Re: re helium cars loaded weights


During my very brief stint as a Teacher, I liked to pose that same
question. You would be surprised to learn ( or maybe not) that adults were
equally likely to think the loaded cars were lighter, as were the students.
My guess is that physics is not an intuitive thought subject, even though we
have had 100 years of public education. I am heartened, though, that most
Americans know who Eminnem is. Andy Carlson.
