Emergent behaviour (murmuration) in a bird-flock — Illustrative art created by the author

Picture this: You are at a park, enjoying a lovely sunny day. A huge flock of hundred or so birds swoops overhead, moving gracefully in unison. The birds change direction together, never crashing into one another, like a well-choreographed dance troupe. “How do they do that?” you wonder, as you watch the mesmerising spectacle unfold.

This subtle phenomenon has profound consequences, and may even form the basis of what we call intelligence and conscience.

I this essay, I will be diving into the rabbit hole of complex (adaptive) systems and present how even the simplest components can act in unison to create the most extraordinary…
