Rattled, I listen to Neil deGrasse Tyson as others might listen to a preacher. Science in the face of the fear that comes with being human is the only thing that calms me. And not just science for its own sake, but the joy in science. The marvel at all we don't know. That we feed on flora and fauna, and then die to feed flora and fauna. That we are, actually, made of stardust, and so is everything, right down to every grain of sand on Hirtle's Beach.
