Another Earth

"Richard Berendzen: Within our lifetimes, we've marveled as biologists have managed to look at ever smaller and smaller things. And astronomers have looked further and further into the dark night sky, back in time and out in space. But maybe the most mysterious of all is neither the small nor the large: it's us, up close. Could we even recognize ourselves, and if we did, would we know ourselves? What would we say to ourselves? What would we learn from ourselves? What would we really like to see if we could stand outside ourselves and look at us?"
