When you have traffic with no traffic policeman, you have gridlock. An education should provide the traffic as well as a way to guide it. A multiple-choice test lists choices A-B-C-D-E. But there's sometimes another category - "OTHER". Civilization consists, in part of being able to respond, "OTHER". You have to know about the range of choices, available to you; you have to know the limitation of those choices; and you have to be able to reject all, and seek a new solution.

Sorry folks, the link on page 103, showing an animation for the various modes of energy
in a molecule has now gone "dead" .... For a rather extensive discussion of the motion(s) of
molecules check out: https://www.youtube.com/watch?v=hx0tSiCQWDc
Watch the video from 6 minutes to 8 minutes to help visualize what is meant by translational,
vibrational and rotational energy. Recall that these three modes are expressions of the
kinetic energy possessed by molecules. The entire video is pretty good, and we will come
back to it, when we want to visualize issues, such as melting and solidification.
