Re: “How could they be right now?”There’s a moderately well known joke about college physics instructors. (Moderately well known among people who study college physics, at least.) Seems this one professor kept reusing the same questions on his tests from one year to the next. He was asked, “Aren’t you worried about the students copying the answers from last year?” His reply, “The questions don’t change from one year to the next, But the answers? Ah, the answers are different every year!”
