For detection systems that record discrete events, such as particle and nuclear detectors, the dead time is the time after each event during which the system is not able to record another event. An everyday life example of this is what happens when someone takes a photo using a flash - another picture cannot be taken immediately afterward because the flash needs a few seconds to recharge. In addition to lowering the detection efficiency, dead times can have other effects, such as creating possible exploits in quantum cryptography.

“Miss U.S.A. is in the same graveyard that [Amanda Jones] the twelve-year-old is. Where the sixteen-year-old is. All the past selves. There comes a time when you have to bury those selves because you’ve grown into another one.”
