Gibson's book on affordances: The Ecological Approach to Visual PerceptionAlexander's 15 Properties are explained in The Nature of Order Book One.Part 3: 23:47
What it "is" versus what it "does", three levels of software: the backend, the interaction layer, the layer of life. Music software example. Basecamp concept example. -

Risk, thin-tailed vs. fat-tailed variables, how underlying structure gives rise to different shapes of distributions, orthogonality and interdependenceMentioned:
Nassim Taleb. See Probability, Risk, and Extremes (PDF) on thin vs fat-tailed variables. Re: the relationship between distributions and underlying structure: "... we cannot rule out that it is not fat tailed unless we understand the process." (emphasis added)Part 4: 30:14
