A fundamental pattern in nature and human design where systems exist as hierarchical arrangements of subsystems contained within larger systems, each level exhibiting unique properties while remaining interconnected with the whole.

Nested Systems

Nested systems represent a universal organizational principle found throughout nature, technology, and human society, where complex structures are composed of multiple layers of interconnected subsystems. This pattern of emergence creates robust and adaptable arrangements that can be observed from the microscopic to the cosmic scale.

Core Characteristics

Hierarchical Organization
- Multiple levels of containment
- Clear boundaries between layers
- Scalability across different magnitudes
- Modularity in component arrangement
Information Flow
- Vertical communication between levels
- Horizontal communication within levels
- Feedback Loops connecting different scales
- Information Theory principles governing exchanges

Natural Examples

Biological Systems

Cells within tissues within organs within organisms
Ecosystems containing multiple nested food webs
Neural networks structured in hierarchical patterns

Physical Systems

Atomic structures within molecules within materials
Fractals in natural formations
Planetary systems within galaxies within clusters
