Einstein's equivalence principle, which states the local equivalence between gravity and acceleration with respect to a frame of reference, requires that a free falling observer result in a co-moving local Minkowski space as a spaceship under only the influence of gravity. However, a "free fall" in a Lorentz manifold may not uniquely result in a local Minkowski space, and a Lorentz manifold wit...

In this article we critically examine the principle of equivalence of care in prison medicine. First, we provide an overview of how the principle of equivalence is utilized in various national and international guidelines on health care provision to prisoners. Second, we outline some of the problems associated with its applications, and argue that the principle of equivalence should go beyond e...
