Science loves order, breaking down the world into categories, subcategories, levels and classifications. Every element on earth is neatly placed in numerical order from 1 to 113 on the periodic table based on the number of protons in the nucleus of each one’s atoms. Geologists label layers of earth’s crust based on the time period it was laid down in. Every living thing on earth is assigned a unique taxonomic sequence of names, from kingdom down to species, based on its evolutionary relationship to other organisms.
