    "abstract": "Position and momentum of a particle can take any value in a continuous\nspectrum; these values are independent but their indeterminacies are\ncorrelated; momentum and position are mutually the generators of the\ntransformations in each other. It is shown in a concise way, how all these\nfeatures arise solely from their commutation relation $[X,P]=i\\hbar$. The\narticle is complete and self contained, adequate for didactic use.",
