Detector Quotes

Ionizing smoke detectors unnaturally raise the background radiation levels in the human environment.

The bullshit detector is the biggest enemyof every religion."From: "Gesels van een imaginaire god"('Scourges of an imaginary god')

Money is not as good as power, but power is as good as money.

Power is not pleasure, power is pain.

If, years later, I do use the slit detector to observe which way the electron went, it will mean that many years earlier the electron must have passed through one slit or the other. But if I don't use the "slit detector," then the electron must have passed through both slits. This is, of course, extremely weird. My actions at the beginning of the twenty-first century can change what happened thousands of years ago when the electron began its journey. It seems that just as there are multiple futures, there are also multiple pasts, and my acts of observation in the present can decide what happened in the past. As much as it challenges any hope of ever really knowing the future, quantum physics asks whether I can ever really know the past. It seems that the past is also in a superposition of possibilities that crystallize only once they are observed.
