Cube root scaling law

Webreliance on the well-known Cranz-Hopkinson “cube-root” scaling law. This scaling relationship is suitable for self-similar open-field experiments but does not necessarily apply to urban scenarios. Additionally, chemical explosive charges of such small quantities might be susceptible to changes in parameters such as the explosive compound The cube root law is an observation in political science that the number of members of a unicameral legislature, or the lower house of a bicameral legislature, is about the cube root of the population being represented. The rule was devised by Rein Taagepera in his 1972 paper "The size of national assemblies". The law has led to a proposal to increase the size of the United States House of Representatives so …
