I’m tired of the Aristotelian physics slander. Yes, heavier object fall faster than light ones, all else equal, *when immersed in a fluid* which is every environment Aristotle had access to. Do the experiment yourself. Drop a bowling ball and a same-sized ball of foam. There’s a great paper called “Aristotle’s Physics: a Physicist’s Look” that demonstrates how Aristotelian physics is a special case approximation of Newtonian physics in the same way Newtonian physics is a special case approximation of relativity and QM. Aristotle’s physics reigned for so long not because people were unthinkingly dogmatic, but because it was genuinely hard to come up with better models. Aristotle had to model celestial objects separately from terrestrial objects because his terrestrial model is describing *terminal* velocity and breaks down in the zero-friction limit. So he had two incompatible models. Newton unified them. Now we have two incompatible models - QM and GR - and are looking for unification. The more things change…






Reading fiction—if it's serious fiction and not bullshit—is not easier than reading philosophy or nonfiction. People saying fiction is easier don't read the right books.
