using your example only, those are words which mean something geometrically and relationally. they are functions for numerical computation of those relationships. they dont describe physical systems that we're all talking about originally. if you show me some QM math about some experiment I will tell you what it means. why is everyone so confused about this? that's one thing here i cant understand easily. it's amazing. first they say we cant use words at all. then they say theyre hardly explainable with words. my mistake earlier was not simply retorting with the question of what % the things are explainable with words and not. mind blowing.
