The Pace of Life (Scaling)

In 2006, Marc Bornstein's team measured pedestrian walking speeds across thirty-one cities on multiple continents. The finding was clean: people in larger cities walk faster. Not because they are in better physical condition, but because the city itself is faster. Subsequent research by West, Bettencourt, and colleagues incorporated this finding into a broader pattern. Walking speed was not an anomaly. The rate of economic transactions increases with city size. The speed of speech increases. The average duration of phone calls decreases. Patent production per capita accelerates. So does the rate of innovation, the turnover of businesses, the spread of ideas and infectious diseases alike. Everything moves faster in a bigger city — and the acceleration follows the same superlinear power law with exponent approximately 1.15 that governs economic output. The pace is not a cultural choice; it is a structural consequence of network density. This is the mathematical formalization of what Byung-Chul Han diagnosed as Rastlosigkeit — the
