Scaling laws

scaling laws

(Science: radiobiology) These are mathematical rules explaining how variation in one quantity affects variations in other quantities.

For instance, in a tokamak reactor its generally believed that energy confinement depends on the size of the device and the strength of the magnetic field, but the precise nature of the dependence is not fully understood, so empirical scaling laws are tested to see what the dependence is.

scaling laws are useful for extrapolating from parameter regimes where the mathematical relationships between the various quantities are known, into unexplored regimes.
