First appearance of Heisenberg's important paper in which "succeded in sketching invariant procedures for establishing such a theory [n new relativistic invariant theory quantum theory in which the fundamental length laid down the limitations of present quantum theory in the same way as the constants c and h fixed the limitations fo classical physics] by developing a formalism of time displacement in the interaction picture (which later became standard in quantum mechanics)".
