Mixed Hodge structure

Mixed Hodge Structure is a very complicated idea that people use to study shapes and spaces. Imagine you have a big box full of Legos that you want to build into a castle. Some Legos are red, some are blue, and some are green. Some Legos are flat like squares and some are pointy like triangles. Mixed Hodge Structure is like thinking about how all the different types of Legos fit together to make the castle. It's like looking at the shapes and colors in a special way to understand how they all work together to create something bigger. Scientists use Mixed Hodge Structure to study shapes and spaces in the same way you might use Legos to build a castle.
