Nomenclature: Prior to Ohta's definition above, A. W. Culp produced an energy conversion table describing the different conversions from one energy to another. Culp's treatment made use of a subscript to indicate which energy form is being talked about. Therefore, instead of writing "energy A", like Ohta above, Culp referred to "J e ", to specify electrical form of energy, where "J" refers to "energy", and the " e " subscript refers to electrical form of energy. Culp's notation anticipated Scienceman's (1997) later maxim that all energy should be specified as form energy with the appropriate subscript.
