Alumnus, scientist finds new life passion in retirement as novelist

Long after his retirement as a scientist, Paul Mark Tag would continue thinking about the concept of weather modification. The notion that humans could influence weather, either accidentally or on purpose, was the focus of part of his career with the U.S. Naval Research Laboratory, and it would also form the basis for his first novel, penned in retirement. He was first exposed to this idea during his days as a Penn State student in the 1960s and 1970s.
