I hit the tag limit earlier, but let's spend a few minutes thinking about twenty-something Hermann tutoring adolescent Mako and Chuck.
And he makes sure the very first concept he teaches them is general relativity, so they don't spend any longer than necessary working with outdated and inaccurate information (and also if they're not astrophysicist material, he'll know up front). The scientific ramifications, the historical ramifications; what the hell, Hermann sits them down to watch Einstein and Eddington--it's watered down, but it gets the message across about Why This Was Important and it's good for an ESL student, and Hermann admires Eddington's reverence, his drive to do what's right despite the potential disapproval of the scientific community. (Also, it's like, Vanessa's favorite movie. Lady loves Andy Serkis.)
And Mako is still learning English, so it takes her a bit longer, but Chuck Hansen at 13, 14, is totally comfortable with it, right out of the gate. Doesn't even protest, "But they told me--" Just dives right in. And after a little while, Mako's vocabulary catches up and it turns out she has no problem with the material either, and this thing that overturned Hermann's entire world when he was not much older than them is no big deal for two kids who have had their foundations so thoroughly shaken. They're completely unfazed by a scientific revelation that invalidates most of what they've been taught in the past.
