Richard Feynman is a great popularizer of physics. He mastered the mathematics of light and wrote the QED, which is the most accurate and detailed description of the behavior of light, which is accessible to a lay audience. The following links are to a series of videos on You Tube. Similar to Six Easy Pieces, where Feynman brings hard to understand, mathematical and physical facts to a lay audience.
In this last video, Feynman is talking about the limitations of language to “map” reality. This is true of all maps. Maps are by definition, limited. We have a word for space and a word for time, but these maps are limited. When this map begins to wear thin, we make a more useful, larger, map, called space-time. And this is how it is as we delve deeper and deeper into “reality”. Our maps wear thin and we find we need more precise, larger maps. As we try to “map” the atom, our map grows more and more unwieldy.. “and this difficulty, we are in.”
