You've probably heard by now that a total solar eclipse will move across the contiguous United States on August 21, blotting out the sun for a few brief minutes at each spot along the path as the Earth rotates through the shadow cast by the moon (also known as the "umbra").

But it almost seems cruel that a total eclipse is so rare and also so brief. Surely if you could move at the speed of the eclipse, you could see the whole thing, from coast to coast, rather than just settling for a few brief minutes on the plains of Wyoming or wherever you might manage to find yourself along the path of totality on Monday.
