As a parallel experiment of innovation involving economic, historical and social components, artifacts define a universe of evolving properties that displays episodes of diversification and extinction. Here we critically review previous work… (More)
Computers have expanded the range of nonlinear phenomena that can be explored mathematically. An “experimental mathematics facility,” containing both special-purpose dedicated machines and general-purpose mainframes, may someday provide the ideal context for complex nonlinear problems.
