OK,
But I am sure that any deciphering is a systematic rather than a random
process. I can however agree that when such a systematic process is fueled
by drinks, some random mental leaps might play a role.
This fact, unfortunately, does not help in solving this terminology
problem - at least not here.

Lubo

In Russian we use an equivalent to 'structure decipher'.
Sometimes, however, this is really 'structure solution' when we apply vodka in
the process ;)

Hi,
I feel I have a problem with terminology. What's the right
nickname for
the method of structure solution from powders, which instead
of analyzing
electron (nuclear) density shuffles atoms or molecules
around a cell and
compares experimental and calculated patterns ? It could be
well used also
for single crystal data, I know, but it is not routinely
done (yet ?).
I remember that colloquially used phrase "structure solution
in direct
space" woke me up several times during plenary lectures at
several
conferences. What are we having in direct space ? IMHO just
electron
(nuclear) density. Its FT is our diffractogram so that if we
fit
diffractogram, are we still in direct space ? Of course,
reciprocal space
is a pure math and diffracted beam is quite realistic (BTW,
are
there photons also in reciprocal space :-) ?). But in which
space are we when doing any
crystallographic calculation ? OK, OK, you know what I am
asking ... no
bad jokes, please.
May I ask for your 2 cents ?
Thanks,
Lubo
