# How to Model Anything
Modelling things helps us to understand complex interactions with multiple chaotic elements, where multiple inputs all contribute in a complex way to produce an output.
Want to model how a city would be affected by an infectious disease? Or a warehouse conveyor belt? Simulate an air defence by the military? Or maybe even a yard sale's wealth model?
The fascinating part of modelling is visualising bottlenecks in the environment of something you've modelled.
All of these have been simulated on: https://hash.ai/

Feel free to create your own simulations here, search here or look at the popular ones at the minute here.
Sharing as I saw some fascinating stuff on here, and wanted to let others know if they haven't seen it.
