Human history is blessed with many great thinkers who have enlightened us with their observations and theories about the world. Darwin and Wallace discovered for us our place in geological time, Copernicus our place in the solar system, Einstein our place in the universe. One theme that emerges from what we now know is the smallness of our existence. We really do occupy but a molecule of water in a vast, never ending ocean. But what we do with our time can be brilliant, as great artists and scientists have demonstrated. The video below is moving because it represents our place in the cosmos, taking you away and then back again. You feel the nostalgia as you explore, and the elation upon return. Well done to the American Museum of Natural History.
