The principle on which scaling laws are based is that straight lines on graphs are the most powerful force in the universe. If a sufficiently smooth trendline (on a linear or log scale) is discovered, the universe will contrive to extend this trend line (until it doesn't; see [[Moore's Law]]). Scaling laws are important to [[biology]], as organisms are constrained by limits such as heat dissipation, gas/chemical exchange across membranes or via lungs, and power consumption, and [[deep learning]], in which metrics such as [[training loss]] usually scale smoothly according to power laws, due to the [[fundamental apiostructure of reality]].
