benjaminshr Posted November 14, 2009 Share Posted November 14, 2009 Heisenberg Uncertainty Principle: The physicist Werner Heisenberg developed the Heisenberg Uncertainty Principle, which says that when measuring the physical state of a quantum system there's a fundamental limit to the amount of precision that can be achieved.For example, the more precisely you measure the momentum of a particle the less precise your measurement of its position. Again, in Heisenberg's interpretation this wasn't just a measurement error or technological limitation, but an actual physical limit. Link to comment Share on other sites More sharing options...
ajb Posted November 14, 2009 Share Posted November 14, 2009 This is old news (1920's or so) is part of something more general than this. The uncertainty principle comes down to the fact that in general the operators that represent physical observables do not commute. Any text book on quantum mechanics will discuss this.

Christian Feldm Posted November 16, 2009 Share Posted November 16, 2009 Hello ! The meaning of the Heisenberg Uncertancy princip is , that when you couldn`t measure the presens precisly , its easy to see that you also could male only statistical suggestions about the futere of a physical systhem ,without this systhem the prohabelistic foundation of QM and so QM would break down !

swansont Posted November 16, 2009 Share Posted November 16, 2009 This looks a tad like a spambot, methinks. If the signature becomes a link, they will end up where all of the other spambots do. In an iron coffin, with spikes on the inside I'm closing this. Anyone interested in discussing the HUP may search for an older thread that's on-topic, or open up a new one. If the OP can pass the Turing test, asks nicely, and can justify the signature, I'll reopen. Link to comment Share on other sites More sharing options...
