[QUOTE="DaveC426913, post: 6841806, member: 15808"] In case it's not intuitive that it's due to the nature of the system and not a measurement problem, nature has been kind enough to provide a real-world demonstration in the form of [B]Bose-Einstein Condensates[/B]. Take a bunch of atoms - normally very discrete objects - and cool them down arbitrarily close to absolute zero. Effectively, all motion stops, meaning their momentum approaches arbitrarily close to zero. Do you now know the exact position [U]and[/U] momentum of these erstwhile discrete objects? Nope. Their normally discrete nature starts to smear out into a hazy cloud, until the concept of "position" no longer applies. The more you restrict their momentum, the bigger the smear gets. [/QUOTE]
