Okay kiddo, let's talk about something called coherent isomorphism.
Imagine you have two things that look different, like two different toys. But even though they look different, they actually work in a very similar way. Maybe they both spin, or they both have buttons you can press.
Now let's say you can take one of these toys apart and see all the different parts that make it work. You can do the same thing with the other toy too, but it might have different parts or be put together in a different way.
But here's the cool part: even though the toys look different and have different parts, you can still see how they work in a similar way. It's like they have a "coherent isomorphism" where you can compare them and see how they're connected.
In science, we use the word "isomorphism" to describe when two things have the same structure, even if they look different on the surface. And when we say "coherent" isomorphism, we mean that the connection between the two things is very clear and easy to understand.
So, coherent isomorphism is like seeing how two things that look different actually have the same underlying structure, and you can understand how they work by comparing them. Pretty cool, right?
