Remember when chemistry was just four elements and you didn't need a PhD to understand what you were made of? Medieval scientists be like: "Hmm yes, this rock has too much Earth energy, better balance it with some Fire." ๐ฅ Modern chemists need 118 elements and counting, while ancient Greeks were vibing with just Earth, Water, Air, and Fire. No wonder they had time to philosophize all day - their periodic table fit on a napkin! Next time someone tries to explain quantum chemistry to you, just point at this and say "I prefer the classical approach, thank you very much."
