First sentence: Heisenberg's observation that the products of the quantum-theoretical analogues of the classical Fourier series, which were supposed to describe the dynamical variables of atomic systems, did not necessarily commute, led to an obvious conclusion: the calculus used in classical mechanics would not serve as an appropriate tool in atomic theory, and different mathematical methods had to be applied.
