You can’t converse with an expert on felines without knowing the names. There are simply too many parts of the body. You have to name them in order to communicate. There’s a reason for the names. It’s nit like someone sadistically decided to give a name to each part. Go ahead have try having a conversation with someone who knows the names and functions of each muscle where you don’t. Looking up each term is not efficient. I’ll take a cop who knows the streets over one who has to look up on GPS. Cops chasing a suspect have report on their progress so that backup can reach them. What do you think they’ll do? Pause every 20 seconds and look up GPS coordinates? Feynman's critique was born of ignorance. He criticizes people for knowing the parts of the cat. In the lecture they criticize him for drawing the map of the cat. They know this already. Feynman does not. He is not at their level and instead of admitting this he makes an ignorant quip. Virtually all knowledge is an easy internet search these days. This has not diminished the need to know, have memorized, terminology. Let S be an infinite dimensional ring extension of R with R a commutative Noetherian ring with identity. Under what conditions is S flat as an R-module? If someone gives a talk on commutative ring theory and the above is the topic they best not waste everyone’s time by looking up the meaning of each word and writing it on the board. Such a person exposes that they aren’t learned enough in the field to be giving a talk.
