What Happens at WorldCon Stays at WorldCon (2026 Edition)

I am heading to Anaheim for the 2026 WorldCon, where I will be on various panels and otherwise geek out to science fiction and related things.

Dodgers Acquire Ace Pitcher Tarik Skubal

Yesterday, the Dodgers continued being the Evil Empire by making a trade with the Detroit Tigers for ace pitcher Tarik Skubal, who is expected to be the top prize of this season's trading market. The Dodgers didn't even have to give up that many top prospects to do it, as their farm system is loaded. When it comes to the Dodgers, it's 'Moneyball' with money. Let's see if they can become the first ever National League team to win three World Series in a row!

"Long-Time and Short-Time Dynamics in a Weighted-Median Opinion Model on Networks"

One of my papers was published in final form late last month. Here are some details.

Title: Long-Time and Short-Time Dynamics in a Weighted-Median Opinion Model on Networks

Authors: Lasse Mohr, Poul G. Hjorth, and Mason A. Porter

Abstract: Social interactions influence people's opinions. In some situations, these interactions eventually yield a consensus opinion; in others, they can lead to opinion fragmentation and the formation of different opinion groups in the form of "echo chambers". Consider a social network of individuals with continuous-valued scalar opinions, and suppose that they can change their opinions when they interact with each other. In many models of the opinion dynamics of individuals in a network, it is common for opinion updates to depend on the mean opinion of interacting individuals. As an alternative, which may be more realistic in some situations, we study an opinion model with an opinion-update rule that depends on the weighted median of the opinions of interacting individuals. Through numerical simulations of our median-update opinion model, we investigate how the final opinion distribution depends on network structure. For configuration-model networks, we derive a mean-field approximation of the asymptotic dynamics of the opinion distribution when there are infinitely many individuals. We numerically investigate its accuracy for short-time opinion dynamics on various networks.

What Happens in Boston Stays in Boston

I am off to Boston to speak in the satellite conference on Physical Networks at the 2026 NetSci conference. (It's my triumphant return to NetSci!) As usual, I also helped organize the satellite conference on Network Science in Education (NetSciEd 2026).
