Detail of back cover of Physics: Its Marvels and Mysteries, by Dr. Daniel Q. Posin (pictured), 1961.
Doctor Dan the weatherman explained the natural processes of our atmosphere in far more detail than most listeners realized that they wanted to know.
Dan would entertain by writing over the edge of a chalk board as if his ideas were too big to fit into normal space. I remember him explaining weather fronts and space travel which both became more interesting when they left the normal writing surface.
