Quantum Physics Experiments

Check out the May/June 2008 issue of SEED magazine. There is an article titled The Reality Tests which has a pretty good, but very brief, overview of quantum theory and mentions Bohm and several others. The kicker is that a group in Vienna has actually experimentally proven that we create the world just by looking at it. While the experiments were not described in detail, they confirmed that photons' "polarizations didn't exist before being measured."

The group then talked about real-world objects and concluded (from some experiments not described at all in the article):

... it does not matter how many particles are around, or how large an object is, quantum mechanics always holds true. The reason we see our world as we do us because of what we use to observe it. The human body is a just barely adequate measuring device. Quantum mechanics does not always wash itself out [i.e. the large number of particles "are in constant interaction and their environment serves to 'decohere' the quantum world -- eliminate superpositions -- to create the classical one we observer"], but to observe its effects for larger and larger objects we would need more and more accurate measurement devices. We just do not have the sensitivity to observe the quantum effects around us. In essence we do create the classical world we perceive ...

Not much detail in the article but very interesting nonetheless.
