Heisenberg said that the wave function collapses when the result of a measurement is registered in the mind of an observer.
Einstein said that if quantum theory is true then the moon is not there when nobody is looking at it.
Von Neumann said that "consciousness, whatever it is, appears to be the only thing in physics that can ultimately cause this collapse or observation."
Max Planck: "I regard consciousness as fundamental. I regard matter as derivative from consciousness."
Freeman Dyson: "At the level of single atoms and electrons, the mind of an observer is involved in the description of events. Our consciousness forces the molecular complexes to make choices between one quantum state and another."
Eugene Winger: "It is not possible to formulate the laws of quantum mechanics in a consistent way without reference to the consciousness."
Pascual Jordon: "Observations not only disturb what is to be measured, they produce it."
Wolfgang Pauli: "We do not assume any longer the detached observer, occurring in the idealizations of this classical type of theory, but an observer who by his indeterminable effects creates a new situation, theoretically described as a new state of the observed system."
Martin Rees: "The universe could only come into existence if someone observed it. It does not matter that the observers turned up several billion years later. The universe exists because we are aware of it."
