I heard a lot of this "Quantum theory defies the human logic, it's totally illogical but it works!" and I'm trying to understand whether this is true or not. I don't mean by logic some mind blowing stuff, like teleportation is possible. I mean the kind of logic that would be difficult or impossible to form an intuition of, for example linguistic contradiction (like something existing and not existing at the same time). I hope I posted this in the right section. Thanks.
