Physics and more physics

Today, we went to the Open Day at the NPL in Teddington.  The NPL is a big building full of physics.  Some chemistry, but mostly physics.  And it's proper physics.  Lots of it. It's hard to explain just how much fun it is wandering around the NPL.  It reminded me of one of the better BBC science documentaries.  You know the ones.  On BBC2 or BBC4 and presented by a scientist who loves their subject.  It was like one of those, but one that you could walk up to and touch and ask questions about. So much stuff I could talk about, so I'm just going to present my ten favourite things from the day... 1. A very echo-y room The reverb chamber is a small-ish room where things echo.

Nor a Jew.  (Although with my Mother's mother being Jewish, I know some would argue the last point.)  But anyway, I am an atheist.  That means I don't be
