Hi.

   That was quite a good podcast.  Thanks for making that.   

Most positive:
   The info about the telescope was well researched and has probably doubled what I knew about it. 
    I'm also always impressed that you get involved with all sorts of organisations and take questions from all sorts of places in the world.

Most negative:
    Chris' explanation of why there are two tides every day.

Best Wishes.
