Comment on "Can we measure structures to a precision better than the Planck length?"[arXiv:1205.3636], by Sabine Hossenfelder
arXiv:1206.3067
Abstract
First principles do imply a non-zero minimal distance between events in spacetime, but no positive lower bound to the precision of the measurement of a single coordinate.
LaTeX, 6 pages. A discussion about the meaning of localisation added to the previous version, together with two new references
