Measuring social interactions is a challenge. In our online game 2peeornot2pee.com, we explore the unwritten rules of public urinal use. From these choices, we infer repulsive social interactions—useful to model behavior in public spaces. Play the game and contribute to science!

The poster session at #STATPHYS29 was a fantastic experience! Our GRASP team (University of Liège – www.grasp.uliege.be) presented real-time experiments, which generated a lot of interest. We’re grateful for the valuable feedback and inspiring discussions with colleagues from across the globe.

After my talk at #STATPHYS29, we demoed our robotic platform GRASPion.be for active matter.
Great interactions, promising perspectives for GRASP’s ongoing projects.
Thanks to the GRASP.uliege.be team for the brilliant work!
