Episode notes
Interdependent Network Failures
- Interdependent networks amplify vulnerabilities, causing local failures like the 2003 Italian blackout to cascade.
- This requires analyzing networks not in isolation, but as interconnected systems.
Superconductor Experiment
- Researchers applied interdependent network theory to superconductors, creating a physical lab experiment.
- Two layered superconducting networks exhibited cascading failures when heated, mirroring the Italian blackout.
Types of Links
- The key is to distinguish between connectivity links within a network and dependency links between networks.
- In superconductors, current flows within each network, while heat flows between them, creating dependencies.
