For example, the weight of an object may be operationally defined by describing the operations of using a balance and standard weights. (Note that it is not the specific weight of the specific object which is operationally defined, but the process for arriving at it.his is especially so in the sciences, where most (if not all) formal definitions (as distinct from arbitrary naming) must be operational definitions or traceable to operational definitions. Operational definitions are particularly important in the physical sciences.

Rooftop sightings in the Clinton section of Manhattan on a recent morning: one plastic great horned owl at 402 West 46th Street, no pigeons; one plastic great horned owl at 503 West 47th Street, no pigeons; two plastic great horned owls, not courting, at 461 West 47th Street, no pigeons.he theory is simple: Owls prey on pigeons and pigeons are not the smartest things on wings. Confronted with something that looks like an owl, a pigeon will assume the worst and fly away. The ruse is hardly new.
