'Reflecting on Hiroshima, 6 August 1945, Karen Barad writes :
'Time stopped. The internal mechanisms melted...Time died in a flash. Its demise captured in shadows: silhouettes of people, animals, plants, and objects, its last moment of existence emblazoned on walls. Never before was it possible to kill time, not like this. Atomic clocks. Doomsday clocks. The hands of time indeterminately positioned as creeping toward the midnight of human and more-than-human existence, moving, and no longer moving.' (Introduction)
