Universality class
Imagine you have a bunch of toys that look different from each other, like a teddy bear, a car, and a block. They might look different on the outside, but they all follow the same rules when you play with them. For example, they all move in a certain way when you push or pull them.
In the same way, there are different systems in science that might look different on the outside, but they behave in the same way under certain conditions. These systems can be grouped into something called a "universality class."
Think of it like different types of toys that follow the same rules of movement, but the toys might look different on the outside. In some cases, it might be hard to tell which toy belongs to which rule if you just look at how they behave.
In the scientific world, universality classes are useful for understanding how different systems behave in similar ways. It allows scientists to create models and theories that apply to a wide range of systems, even if they look very different.
