WebResidents may complete a 1-2 month international rotation after their intern year of residency. All international electives must be approved by the residency program … WebApr 23, 2024 · Essentially you'd be asking about “nice” paths in the parameter space of all transformations. But characterizing what is a nice path might be more difficult than it looks at first glance. While your example with rotation only looks easy enough, it might be difficult to distinguish rotational and other effects. Take e.g. a 180° rotation.
