Why Pedestrians Do Not Constantly Collide: 2021 Ig Informal Lecture

The Ig Nobel Prizes honor achievements that make people LAUGH, then THINK.

In the Ig Informal Lectures, some days after the ceremony, the new Ig Nobel Prize winners attempt to explain what they did, and why they did it. We are releasing these lectures one at a time.

The 2021 Ig Nobel for Physics was awarded to Alessandro Corbetta, Jasper Meeusen, Chung-min Lee, Roberto Benzi, and Federico Toschi, for conducting experiments to learn why pedestrians do not constantly collide with other pedestrians.
