In the field of Chaos Theory, there’s a concept called the Synchronization of Chaos—disparate systems filled with randomness will influence the disorder in other systems when coupled together. From a theoretical perspective, these influences can be surprising. It’s difficult to understand exactly how a butterfly flapping its wings could lead to a devastating tornado. But we often see the influences of seemingly unconnected systems play out in real life.
