Crowds of people heading in different directions meet at pedestrian crossings, stations and stadiums. Just like particles of matter in colloids or substances in some cells, these people spontaneously form traffic lanes. Researchers from Poland and the UK have just described the mathematical rules of this unusual dance in a publication in Science.
Heat islands that form in cities can be dangerous for many, especially when combined with heat waves. To check how climate change affects cities, the Polish Space Agency commissioned a heat island analysis for five large Polish cities, Jolanta Orlińska from POLSA told PAP. Understanding this phenomenon will help make life easier for residents on hot days.
