What I mean is like for example, a person having “gravitational pull” or someone making a “quantum leap” makes no sense to anyone who knows about physics. Gravity is extremely weak and quantum leaps are tiny.
Or “David versus Goliath” to describe a huge underdoge makes no sense to anyone who knows about history, because nobody bringing a gun to a sword fight is going to be the underdog but that’s essentially what David did.
I’m looking for more examples like that.
They meant it in a homeostasis kind of way, not matter conservation. If a cell responds to an increase in osmotic pressure with more osmotic pressure it will not be a cell for very long. Ditto for body heat, hormones, cell growth or any number of other things in a multicellular organism. I guess it was just an interesting, birds-eye way of approaching the topic, and most of the other stuff was not as memorable.
