Historic buildings love a plaque: WASHINGTON SLEPT HERE, stated with total confidence. Physics, meanwhile, gave us Heisenberg, whose uncertainty principle says you can't perfectly pin down both where something is and where it's going. So the only honest plaque possible is this one — he may have slept here; it's uncertain; measuring the claim too precisely would ruin it. It's my favorite genre of joke: completely accurate, deeply stupid, and impossible to explain at a party without gesturing. The parenthetical does the heavy lifting. In this house, we respect the parenthetical.
