I like this topic. I've described "understanding" (click) as a form of pattern-matching before. It's also why I avoid "word arguments", where people endlessly debate definitions instead of going for the substance of the discussion (the crystals), and why I avoid technical words with heavily loaded definitions (big, complex crystals with tiny labels). It can also help explain why some people just won't get it... their brain might not have the processing power to fully contain a crystal (pattern) all at one time, or they might not be able to encode all of it into memory, so it ends up warped.
