Home > Power law

where a (the constant of proportionality) and k (the exponent of the power law) are constants.

Examples of power law relationships:

• The Stefan-Boltzmann law
• The inverse-square law of Newtonian gravity
• Gamma correction relating light intensity with voltage

Examples of power law probability distributions:

• Pareto distribution
• Zipf's law

Power laws are among the most frequent scaling law s that describe the scaling invariance found in many natural phenomena.

Power setAbstract algebra Algebra Set theory In mathematics, given a set S the power set of S written P ''S or 2''S is the set of all subsets of S''. In formal language, the existence of power set of any set is presupposed by the axiom of power set. In this case S PowerGamePowerGame is a free role-playing game that been written and developed by Mikko Kauppinen since 1994. It is a free game that has a large international following and a growing reputation for being fast, fun and no more complex than it needs to be. It comes Power (physics)Mechanical power In physics, power (symbol: P is the amount of work W done per unit of time t''. This can be modeled as an energy flow, equivalent to the rate of change of the energy in a system, or the time rate of doing work, as defined by : where P is PowerPCPowerPC is a RISC microprocessor architecture created by the 1991 Apple- IBM- Motorola alliance, known as AIM''. The PowerPC was the CPU portion of the overall AIM platform, and is the only part to exist to date. History The history of the PowerPC begins Power lawIn physics, a power law relationship between two scalar quantities x and y is any such that the relationship can be written as : where a (the constant of proportionality) and k (the exponent of the power law) are constants.
