Symmetry, Duality, and Cinema
— Title of a Paris conference held June 17, 2010
From that conference, Edward Frenkel on symmetry and duality—
"Symmetry plays an important role in geometry, number theory, and quantum physics. I will discuss the links between these areas from the vantage point of the Langlands Program. In this context 'duality' means that the same theory, or category, may be described in two radically different ways. This leads to many surprising consequences."

This journal on the date of the Paris conference
had a post, "Nighttown," with some remarks about
the duality of darkness and light. Its conclusion—
"By groping toward the light we are made to realize
how deep the darkness is around us."
