In statistics, a power law is a functional relationship between two quantities, where a relative change in one quantity results in a relative change in the other quantity proportional to a power of the change, independent of the initial size of those quantities: one quantity varies as a power of another. For instance, considering the area of a ...
A scale-free network is a network whose degree distribution follows a power law, at least asymptotically. That is, the fraction P (k) of nodes in the network having k connections to other nodes goes for large values of k as. where is a parameter whose value is typically in the range (wherein the second moment (scale parameter) of is infinite ...
An example of the Matthew Effect's role on social influence is an experiment by Salganik, Dodds, and Watts in which they created an experimental virtual market named MUSICLAB. In MUSICLAB, people could listen to music and choose to download the songs they enjoyed the most. The song choices were unknown songs produced by unknown bands.

From Fensham's point of view, this meant that students would engage with different viewpoints on issues concerning the impact of science and technology on everyday ...
The history of scientific method considers changes in the methodology of scientific inquiry, as distinct from the history of science itself.

[ 1 ] Power does not exclusively refer to the threat or use of force (coercion) by one actor against another, but may also be exerted through diffuse means (such as institutions).
The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, [2] is a power-law probability distribution that is used in description of social, quality control, scientific, geophysical, actuarial, and many other types of observable phenomena; the principle originally applied to describing the distribution of wealth in a society, fitting the trend ...
Educational research. Science education is the teaching and learning of science to school children, college students, or adults within the general public.
