Personal note. I think some of us just recall. Some of us form associations. And some of us develop models. I know that to undrestand anything I have to understand almost everything about it – otherwise I can’t create a model. But once I create a model I can answer far more questions than I could if I had understanding by association, or recitation. I know that as a kid in school (and I’ve hears this same self reporting from elite physicists), I always felt I needed more time, and that they tested us too early. This is why. It’s also why I want to change education from atomized disciplines focused on memorization and repetition to ‘the grammars’ which treat all bases of knowleddge as variations on the same theme.
