Yoneda product

So, a Yoneda product is a big fancy math term that basically means we can take things and put them together in new ways to learn more about them.

Imagine you have a bunch of different shapes like circles, squares, and triangles. The Yoneda product lets us take two shapes and put them together to make a new shape. For example, if we take a circle and a triangle, we might end up with a cone shape!

Now, in math, we don't really work with shapes like circles and triangles. We work with things called categories. But the Yoneda product works the same way! We can take two categories and put them together to make a new one. And just like with the shapes, this can help us learn more about the individual categories.

So basically, the Yoneda product lets us take two categories and combine them in a cool way that helps us learn more about each of them. It's like mixing two colors together to make a new one!
