I've had a fairly stable style over the years where whenever I try to explain something, I can always understand my own explanation again, many years later.
Does this happen to everyone? When you read expository writing, recipes, code, analyses that you wrote many years ago, do you feel like the signposts you left behind back then help you perfectly understand your own self?
Currently prompted by this stupid thing on #NonstandardAnalysis I wrote in undergrad:
It goes a bit further than this in that I imprint on every explanation. Once I find an explanation that makes sense, I have to go back to that explanation again and again to understand again the same idea. Alternate explanations don't really take hold unless I can compare them with the first one I understood.
Maybe I should be saying #proof instead of explanation, since I'm mostly but not only thinking of #mathematics.
Maybe it's because I think, wait, I've seen this before, how did it go? I know I've figured this out before. And then I can't let go until I retrace my steps, even if potentially new steps might work better.
