    Interpretation of the uncertainty principle

    What are \Delta x and \Delta p_x exactly? They are not deviations from the "true values" of x and p_x (like classical uncertainties) since position and momentum are in general not well-defined...? Let's say we have a stream of electrons accelerated from rest through a constant potential and...

    Interpretation of the uncertainty principle

    I have a fundamental question regarding the uncertainty principle (position and momentum). This principle states that it is impossible simultaneously to know both position and momentum with arbitrarily good precision - even in principle. Now, what does "know" mean? No one can prevent you from...
