Heisenberg's uncertainty principle only seems to have implications for our understanding of the body of knowledge produced by science, not reality itself. The uncertainty comes from the inability to make two separate measurements, since each measurement will disturb the system and change the remaining attribute. This implies that objective reality is still deterministic, albeit unpredictable to us since we can't measure it accurately enough. In other words, the map (science, our measurements) is not the territory (reality). It is an approximation, a very accurate one at that, but still not identical to the real thing. In concrete terms, this means little, since while the system may be deterministic, it's random from our perspective. Nonetheless, it does have profound philosophical implications since if quantum mechanics (in the objective, not scientific sense) are deterministic, and so is every other level leading up the scales, then free will must be an illusion. In fact, I think that the concept of free will is the elephant in the room when in the presence of scientists. Even http://www.youtube.com/watch?v=aJP-1fNSd38" hints that the evidence points to no but doesn't want to say it outright. So what do you all think? I just noticed that there is a similar thread on this subject but I feel that this is addressing a different point.
