In cellular automata, simple rules create elaborate structures. Now researchers are working backward — starting with the result to learn the rules behind it. @georgemusser.com, SFI’s 2025 Journalism Fellow, explores how this could reshape computation and self-organization in Quanta:

Major European cities at the same scale. I to Melbourne (Australia) 18 years ago from Berlin. You can squeeze Berlin around seven times into Melbourne. Density matters. In a low density beast like Melbourne residents pay for much more infrastructure per head. Expensive exercise. HT @xruiztru

Looks more complicated than it is. In our recent study journals.plos.org/plosone/arti... we search for an optimum city size, minimizing both urban carbon emissions and urban heat island (constraint: fundamental allometry). It turns out that given the known UHI parameters such optimum does not exist.
