Pay attention, there will be a quiz at the end. No but seriously though: check out this educational video by outsidexbox, which looks at quantum mechanics, and how it relates to BioShock Infinite. Or in other words, the science behind stuff in BioShock Infinite (like floating cities, or multiple universes), along with a look at the real-life important figures that made the discoveries.

Not that the game presents wholly accurate science, of course—but that doesn't mean the ideas don't come from somewhere, or that they don't resemble actual real-world ideas!
