Historians often label epochs of human history according to their material technologies—the bronze age, the iron age, and, most recently, the silicon age.
Materials scientists are the closest thing we have to deities. They wield the power of the divine, and make our world as economists, sociologists, artists, politicians, etc., vie for credit.
