statements are meaningful only if it is in principle possible to establish empirically whether they are true or false

the principle that the laws of quantum mechanics and of any new theory that may be developed reduce to the laws of Newtonian mechanics and electromagnetic theory when applied to systems in which Planck's constant can be regarded as negligible , wavelengths are comparatively small, dimensions are relatively large, etc

the requirement that a business transaction be approved by at least two individuals

→ uncertainty principle

the precept that an action should not be taken if the consequences are uncertain and potentially dangerous

the principle that if a system in chemical equilibrium is subjected to a disturbance it tends to change in a way that opposes this disturbance

the principle that two identical fermions cannot occupy the same quantum state in a body such as an atom

the ethical principle that an action is right in so far as it promotes the greatest happiness of the greatest number of those affected

→ uncertainty principle

the principle that the frequencies of lines in atomic spectra can be represented as differences of a smaller number of terms, all characteristic of the emitting system, interpreted in quantum theory as the emission of exactly one photon in a transition between energy levels

the principle that motion between any two points in a conservative dynamical system is such that the action has a minimum value with respect to all paths between the points that correspond to the same energy

any of several physical laws that the resultant of similar vector quantities at a point is a function of the sum of the individual quantities, esp. the law that the displacement at a point in a medium undergoing simple harmonic motion is equal to the sum of the displacements of each individual wave

the principle that motion between any two points in a conservative dynamical system is such that the action has a minimum value with respect to all paths between the points that correspond to the same energy

the property that for natural numbers a and b , either a is less than b , a equals b , or a is greater than b
