The Cauchy-Schwartz inequality is used to derive this statement, which relates the standard deviation of two conjugate variables to Planck's constant over 4 pi.
One statement of it is applicable to the measurement of a quantum state of a particle, and has an energy-time formulation. The Bohr model violates this statement since it assigns a definite radius to the electron. The Cauchy-Schwartz inequality is used to derive this statement, which relates the standard deviation of two conjugate variables to Planck's constant over 4 pi. For 10 points, identify this statement which implies that one cannot simultaneously know both the position and velocity of a particle, named for a German physicist.
