(Inside Science) People walking alone walk relatively quickly. A crowd walks slowly. But how does a crowd move when there is, say, a massive bull charging at them? To answer this, scientists analyzed the movement of a crowd of runners during the running of the bulls in Pamplona, Spain, in 2019.
The San Fermín festival in Pamplona, Spain, hosts the world's best-known running with bulls event. Every morning for a week each year, festival officials send six bulls charging down a set of narrow, blocked-off streets toward waiting crowds of people.
