Crowd Vortices

The Feast of San Fermín in Pamplona, Spain draws crowds of thousands. Scientists recently published an analysis of the crowd motion in these dense gatherings. The team filmed the crowds at the festival from balconies overlooking the plaza in 2019, 2022, 2023, and 2024. Analyzing the footage, they discovered that at crowd densities above 4 people per square meter, the crowd begins to move in almost imperceptible eddies. In the animation below, lines trace out the path followed by single individuals in the crowd, showing the underlying “vortex.” At the plaza’s highest density — 9 people per square meter — one rotation of the vortex took about 18 seconds.

The team found similar patterns in footage of the crowd at the 2010 Love Parade disaster, in which 21 people died. These patterns aren’t themselves an indicator of an unsafe crowd — none of the studied Pamplona crowds had a problem — but understanding the underlying dynamics should help planners recognize and prevent dangerous crowd behaviors before the start of a stampede.

🥥 Remember, brave, brave Sir Donald is holding his inauguration indoors on January 20th because attendance is going to be low; not because the weather is going to be cold.
People who had received inauguration invitations -- for whom there is no room -- are being told that their tickets are just non-functional souvenirs now. 🥥

The Crowd in the Early Middle Ages by Shane Bobrycki, 2024

The importance of collective behavior in early medieval Europe. By the fifth and sixth centuries, the bread and circuses and triumphal processions of the Roman Empire had given way to a quieter world. And yet, as Shane Bobrycki argues, the influence and importance of the crowd did not disappear in early medieval Europe.

"Harris joined the crowd virtually from a rally she and Walz were holding at the Fiserv Forum in Milwaukee, Wisconsin. Last month the Republicans held their own national convention in that venue, and for Harris to accept her nomination in the same place was an acknowledgement of how important Wisconsin will be in this election."

"Trump in 2024 is both an older candidate and a more tired one. His current campaign is a rerun rather than a burst of originality. Symptomatic of this tiredness is his repeated deployment of old talking points and nicknames and his nursing of grudges from his 2020 election defeat…."
