“Physicists are very good and famous for getting the right answers for the wrong reasons.” Why? Here’s a clue: noisy philosophizing!

We should switch from paper to screen posters—more eco-friendly and far more engaging. Elisa’s poster already showed us how creative this can be.

What if #herd_immunity isn’t just about how many people are immune, but how they’re 'spatially' connected? Our new PNAS paper explores this concept. We show how the topology and geometry of social networks influence the dynamics of herd immunity, whether it arises from infection or #vaccination. 1/2

What is #emergence, after all?

We unpack its meaning across science & philosophy, drawing on examples ranging from physics to bird flocking & epidemics. We feature how #herd_immunity emerges as immune individuals form overlapping firewalls that grow into a dominant shield.

@sunelehmann.com got me thinking:
Are there things that will always remain beyond human understanding, but not for AI? Is there a cognitive upper bound for us—due to our biology—much like a cat can't grasp the mathematics of spacetime curvature?
Oh, and the reference totally sealed the deal 😄

Cool hypergraph approach for modeling homophily explicitly at each interaction size! Samantha told us how shifting homophily across hyperedge sizes can amplify inequality in who gets timely information—a perfect hypergraph companion to our clique-layer story. arxiv.org/abs/2412.07901 #netsci2025

Walk down the street of any city, and look around you. What you've got to remember is what you're looking at is also you. Everyone you're looking at is also you. You could be that person. You could be that monster, you could be that cop. And you have to decide, in yourself, not to be.

F: I never catch colds.

F: I was reading some sickness and accident claims figures. The average New Yorker aged between 20 and 50 has two and a half colds a year.
B: That makes me feel just terrible.
F: Why?
B: If I have no colds a year, some poor slob must have five colds a year.
