“Instead of wave functions we could talk about this; that if a source of a certain kind emits a particle, and a detector is there to receive it, we can give the amplitude that the source will emit and the detector receive.”
“Repeated studies (such as by the National Academy of Science) has shown that the "lie detector" is no more accurate than dunking "witches" used to be.”
“If your smoke detector is more than ten years old, replace it; same thing for any carbon monoxide detector more than five years old.”
“But I don't doubt that what Sofie said also applies in my case: my bullshit detector is likely better honed towards fantasy than SF, and so it may be that I avoid the more trite examples of the former, but pick up more of the latter.”
“If detectors 1 or 2 do the detecting then the which-path information has been "erased" and the main detector shows a wave-like interference pattern.”
“Generally, there is a main detector for the signal photon to check for interference patterns and three detectors (a fourth detector is implied) to detect an entangled twin photon.”
“Which detector is used to measure the twin photon is left up to quantum chance.”
“* I generally find my detector is quite accurate; however, it has no ability to detect if the good story is well executed.”
