  Mathematical physics has many facets, of which we shall briefly give a (very
partial) description, centered around those of main interest for Elliott and us
(Moshe Flato and I). In our case these aspects had as a corollary a variety of
"parascientific activities", in particular the foundation of IAMP (the
International Association of Mathematical Physics) and of the journal LMP
(Letters in Mathematical Physics), both of which were strongly impacted by
Elliott, and Elliott's long insistence that publishers do not demand "copyright
transfer" as a precondition for publication but are satisfied with "consent to
publish", which is increasingly becoming standard. Since this article is
testimony to the huge scientific impact of Elliott, the latter intertwined
aspects constitute the core of the present contribution. The last part deals
briefly with metaphysical and metamathematical considerations related to
axioms.
