Chemistry is an old science. It goes back before history, with the control of fire, preparing and preserving food, and medicinal and mining operations. Thus it has a rich legacy with vestigial archaic terminology.
Chemistry is a new science.
Although millions of man-made compounds have been manufactured by armies of researchers, chemistry is still developing a molecular engineering that can produce materials with desired properties on demand. Chemistry is a physical science. Therefore it draws on the heritage of mathematics and physics for models and concepts. Chemistry is a broad science. Although some principles have been discovered which apply to chemical phenomena ranging from stars to microbes, there is still much art in the science of chemistry.
