[Phys-L] Wave Structure of Biaxial Crystal

[betwys1 at SBCGLOBAL.NET (Brian Whatcott)]

Jim Bennett is [I think] Curator at the Museum of the History
of Science at Oxford,   He passed along a query to Rete,
  which you may possibly know of.

Professor Denis Weaire of Trinity College Dublin tells me of a find
recently made  in the basement of the Geology Department there:

'a beautiful wire framework, accurately representing the wave surface of
a biaxial crystal, with the "conical" feature particularly apparent.'

He wonders whether anyone else has seen such a model.
