This review puts into perspective the present state and prospects for contr
olling phenomena in atoms and molecules. The topics considered include the
nature of physical and chemical control objectives, the development of poss
ible ii quantum control rules of thumb, the theoretical design of controls
and their Laboratory tory realization, quantum learning and feedback contro
l in the laboratory, bulk media influences, and the ability to utilize cohe
rent quantum manipulation as a means for extracting microscopic information
. The preview of the field presented here suggests that important advances
in the control of molecules and the capability of Learning about molecular
interactions may be reached through the application of emerging theoretical
concepts and laboratory technologies.
