    Study Notes

    • The uncertainty principle states that it is in general not possible to predict the value of a quantity with arbitrary certainty, even if all initial conditions are specified.

    • The uncertainty principle is a fundamental result of quantum mechanics, and is observed routinely in experiments.

    • The uncertainty principle arises from the matter wave nature of all quantum objects.

    • The uncertainty principle has its roots in how we apply calculus to write the basic equations of mechanics.

    • The uncertainty principle is important because it allows for the determination of the limits of our knowledge about physical systems.

    • The wave function describes the position and momentum of a particle, which is extremely uncertain.

    • Adding together many plane waves of different momenta results in a less precise position and momentum.

    • The precision of position and momentum can be quantified by the standard deviation.

    • The Robertson–Schrödinger uncertainty relation states that the uncertainty in the position and momentum of a particle is equal.

    • The uncertainty relation can be generalized to describe mixed states.

    • The Robertson–Schrödinger uncertainty relation can be improved by noting that it must hold for all components in any decomposition of the density matrix.
