This gets us more into the philosophy of science but I've always felt authors
had a right to speculate in the discussion sections of their papers on what it
all means. And speculate even past the information in the actual data (see for
example the wonderfully prescient final lines of the
A memorial to honor the life of Herb Hauptman, co-winner of the 1985 Nobel
Prize in Chemistry for the development of mathematical methods that would
become the basis of direct methods, will be held on Monday 21 November 2011
at 4PM in the UB Center for the Arts on the UB north campus. The
Thanks to all who replied regarding experiences with phantom crystals
(objects with crystal-like morphologies but NO diffraction). The
answers were more fascinating than the original poorly worded inquiry
deserved. Here is a recap.
The observation of phantoms may be rare but not so rare: a
I'd appreciate it if people could tell me their experiences with what I
would call phantom crystals, or ghost crystals. These are objects
that display the seeming morphology of crystals (clear facets, sharp
edges) but do not diffract X-rays AT ALL. I would not count objects
that diffract to 30 A
It may be worth noting that unless rigorous efforts to retard water
transfer are made, most microbatch experiments become vapor diffusion
experiments. A most common situation arises when microbatch is
undertaken in polystyrene containers. Water can then diffuse from the
crystallization droplet
