a module for making square and hexagonal lattices
This explorable illustrates a simple model for pedestrian dynamics. The model can explain spontaneous lane formation in opposing flows, congestion patterns, and phenomena like crowd turbulence.
This explorable illustrates dynamic patterns that emerge when collective motion and synchronization interact in a swarm of phase coupled oscillators.
This explorable illustrates a model for traffic and congestion and the phenomenon knowns as phantom traffic jams, spontaneously emergent congested traffic segments that move slowly and oppositely to the traffic.
This explorable illustrates the basic mechanism of evolution. In a population of replicating species, species with the highest fitness dominate until mutations yield yet more fit species. The fitness of the entire population increases steadily.
This explorable illustrates oscillatory dynamics and spatio-temporal patterns in the most famous predator prey model on a lattice.
This explorable illustrates a famous game theoretic model, known as the prisoner's dilemma. On a lattice it can yield beautiful patterns and chaos.
This explorable illustrates a model for fractal growth patterns in natural systems based on the aggregation of randomly moving particles.
This explorable illustrates, as a representative of a broad range of dynamic phenomena, a simple model for the spatial spread of forest fires and the dynamic patterns they generate.
A collection of regular fractals that illustrates the nature of self-similarity
This is a model for collective behavior in animals, e.g. flocks of birds or schools of fish based on simple rules of interaction.
The explorable illustrates the behavior of a contagion process, like an epidemic. Susceptibles (S) can be infected by other infected sites (I), infected site become immune and recover (R), and when immunity wanes immune sites become susceptible again.
Dieses explorable zeigt ein einfaches Verkehrsmodell, das in der Lage ist die spontane Entstehung von sogenannt Phantomstaus zu beschreiben, die sich entgegen der Verkehrsrichtung ausbreiten, wenn die Zielgeschwindigkeiten einzelener Verkehrsteilnehmer gr
This explorable illustrates the emergence of collective intelligence in a model for a school of fish. The combination of speed differences in the light and the dark and cohesive swarm forces helps the swarm find the safe regions.
The XY model is a key model of statistical mechanics. Among other things, it describes self-organization of spatially arranged magnets but also concepts like opinion dynamics in social systems.
This explorable illustrates the phenomenon of percolation, when e.g. a liquid like water moves through a porous medium, like coffee. The percolation process is a critical phenomenon that exhibits interesting properties at the critical porosity of the medi
The explorable illustrates the properties of superdiffusive, scale-free random walks known as Lévy flights.
The explorable illustrates spatio-temporal pattern formation in a system of pulse-coupled oscillators. The model is a generic model that yields spiral waves and target patterns depending on the parameter choices.
This explorable illustrates the beauty of strange attractors of selected two-dimensional chaotic maps. The attractors change shape as a function of their parameters.
This explorable illustrates the dynamics and properties of the famous Ising Model of statistical mechanics. It's a lattice of spins / magnets arranged on a lattice. Each spin interacts with its neighbors and tried to align its direction with the neighborh
