Applied category theory

Applied category theory is a type of math that helps people understand how things are related to each other. It's like a big puzzle where you try to put different things together to see how they fit.

For example, let's say you wanted to understand how a baby's brain works. A category theorist might draw pictures of different parts of the brain and show how they are connected to each other. This would help them see how the brain is organized and how it works to help the baby learn and grow.

Another example is in computer programming. Category theory can help programmers understand how different pieces of code work together to create a program. By thinking about the code in terms of categories, they can find ways to make the program run more efficiently and be easier to understand.

Overall, applied category theory helps people understand complex systems by organizing them into categories and showing how they are related to each other. By doing this, we can solve problems and create new and better ways of doing things.
