2 groups exist

[Alexandre Urzhumtsev/Ourjoumtsev <sacha@lcm3b.u-nancy.fr>]

hello,

I completely agree with the opinion by Tassos. These 2 (or more) groups
exist. However, the advantage of mathematics is that is it the same common
language for very many applications. The same for informatics, algorithms
etc. And I see how people from one of these group lack an experience and
the knowledges already available in the complementary group. And this makes
me warry a lot.
	We are always speaking about too much specialisation in science. But why
do we push it even in such small things ? Why do we want to make more and
more narrow sub-sub-sub-sciences ? Should we learn more from the people
next door to our ? I remind you that this is the goal of conferences - to
share your knowledge.
