In quantum mechanics, a complete set of commuting observables (CSCO) is a set of commuting operators whose common eigenvectors can be used as a basis...

A phenomenon (pl. phenomena), sometimes spelled phaenomenon, is an observable event. The term came into its modern philosophical usage through Immanuel...

programming languages. ReactiveX is an API for asynchronous programming with observable streams. Asynchronous programming allows programmers to call functions...

different situations, depending on whether every sequential state is observable or not, and whether the system is to be adjusted on the basis of observations...

metaphysics. A Ramsey sentence aims at rendering propositions containing non-observable theoretical terms (terms employed by a theoretical language) clear by...

sphere, causal sphere and sphere of causality is a spherical region of the observable universe surrounding an observer beyond which objects recede from that...

theories. For this role, evidence must be public and uncontroversial, like observable physical objects or events and unlike private mental states, so that evidence...
