"It's called the Schrödinger Night Fever principle."
"I don't understand."
"It's simple. If you go to see Saturday Night Fever expecting it to be good, it's a corker. However, if you go expecting it to be a crock of shit, it's that too. Thu Saturday Night Fever can exist in two mutually opposing states at the very same time, yet only by the weight of our expectations. From this principle we can deduce that any opposing states can be governed by human expectation - even, as in the case of retro.deficit engineering, the present use of a future technology."
"I think I understand that," said Landen. "Does it work with any John Travolta movie?"
