You don’t even have to watch the whole movie to get the best line from Doctor Strange. Let me set this up (mostly spoiler free). Stephen Strange (Doctor Strange) ends up meeting with The Ancient One and she shows him some seriously awesome stuff. Here is the conversation they have.
Strange: How do I get from here to there?
The Ancient One: How did you become a doctor?
Strange: Study and practice—many years of it.
Oh, you thought this post was going to be about the physics of magic in the Marvel Universe? Wrong. It’s about learning magic in the Marvel Universe. It appears that learning super hero magic is just like learning anything in real life—there are no short cuts.
