By observing the falling bottle, I thought, I would come to understand how things are made and unmade. I tried to follow the endless succession of rotations in my mind. But when I thought I had them all before me, each with its own proper motion and duration, I realized there were gaps. There was no way for me to fill these gaps without imagining new rotations: for example, those of the bottle still standing on the windowsill now tumbling; or those of the bottle just fallen and shattered, its pieces flying in all directions; or those of the pieces already scattered and still rotating.
