Mathematical objects

There is no mathematics in a clock. I have devised new, mathematical clock. Every second, a new clock will be created with the hands in a different position.

There is no mathematics in a gun. When you pull the trigger on my ``mathematical gun'' an object with a bullet hole will appear, together with another copy of the gun where the bullet has been fired. The original object and gun will be unchanged.

Driving a car has nothing to do with mathematics. Turning the steering wheel should create a new car moving in a different direction. The fuel tank of this new car would have slightly less fuel than the previous car. This car will be on a new road which is in a slightly different relative position to the car.

You're wanking on over functional programming semantics, when the initial question was very simple copy vs mutate. The modeled implicit state is not part of any of the discussion except your tangents.
