Heisenberg's uncertainity princple

  1. Oct 10, 2012 #1
    i'm been searching the internet for resources regarding heisenberg's uncertainity princple for my year 12 assignment, however, have can't find any clear sources. Would someone please suggest a comprehensive sources thank you

    What kind of resources do you require? I'm guessing you aren't wanting a derivation from principles of quantum mechanics, but perhaps a more cultural overview?

    If that's the case then Quantum, by Manjit Kumar is a good book. Otherwise, have a look on wikipedia under Uncerternty Principle and see what it is you're interested in and follow the references there.

    Many sources listed here:

    [This has a good discussion followed by a lot of references.]


    Albert Messiah, Quantum Mechanics, p119
    “When carrying out a measurement of position or momentum on an individual system represented by psi, no definite prediction can be made about the result. The predictions defined here apply to a very large number [N] of equivalent systems independent of each other each system being represented by the same wave function [psi]. If one carries out a position measurement on each one of them, The probability density P[r], or momentum density, gives the distribution of the [N] results of measurements in the limit where the number N of members of this statistical ensemble approaches infinity.”

    A new ensemble interpretation of quantum mechanics is proposed according to which the ensemble associated to a quantum state really exists: it is the ensemble of all the systems in the same quantum state in the universe…The problem is that Smolin’s real ensemble is non-local.


    ZapperZ explains this in his blog Misconception of the Heisenberg Uncertainty Principle.


    the eigenstates corresponding to the respective measurement operators are incompatible. As a result, the system cannot simultaneously have both a definite value of qj and a definite value of pj. See Fourier Transforms and Uncertainty for more on this topic.

    I'd also suggest you search these forums for discussions where you will find careful dissection about what HUPis and what it is NOT...

    Part of the lecture series by Feynmann on QED delves into the heisenberg principle. They have been turned into an accessible set of books by an author, but they are essentially transcripts.

    I used them during my A-levels and found it useful

    any more specific sources which explain Heisenberg uncertainty principle in a more simple manner? (as in grade 12 standard)
