e. Mathematical and scientific
research
In mathematical and scientific research,multimedia are mainly used for modeling and
simulation. For example, a scientist can lookat a molecular model of a particularsubstance and manipulate it to arrive at anew substance. Representative research canbe found in journals such as the Journal of
Multimedia.
