     Okay, Guy, help me out here. I have been giving some thought lately
to the influence of structure (micro- and milliscale) on properties of
materials, and I am not convinced that there is a way to distinguish
material properties from the properties (mainly mechanical) that arise in
a given configuration. Am I wrong about that? What about a glass wisker
vs. bulk glass? Does glass have an defineable intrinsic tensile strength
that is independent of whether you happen to make it into a window pane
or a wisker? (If the answer to that is yes, then your explanation should
become an corrigendum to my book, where I discuss this briefly but didn't
know about any such intrinsic properties.)

Best regards,
Marshall Burns
