   Nothing that you have the wit to understand?   
   The are a lot of steps between the optical spectrum of a cloud of cesium   
   atoms and the frequency of an oscillator running slowly enough for you   
   to be able to count transitions, but there is no question about the   
   objective reality of every last one of them.

   If you don't know how it's done, you can feel free to make fun of it.   
   It makes you look at bit silly.

   Deep space is a usually a pretty good vacuum, but the gear you need to   
   calibrate isn't much used out there.
