Davis is made up of many things. As humans do, we often categorize them into basic units and try to trace their structures. From social structures to timelines, we put things into place by their street addresses, and otherwise try to find fundamental units. One of these categorical units is an element. No, not air, water, fire and earth. We're talking the chemical elements. Many are found in Davis, and — using this somewhat localized chart — you can find Davis in them.
