The document discusses different types of patterns found in nature, including concentric, radial, spiral, fractal, branching, and network patterns. It provides examples of each type of pattern, such as tree rings, agate formations, hurricane spirals, coastlines, leaves, and river networks. The document also discusses how these patterns arise from natural processes and how they can be applied in human designs.

Editor's Notes
- 1. Intro 2. Questions: a. Limited time. If we have time I’ll answer them after the discussion. 3. Why Patterns? a. Better designs b. Understand phenomena c. Patterns, pattern language i. repeating themes throughout design, by humans, or in nature
- Zones Urban planning - “the urban core”
- Tree rings dendrochronology
- Like tree rings, different medium
- All scales
- Sectors Many plants in dry ecosystems develops forms to concentrate water near their roots Bus Rapid Transit arterial systems
- Galaxies Sunflowers Turbulence
- No matter how large, the shape remains the same Accreting shell on the outer lip to grow
- Tenacity Flexiblity/Spring
- Some trees grow in a helical form Classic Example - DNA - compact information storage
- Algae growth off Agentina Ocean currents, Mixing of Two Concentrations
- Mushroom forms
- Mixing / Entropy
- Compare with human intestines
- Streamline forms from fluids
- in lichens, at reef edges A very small notch or indentation
- 2x more edge. More food. More fish.
- Hired by the British govt to measure the coastline of Britian. Surface Area At each level of detail, the length got larger, approaching infinity. 1. Pro - more interface for the amount of area, like intestines a. Humid/Temperate Climates - Trees with 10-30 acres of edge. b. Con - more edge = more material, material conserving designs (like geodesic, bubbles) Arid Climates - Barrel Cactus, round like a geodesic dome, little edge, low water loss. In desert climates: make deep pond with low surface area.
- Edge or Surface Area “Boundaries”, Interfaces betweeen various conditions Most fertile areas are edges (conceptually, and in the environmental, intertidal zones)
- Pressure = winds Elevation = erosion, water speed The sweet spot. Walls. Soft or Sharp Adding slower transitions for varied species
- Branches never reconnect Evolutionary decent? Gene swapping. Microbial life?
- Neurons - “dendrites” - dentrites link together to form network Branches - high average cost from point to point Slow communication: bureaucracy
- Common form in nature Why? What are the reasons? Flow could be in reverse.
- Orders - each size Rivlet, Creek, Stream, River, Estuary…
- Water - the path of least resistance Doesn’t store water Flows both ways: Water Sediment Downstream / Salmon Nutrients Upstream Nitrogen
- Note the stream lines. Low gradients?
- Contraction Expansive clay social networks mycelium
- Are we recognizing patterns yet? The US at night. Long exposure.
- The Internet. Which is Resiliant? Scale-free/Small world = few hops to any node in the network Scale-free can scale without a loss in quality Explain bell and power law curves. Hubs and Keystone species
