I don't come to Medium for answers to big questions (although some of those are here); I come more for interesting questions that I can 'dig in' on a bit, then the responses are a perfect place to put what I figured out.

I try to use the 'Feinman technique' (if you can't explain it to 12 year olds, you don't actually understand it) but I target SciAm readership level, which seems a safe assumption here. I learned that technique decades before I had any idea who Richard Feinman was - back when I was in college (want to know something? teach it to someone). If I get something wrong, I have a decent chance of someone telling me

Medium feels a lot like being an undergrad, minus the beer parties followed by early classes the next day. :-)
