A solution to the quantum harmonic oscillator time independent Schrodinger equation by cleverness, factoring the Hamiltonian, introduction of ladder operators, expression of the commutator, basic operator algebra, demonstration of the effect of the ladder operators on a hypothetical stationary state, and the resulting algebraic structure of the solutions.
