Term: quantum chromodynamics: a theory of strong interactions between elementary particles (including the interaction that binds protons and neutrons in the nucleus); it assumes that strongly interacting particles (hadrons) are made of quarks and that gluons bind the quarks together
Broader: quantum field theory: the branch of quantum physics that is concerned with the theory of fields; it was motivated by the question of how an atom radiates light as its electrons jump from excited states | Unrelated: clean room: a room that is virtually free of dust or bacteria; used in laboratory work and in assembly or repair of precision equipment
