Science Friday
      
      Here is synergy for you.  This Friday I'll be a guest on NPR's 
Science Friday, in the second hour (3:00-4:00 Eastern time).  One of the things we'll be talking about is dark energy, including some new data bearing on whether the universe will be torn apart in a 
Big Rip.  (The Big Rip is a little overhyped, actually; hopefully I'll say more about that later.)
But one of the reasons I was invited was that the producer, Annette Heist, noticed that I had a blog, and in particular that I had mentioned 
NPR.  And now I can tell you about it using the blog.  Dizzying.
