Yes I definitely phrased that badly, what I meant was there are an infinite number of results one could get from measuring the particle's energy. I'm working through a whole heap of misunderstanding here and suspect I'm getting rather too caught up on Hilbert space but bear with me:
My...
Ok so I'm currently revising my quantum theory course from this year and I've reached the section on the postulates for measurements in quantum mechanics. The one I'm having trouble with is "The only result of a precise measurement of some observable A is one of the eigenvalues of the...
