Interesting, thanks for the pointer. And it closes the circle...

The first slide is a quote from one of Beyer's papers:
 
  "It might be said that radiation pressure is a phenomenon that the
   observer thinks he understands — for short intervals, and only
   every now and then”

I remember reading the paper that comes from a very long time ago,
and that was what inspired my remark about radiation pressure being
one of the more elusive topics in acoustics !
