Chemistry
In its most basic sense, chemistry is the science of taking things apart and putting things together - at the atomic and molecular levels. But this rather short definition encompasses a huge field of
study. Chemists explore the structure and properties of the atoms and molecules that make up our physical world. They also study the reactions that produce compounds and think up new and useful ways of producing such compounds. Whether creating stronger fibers or more effective medicines, they help to bring useful, new things into existence.
