Re: Quantum measurements and consciousness

A photon is a particle that ITSELF is a result of the collapse of the

are themselves properties of the ONE collapse. There are no isolated
events. All particles are entangled. There is no: A causes B to
collapse, and B causes A to collapse.

Anders. what do you think of the Afshar experiment which tries
to show the whole wavefunction thing is a misunderstanding. It
disprove the principle of complementary. All experiments
(like the concept you mentioned) showed that wave and particle
can't exist at the same time. But in Afshar, it seems they
can. If true. This means the wave function doesn't collapse
to give a particle property because they can exist at the
same time.

To understand QM at its core better. We must thoroughly
analyze Afshar stuff. He has an interesting one and half
hour video at (with full charts and demo):

go to left screen and choose PIQudos, then a screen will pop
up. Go to the bottom and open "View: Measurement without
"measurement": Experimental violation of Complementarity
and its aftermath.

What do you make of Afshar? I can't quite put a finger on it why
he is right if he is right or why he is wrong if he is wrong.
