In conversation with the ghosts and the spaces these ghosts inhabit, At the Edge of the Dirac Sea interweaves personal and ancestral narrative to consider the spiritual crises provoked by the trauma of the Holocaust and its lingering intergenerational reverberations. In its reaching for the metaphors of physics, architecture, and psyche, this work aims to speak the unlanguagable experience, whether of grief or of grace, in whatever language can be found.
