Oh dear – I stumbled upon https://en.wikipedia.org/wiki/Analogy – one of my favorite topics. I never actually read the Wikipedia page on analogy even though I love analogy and metaphor.
Considering that many physical systems are nearly perfect (but not quite) analogues of each other, if you learn one, you’ve learned the ‘gist’ of all of them…. and the same is true for analogies in general. Good analogies can unlock doors (there’s an analogy/metaphor) to MANY different ideas.
Oh dear… I gotta be careful or I’ll be clicking off from that page and coming back to it all day long if I could smile emoticon
