Input (English): The Lorentzian profile due to the natural broadening of spectral lines is due to this statement. Mandelshtam and Tamm used a general observable operator to reformulate an alternative to this statement and other forms of it detail the relation between the phase of the Ginzberg-Landau parameter and the number of electrons in a superconductor. This statement can be viewed as a special case of the Robertson-Schrodinger inequality, and the canonical commutation relation of quantum mechanics can be used to arrive at this relation in its most familiar form. This statement from quantum mechanics comes in energy-time and position-momentum varieties. For 10 points, what statement, named for a German physicist, says that no two non-commuting observables can be simultaneously measured to infinitely high precision
