Dear Michel and FIS Colleagues, This will be an interesting discussion, since the core nature and role of information will be involved. Here is just one first point: to me, as a chemist, chemical information is only secondarily an object capable of being formalized, archived, etc. A

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

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. For
