MOOC Professors Claim No Responsibility for How Courses Are Used

Steve Kolowich:

Robert Ghrist, a professor of mathematics and electrical and systems engineering at the University of Pennsylvania, knows that wielding vast networks on behalf of nonuniversity benefactors can be tricky business.
Mr. Ghrist specializes in applied topology, an abstract math field. In practice, topological math can help someone harness huge collections of sensory inputs–like those collected by cellphones, for example–to model large environments and solve problems.
The Department of Defense has enlisted Mr. Ghrist to do research along those lines. The Penn professor knows he has little power over how the Pentagon might use his insights. But he says that no longer bothers him.
