What is self-organisation?

Self-organisation is when things arrange themselves without someone telling them what to do.

Imagine you have a big pile of blocks, and no one tells you how to stack them, but somehow, they end up in neat towers or cool shapes. That's self-organisation! It’s like when you pour water into a glass, the water doesn’t need someone to tell it where to go; it just spreads out on its own.

When things are free to move and interact with each other, they can create order by themselves. Like how birds in a flock all fly together without anyone telling them what to do. Each bird just follows the ones next to it, and poof, you get a beautiful, moving pattern in the sky.

Think about a crowd of people at a concert. No one tells them when to cheer or how to move, but when the music starts, they all start jumping together. That’s self-organisation in action!

It's like magic, but without the need for a wizard, just simple rules and freedom to move!
