What is an isomorphism?
An isomorphism is a one-to-one mapping from two sets, and encoding your domain model involves finding a mapping between the real world and your code. So does domain modeling involve isomorphism?

Applying domain modeling to an existing data structure
Domain modeling also works after you've already got lots of code. How can we apply domain modeling analysis to existing data structures?

What is the closure property?
I discuss the closure property, which creates operations that can be nested. It's one thing that makes an API feel like a DSL.

All about level three, algebraic modeling
What do I mean by algebra? And how do we get from level 0 to level 3?

Why do we need to model time?
All sophisticated models need to include time. We discuss two main ways to do that.
