The liminal space is the threshold--the moment of becoming, the moment of intersection, the moment of occupying two spaces at the same time. It is the moment when the writer's pen hits the page and the imagination becomes real; it is the moment when inertia and motion are one; it is the moment when the past transitions into the future. Students, artists, scientists, scholars, writers, musicians, and athletes were invited to explore the liminal spaces in their own disciplines and in their own lives and they took part in TEDxPineCrestSchool's LIMINALSPACES.
