http://hoaxes.org/comments/papparticle2.htmlThe Meaning of impossible in Natural Language The human spirit requires that we reject the word impossible. Any coach in a locker room pep talk tells his team that it is possible for them to beat any other team today. Our most celebrated inventors make the impossible possible. Delivery of a terminal prognosis to a patient is traumatic, so we frequently present undue optimism and say that survival is possible. But there is a difference between what we might call Impossible (with a capital I) or merely impossible (small I meaning difficult). Wikipedia says it well. “Epistemic impossibility” describes things which absolutely cannot occur within our current formulation of the physical laws. This interpretation of the word “impossible” is what is intended in discussions of the impossibility of perpetual motion in a closed system. For clarity we simply use Impossible with capital I for A, and impossible with small i for B.
