I agree with your answer to the dimensionless point question that I initially posted. I myself did not know the answer to it. It was very insightful. On the other hand I found your comments at the bottom to be childish. You remind me of a schoolchild. Grow up. State your point. Explain why your right. But don't act like a condescending snot. I know your type. I guarantee you that not is ever achieved through mockery.
