Word Origin and History for observable
c.1600, from Latin observabilis "remarkable, observable," from observare (see observe). Related: Observably; observability.
- A measurable property of a physical system, such as mass or momentum. In quantum mechanics, observables correspond to mathematical operators used in the calculation of measurable quantities. Operators that do not commute, having a nonzero commutator, correspond to observables that cannot be precisely measured at the same time, such as momentum and position. See also uncertainty principle.
