The sculpture Latent Energy depicts a portion of a hydrocarbon molecule transitioning from its liquid to its solid form. This transition is characterized by the release of energy and an expansion in volume. This is the phase transition that Fred Pirkle used in much of his work. Metaphorically speaking, the sculpture also imagines students developing more structure through education. The ‘phase transition’ that occurs in students as they reach a more solid state is also accompanied by a release of energy as they mature.
The large spheres in Latent Energy correspond to carbon atoms. The small spheres correspond to hydrogen atoms. The two small molecules on the lawn are both methane, the smallest hydrocarbon molecule, each with one carbon atom. The tall structure shows a portion of a longer hydrocarbon molecule moving from a liquid to a solid form. The solid form is characterized by a linear chain of carbon atoms, each of which has two hydrogen atoms attached to it.
The sculpture is located in front of the Fred Pirkle Engineering & Technology Center at Sam Houston State University in Huntsville, TX.
