Karl did an interesting remark.
Yes, "circle", "distance", "equal", etc. are terms understood by everybody.
But it often happened that mathematicians attribute definitions to
terms used in a non math context.
E.g., a circle is a set of points in the Euclidean plan lying at a
given distance from a p

This is in fact true. The idea can be better understood if one states: "such

Dear Michel and FIS colleagues,
Thanks for the excellent discussion, so far. The usual conspiracy of
bureaucratic things around me have precluded my involvement in the
important aspects dealt with (and cannot properly refer to the

Thanks Loet, Karl, Gavin, and Robert, for your contributions.
One of the main result of the debate is that, even when focussing on a
specific field such as cheminformation, it is necessary to deal with
physics, mathematics, sociology, and even with biology.

Dear FISers,
Many thanks to Xueshan Yan for these three examples of cheminformation.
I agree that among the various cheminformation concepts, some are technological.

Dear FISers,
Pedro raises several points.
Among them:
1. "Chemoinformatics" or "Cheminformatics" ?
Both terms are encountered. I would say that unless some authority
takes a decision, both terms will continue to be used.
2. Despite I gave an example of what could be cheminformation in a

Dear Loet,

Yes information cannot be found as res extensa, justs as mathematics:
mathematics exist in our head, and can be communicated, can be taught,
etc., but do not exist as concrete objects.

Dear Michel,
Ø Stating that information does not exist may be compared to stating that a

are highly fuzzy, but everybody is sure that it exists.
The problem is here the exist. This easily lead to reification. For

Dear Stan,
I would not insert an 'organic realm' in the hierarchy: it is part of
the chemical realm, but it is broader than expected.
The rules of Organic Chemistry are not universal as the theorems of
mathematics are: many exceptions exist, at least due to the existence
of multifunctional compound
Michel -- Organic chemistry was known to be the most difficult course in
Columbia University. But I got interested in it, worked very hard
constantly, and I achieved an 'A'. But what you say here indicates several
orders of magnitude more difficulty than what I played with in university.

Dear Joe, dear FISErs,
An organic chemist is able to predict a number of properties from the
structural formula, including much about reactivity of the compound.
But as you know, doing that properly is extremely difficult in a
number of cases, because the rules governing reactivity are much more

another system?
