fixed points, stability, bifurcations (saddle-node, transcritical, pitchfork)

## Why it matters

Studies systems evolving in time, from stable equilibria to chaos; connects ODE theory, nonlinear physics and applied math.

## Where it is used

Population dynamics, planetary motion, weather and climate, financial cycles, neural dynamics, stabilization of machines.

## How you know you have learned it

Produce working code/model + convergence/validation/error analysis.

## What you need first
