If it helps any I keep forgetting what an abelian group is. I also never grok'd eigen values or vectors. So go ahead and name drop a few terms from set theory.
But really lingo has nothing to do with intelligence, but it is the map of the territory for any discussion. The first and hardest step in getting into any new field is just learning the vocabulary. After that you can specialize as a BSer like me who talks a big game or an expert like ChipTuner who actually knows what the words mean and gets things done.
