Learn.Forget. Remember. Science of learning and forgetting.
In ordinary human discourse, the word ”forget” has multiple shades of meaning. It can refer to the irreversible elimination of a certain knowledge item from memory; or it can mean something milder, as in cases where someone ”forgets” something, but then remembers it shortly after. In the latter case, ”forgetting” means that the knowledge item has been stored in some portion of memory from which access is slow and uncertain.
