Morton, in his discussion of ambiguity (and "spectral attunement") refers to quantum phenomena "where a weird overlap between two physical systems--called superposition--can occur"
"What seems to be static and firm starts to reveal its shifty qualities: the way in which it is smeared into itself, or vibrating and not-vibrating at the same time, or shimmering without being pushed in a mechanical way" (see 90 for a claim that everything moves without mechanical input, and thus is alive)
"Quantum events are notoriously difficult to pin down" they are profoundly ambiguous and apepar to have no causal mechanism 'behind' them" (178)
returns to his discussion of hauntedness--"the thing begins to show us that it is haunted--by itself" [see separate note on "haunting"]
see Drucker's levity, perhaps? Morton also mentions levity in a discussion on time (78); see also Morton on "rocking" (179) or "shimmying" (38)
