Some of America’s most beautiful spaces, our college and university campuses, are closed and empty these days. Schools have canceled their spring semesters and commencements because of the COVID-19 virus; classrooms, dormitories, and athletic facilities have been closed.

Students at many institutions are told that they can continue to access instruction online. But exams and grades have been canceled in many cases, and one suspects that online viewership will be sporadic and concentration intermittent.
