ELI5: Explain Like I'm 5

WZW model

Have you ever thought about how tiny the things around us really are? I’m talking about things that you can’t see with your own eyes, like atoms and particles. Scientists study these tiny things using something called a “model”. Just like how you might build a model airplane or car to better understand how it works, scientists build models of atoms and particles to better understand how they work too.

One of these models is called the WZW model, named after the scientists who first came up with it. It helps us study something called “quantum mechanics”. That’s just a fancy word for how these tiny particles move and interact with each other. The WZW model helps us understand how particles called “gauge fields” work. These gauge fields are like invisible lines that particles follow, kind of like a pattern on a map that helps you find your way.

But why do scientists want to study all of these tiny things anyway? Well, it turns out that understanding how these particles work helps us understand how the universe works! That’s pretty cool, right? So the WZW model helps scientists piece together the puzzle of how the universe really works, one tiny piece at a time.
