Differential Systems

Systems described by differential equations—equations that relate rates of change to current states. Differential Systems are the mathematics of continuous change, of processes that unfold smoothly over time. They're used to model everything from planetary motion to population dynamics to chemical reactions. Differential Systems assume continuity, smoothness, predictability—assumptions that hold in some domains but fail in others. They're the tools of classical physics, of engineering, of any domain where change is gradual and causes are proportional. Understanding Differential Systems is understanding a certain kind of world: smooth, predictable, governable.
Example: "His model used differential equations to predict population growth. It worked beautifully—until the population hit a threshold and crashed. Differential Systems assumed smooth change; reality had a discontinuity. The model was perfect and useless. He needed tools that could handle jumps, not just smooth curves."

lead differential

The awkward situation faced by many dog walkers crossing paths when one is on a lead, the other isnt (although many variants are possible with more than one dog per owner.)

The dog owner who has not put their dog on a lead is worried that the owner who has put their dog on a lead is cosidering them to not be in adequate control of their animal.

Likewise the owner who has their dog on a lead may feel they are not giving the dog enough freedom.

Normally resolves itself in one of 3 ways.

1. The non leaded dog owner says 'He's friendly' and the comment is confirmed by the dogs behaviour.

2. The non leaded dog annoys the leaded dog, the leaded dog owner expressed disapproval and apologies are made usually ('Hes normally SOOOOOO friendly!')

3. The owner of the non leaded dog puts their dog on a lead.
-To dog, as if it can understand, while putting lead on it.-

'Sorry mate. Lead differential!'
