Dear Karl,
Yes I can hear you.
About symmetry, I shall soon send you an explaining email, privately,
because I do not want to bother the FISers with long explanations
(unless I am required to do it).
However, I confess that many posts that I receive from the FIS list
are very hard to read, and ofte

Dear Arturo,
Sorry for my naive question, but isn't the named set theory something
different from the set theory?

Dear Loet,
Variance is a parameter which can be computed for the distribution of
any real random variable having a finite moment of order 2.
It includes Normal, Binomial, Poisson, Exponential, any distribution
with bounded support, etc.
However, some statistical tests about the variance assume norm

Thus, deciding to classify a publisher as predatory or not is
difficult, and the result of this decision can hide a complex reality
that should be examined.
Your opinions are welcome.

Dear Dick,
Replying to the following two questions may help:
(1) Is there information in the situation there is no data ?
(2) If yes, an example would be great; If no, is there information if
no data is conveyed ?

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
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.
That's ok with me: I like transdisciplina
Dear FISers,
I thank very much Robin, Xueshan, Stan, and Karl for their examples
of information, that I summarized below:
*** Robin:
Of course, there is no "law" or formula that relates a bit of
information to, say, quarks, spin, or whatever. These are different
ways of looking at the same thin
Dear FISers,
Many thanks to Xueshan Yan for these three examples of cheminformation.
I agree that among the various cheminformation concepts, some are technological.
E.g., the Infonortics conferences (the 2011 one held in Barcelona:

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
concrete
Dear Loet,
Thanks for your very good reply.
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.
However, starting from data (and databanks), we can extract knowledge
Dear Gavin,
Information Theory is a specific subfield of Probability Theory
applied to Information Sciences. It was used in the 70's in
cheminformatics by F. McLafferty (mass spectrometry), A. Dijkstra
(infrared spectra databases), etc.
Would you reduce Information Science to Information Theory ?
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
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

close relation of information science(s) with
databases, in general. If not, where is information ?
May be in our head, and not only it can be communicated (e.g.,
teaching), but also it can be stored (not trivial to do properly).
During centuries it was stored in books. Now, it is in computer

the vendor needs your money, and it is why he delivers his "information".

Dear Marcin,
The situation is different for information and for entropy.
Bob discussed about entropy, and I agree with his view.
However, despite that the term "information" is used in information theory

one of these models is applied to physical science, the other is applied
to communication science.
