Alternative form of Le Chatelier's principle

(programming, object-oriented programming) Alternative spelling of open-closed principle

(physics) the principle that the laws of gravity are independent of velocity and position

(physics, quantum mechanics) The principle that there is an absolute limit on the combined accuracy of certain pairs of simultaneous, related measurements, especially that of the position and momentum of a particle. Originally posited as a problem of measurement, it was soon refined as an inherent property of the universe.

(chemistry) A principle stating that, if a chemical system at equilibrium experiences a change in concentration, temperature, or total pressure, the equilibrium will shift in order to minimize that change.

(physics) The observation that the sums and differences of the frequencies of spectral lines often equal other observed frequencies; a consequence of quantum mechanics.

The axiom that "machines should work; people should think".

(physics) A principle in quantum mechanics that states that no two identical fermions may occupy the same quantum state simultaneously.

(programming, object-oriented programming) principle that states that once an interface has become too large, it needs to be split into smaller and more specific interfaces so that any client of the interface will only know about the methods that pertain to itself. (In other words: no client should be forced to depend on methods it does not use.)
