26Sometimes, authors do not draw obvious conclusions from their own findings in order to avoid touching the IUP-monumentum. I mention as an example a paper by Holze and Scott [67]. These authors find in their careful theoretical study of non-relativistic particle-particle collisions a definite violation of the IUP. One would expect that this result leads to the conclusion that the IUP is not valid. However this conclusion is not drawn by Holze and Scott. They note instead that ”This calculation suggests that the gamma-ray microscope example of Bohr and Heisenberg was not appropriate for illustrating the uncertainty principle” (p. 489 of [67])
