Okay kiddo, so let's say you have a map of a city that you want to make into a different shape. It's like when you play with Play-Doh and you squish it into a new shape. But this time, we want to keep all the streets and buildings in the map the same, we just want to make the whole thing look different.
Well, there's a way to do that, and it's called the Schwarz-Christoffel mapping. It's kind of like a magic trick that mathematicians use. They take the map and they use a bunch of crazy formulas to turn it into a new shape.
The way they do this is by using something called a complex plane. It's like a big piece of graph paper, but instead of just having an x and y coordinate, it has two parts called a real part and an imaginary part. It's kind of like having a map that's in two dimensions instead of just one.
Then they use some more math to figure out how to stretch and shrink the map so that it fits inside the complex plane. This is kind of like when you put a piece of paper on top of a smaller piece of paper and trace around it, making it bigger or smaller.
Once the map is in the complex plane, they use even more math to transform it into the new shape they want. This is like when you take the Play-Doh and mold it into a new shape.
So that's it, kiddo! It's a way to turn maps into different shapes using lots of math and a complex plane.
