To
remind you both, take the time to (re)read the title of this thread and the
questions raised under it to begin with ...
Going
wild off-topic seems a national sport here anyway ...

The
debate "natural" versus "formal" is everywhere and I copy below one intervention
I made in another forum about it lately.
But
the notion of cultural biasis *ev

- once again - the one I was about in starting the thread

I think we have there radically different views of the
world. Do you
consider the prose - somehow standardized or ritual, even if in natural language - used to articulate discourse in mathematical publications, or for that matter in any scientific publication, and in standards specifications like W3C or ISO, only a "social paint", and the peer review process, based on those publications, only diplomatic gesticulation, with no real importance in the efficiency of the tools? I strongly disagree. The process of validation and social agreement is essential for the construction of collective knowledge references. Without that process, there is no consistent knowledge communities, the same way that there are no consistent social right-driven communities without aknowledged (written) laws and regulations, elaborated through peer-review process of the same type. There is no fundamental difference, IMO, between the human process leading to the elaboration and validation of a social law and the one leading to the adoption of a new standard syntax or mathematical tool or so-called "physical law". It's all about forging a collective tool through intersubjective agreement. And, like it or not, all those processes are referencing to TEXTS. Every bit of mathematical reference is grounded on definitions (text) axioms (texts) and theorems (text) and weird notations (often difficult to serialize indeed). Even if mathematical objects are pluridimensional, geometrical, graphical, functional ... what makes the meaning and efficiency of these objects and make the mathematical construction consistent is that text metalevel. Indeed, out of my experience as a maths teacher for more than twenty years, what I consider to be the real difficulty of students in mathematics, what is stopping most of them at a very elementary level is not the comprehension of the mathematical objects, algorithms or representations, but the comprehension and mastery of this natural language metalevel. Moreover, like natural language, syntax of mathematics is often more driven by historical contingent constructs than formal or logical constraints. I can point you at many mathematical notations which are known to be inconsistent, but are kept going on because everybody agrees on their implicit context and nobody wants to rewrite all the books. Ask the first programmers of automated calculus the hard time they had with trigonometrical notations for example, which are completely inconsistent with other algebraic notations. Ask any maths teacher the hard time it is to explain to high school children the consistency of things like: In a(b+c) a(...) means a multiplication, and (two years after): in f(x), f(...) means a function! Every student in maths and science has to go through all that language contingencies and notation inconsistencies, and master the historically built collective knowledge and agreements. So he/she has to become somehow a "text-editing-bigot". In trying to build consistent and efficient references for Topic Maps, we are confronted to the same problem of constructing some agreement. We have a syntax, built out of a mixture of formal and logical arguments, historical consensus (barely a consensus so far), and available specifications - namely XML. We have OTOH mathematical and graphical tools, and computer processes and languages. We try to build something consistent with all that material to agree about. Where and on what ground will we construct this consensus, if not at some natural language metalevel? Don't forget we'll have to communicate afterwards to the rest of the world, every administrator and editor and end user, what we are about. |
