ELI5: Explain Like I'm 5

Atlas (topology)

Imagine you're playing a game where you're trying to put a puzzle together, but instead of puzzle pieces, you have shapes that are all different sizes and have different numbers of sides. Some of the shapes fit together nicely, but others are really hard to fit in just the right spot.

In the world of math, this game is kind of like studying something called topology. In topology, you're not just looking at shapes, but how they fit together and how they can change. This helps us really understand things like the different kinds of spaces we might find in the world around us.

One thing we might use in topology is called an "atlas." An atlas is like a map that helps us picture what different spaces look like by breaking them down into smaller, simpler shapes that we can fit together like in our puzzle game.

For example, imagine you're trying to figure out what a globe looks like. We know a globe is a sphere, which is a really tricky shape to work with. But if we break the globe down into smaller pieces, like little flat maps that show different parts of the earth, we can start to get a better picture of what a sphere really looks like.

That's how an atlas works in topology. By breaking down shapes into simpler pieces we can work with, we can start to understand more about the different kinds of spaces we might find in the world around us.
