Episode notes
Illustration of Social Distance
- Kyle imagines sending a message to Kim Jong-un through a chain of acquaintances.
- This illustrates the concept that we are all connected by surprisingly few social links.
Erdos-Renyi Model Limitations
- The Erdos-Renyi model treats connections as random coin flips between nodes.
- While mathematically tractable, it misses crucial real-world network properties like clustering.
Watts-Strogatz Bridges Network Extremes
- The Watts-Strogatz model begins with clustered networks and introduces few random long-range links.
- This reduces path length dramatically while preserving clustering, mimicking small world traits.
