Model specification

Imagine you want to build something with your building blocks, but you don't know exactly what you want to build. First, you need to decide what shape or structure you want your building to be. That's like model specification.

In real life, when we want to study something mathematically, we use models. A model is a simplified version of the real world we can study and understand more easily.

But, just like when you're building with blocks, you need to decide what shape or structure you want your model to be. For example, if you're studying how fast cars go, you might choose to build a model that looks like a ramp. That ramp model is your specification.

Once you have your specification, you can start filling in all the details. Adding colors, textures, and other pieces to the building blocks to create your model. In the same way, you need to fill in the details of the model in real life so that you can study it better.

So, model specification is deciding what kind of model you want to make before you add all the details. Just like with building blocks, you need to decide what you're building before you start putting all the pieces together.
