Forcing
Encyclopedia
Forcing may refer to:
- Forcing (set theory), a technique for obtaining proofs in set theory
- Forcing (recursion theory)Forcing (recursion theory)Forcing in recursion theory is a modification of Paul Cohen's original set theoretic technique of forcing to deal with the effective concerns in recursion theory. Conceptually the two techniques are quite similar, in both one attempts to build generic objects by meeting dense sets...
- Radiative forcingRadiative forcingIn climate science, radiative forcing is generally defined as the change in net irradiance between different layers of the atmosphere. Typically, radiative forcing is quantified at the tropopause in units of watts per square meter. A positive forcing tends to warm the system, while a negative...
, the difference between the incoming radiation energy and the outgoing radiation energy in a given climate system - Cloud forcingCloud forcingCloud forcing is, in meteorology, the difference between the radiation budget components for average cloud conditions and cloud-free conditions...
, the difference between the radiation budget components for average cloud conditions and cloud-free conditions - Forcing (magic), a technique by which a magician forces one outcome from a card draw
- Forcing, driving a harmonic oscillatorHarmonic oscillatorIn classical mechanics, a harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F, proportional to the displacement, x: \vec F = -k \vec x \, where k is a positive constant....
