My question for redditors is: what's a specific topic you can proudly say you dominate? What complex or interesting thing can you say you really understand (*or at least understand as far as it can be understood *)?
It can be the operation of a computer, the economy of a country, politics, sociology, a videogame, music, a theory, etc. I hope this sticks. I'd love to see Reddit's answer.
EDIT: Holy shit a lot of replies. Thanks Reddit, these are really interesting. Thanks particularly to those of you who explained a little bit of detail into your respective topics.
EDIT 2: Awesome. It's a slow process to upvote all replies.
EDIT 3: Holy shit, if this thread turns into a retroactive medium to share specific knowledge of certain topics, I'll consider it a triumph.
