My general advice on spaced-repetition learning

Spaced-repetition learning is a core part of how I learn (and, most importantly, remember) almost anything, and has been for about five years now. But spaced repetition can be hard to get into because much of the discussion is domain-specific (either language-learning or medical-school study). Most people want to learn things outside those domains. So,Continue reading “My general advice on spaced-repetition learning”

The 7 Commitments from “A Manifesto for Reality-Based Safety Science”

For reference, I have listed the 7 commitments from A Manifesto for Reality-Based Safety Science below: We will investigate work, rather than accidents, as our core object of interest We will describe current work before we prescribe changes We will investigate and theorise before we start measuring We will directly observe the practices that weContinue reading “The 7 Commitments from “A Manifesto for Reality-Based Safety Science””

Reality-Based System Safety — how could we apply it to a hazard analysis technique?

Since we published A manifesto for Reality-based Safety Science, I’ve been thinking and talking about how (and how much) it applies to safety-critical engineering work (rather than just operational safety). The following is a description of how we might apply it to a hazard analysis technique. I’d like to thank Drew Rae, Richard Hawkins andContinue reading “Reality-Based System Safety — how could we apply it to a hazard analysis technique?”
