📚 Hermitian operators represent physical quantities in quantum mechanics. We first show that their eigenvalues, which give the possible outcomes of the measurement of a physical quantity, are always real numbers. Second, we show that their eigenstates, which tell us about the probability of obtaining a particular outcome for a measurement, form a basis of state space, so they can be used to represent any physical state.
