PERSON
Geoffrey West
The theoretical physicist who turned the mathematics of biological metabolism into a universal theory of cities, companies, and the pace of life—revealing that the same scaling laws governing a mouse and an elephant govern a startup and a megacity, and that AI has changed the metabolic rate of every organization it touches.
Geoffrey West began his career measuring the forces that govern quarks and gluons. He ended up measuring why companies die and cities do not. The pivot happened when he encountered an obscure 1932 graph by Max Kleiber showing that metabolic rate scales with body mass to the three-quarter power across every animal on earth—and recognized it not as a biological curiosity but as a signature of something deeper. Working at the
Santa Fe Institute, West and colleagues derived Kleiber's law from first principles: any space-filling fractal network delivering resources to invariant terminal units must scale to the three-quarter power. The mathematics of biology became a mathematics of everything.
Cities scale superlinearly—doubling population yields more than double the wages, patents, and crime—while companies and organisms scale sublinearly, accruing efficiency on the path to inevitable death. The
scaling exponent is the destiny of every
