🌪️ Complexity Science — Intro#

Scope — How large‑scale patterns and behaviors emerge from simple interacting components.

Key concepts#

• Complex system — many interacting parts whose collective behavior cannot be predicted from parts alone.
• Emergence — system‑level properties arising from local interactions.
• Nonlinearity — small changes can produce disproportionately large effects.

Seed Q&A triads#

• Q: What distinguishes a complex system from a complicated one?
  A: A complex system exhibits emergent behavior and feedback; a complicated system may have many parts but behaves predictably when decomposed.

• Q: What is emergence in simple terms?
  A: New patterns or behaviors appear at the system level that are not present in individual components.

• Q: Why are complex systems hard to predict?
  A: Nonlinear interactions and feedback loops amplify small differences, limiting long‑term predictability.

Quick activities#

• Identify an everyday complex system (traffic, ecosystems, markets) and list its interacting components.
