I wish I'd learned it in school properly. The way they taught it
   was: "Look how stupid we were 'til this guy came along" And even
   then I remember thinking, "What's so stupid about it?" I mean
   switching to the new model is great for its purposes and it led
   to fantastic findings about gravity... but still, seems valuable
   to know...." But I never liked elitism in science classes. "We
   were stupid before but now we're smart". That always got me
   annoyed because I KNOW 100 years from now, a lot of what we
   think we know about the world will be refined, many things
   overturned completely, and they'll look at US and go, "Oh what
   idiots they were in 2021"... or whatever year this is tongue
