‘Looking at something changes it.’ They call it the uncertainty principle. I’m sure it sounds screwy but even Einstein says the guy’s onto something. […] Sometimes, the more you look, the less you really know.
Freddy Riedenschneider, The Man Who Wasn’t There (2001)
The uncertainty principle: it proves we can’t ever really know what’s going on. But even though you can’t figure anything out, you will be responsible for it on the mid-term.
Larry Gopnik, A Serious Man (2009)
