$\frac{\mathrm{d}\hat F}{\mathrm{d}t} = -\frac{i}{\hbar}[\hat F,\hat H] + \frac{\partial \hat F}{\partial t}$ ====== Heisenberg Equation ====== Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party. In this section things should be explained by analogy and with pictures and, if necessary, some formulas. The motto in this section is: //the higher the level of abstraction, the better//. The Heisenberg equation describes the time-evolution of observables in quantum mechanics.
