Mom, is there a speed bump in our car? One day,my baby asked me,"Mom, is there a speed bump in our car?" "No, there isn't. The speed bump is set up on the road."I answered. He nodded .But after a second, he asked again,"Mom, is there a speed bump in our car?" I answered again,"No, there isn't.it's set up the road..." Then,after a second again. Once again,he asked me,"Mom, is there ...?" Oh!!!Quickly! I took out the pen and the paper.Drawing the planform first. Then drawing the side elevation. Trying to explain from all angles where the speed bump is.
