Last week, I took part in a meeting at the Complexity Science Hub (Vienna) with other scientists to discuss the science of cities. A highlight was the presence of Geoffrey West, a leading authority on #ComplexSystems and #UrbanComplexity. #Complexity #CityScience #UrbanStudies

Validating Urban Scaling Laws through Mobile Phone Data: A Continental-Scale Analysis of Brazil's Largest Cities \abstract{Urban scaling theories posit that larger cities exhibit disproportionately higher levels of socioeconomic activity and human interactions. Yet, evidence from developing contexts (especially ...

Ontem fui assistir #AindaEstouAqui. É incrível como precisamos falar 1000 vezes mais sobre a ditadura para que as pessoas não esqueçam. Memória é resistência. 🎥✊ #DitaduraNuncaMais

I feel personally attacked by this. We don't have enough centrality scores until we can make a graph of them and figure out the central one.

The robustness of #UrbanScaling through time: Despite the chaotic "movement" of individual cities, the slope of the red straight line (across city fit) remains constant. 📈 Dive into the details in our paper:

It’s amazing how a single model can revolutionize so many fields: Physics (spin glass, Nobel Prize 2022), Neural Networks (Hopfield model, Nobel Prize 2024), and Economic Complexity. The power of universality in science! 🌍🔬 #Science #complexity

Presenting on #urbanscaling at the National Encounter on Statistical Physics! 🏙️ Exploring how cities grow, connect, and innovate through the lens of scaling laws.

Urban Scaling: Allometry in Urban Studies and Spatial Science Urban allometry empirically describes how “things”, for example crime, GDP, emissions, energy use, area, street length, housing prices, etc. change in cities when their size, in terms of population, i...
