et un poème :

Métaphysique d’Hiver
Bientôt, flotterons-nous dans la musique des sphères ?
Composée, chantée dans la gamme de Pythagore
Parmi les beautés Idéales et les cinq corps
Platoniciens. Nous retrouverons-nous mes frères ?
Selon, dit-on, Démocrite, ce bon professeur
Nos atomes crochus vont-ils se décrocher ?
Et rejoindre le flot, sans cesse renouvelé
Des atomes tombants ? Pour nous trouver mes soeurs ?
Quittant sa tente et son village, le vieil Indien
Prend sa couverture, calme et le regard serein,
Part dans la montagne, rejoindre le grand Tout
Socrate boit la ciguë et philosophe sans cesse.
Saurons-nous retrouver cette antique sagesse ?
Frères et soeurs, dans ce Tout, nous retrouverons-nous ?

Dear colleagues and friends

It is with deep sorrow that we announce the death of Paul Caspi
in the evening of April 23rd, 2012. As many of you know, Paul was
an outstanding scientist, working in the interface between control
systems and their software/hardware realization. Paul's most known
contribution is the development of the data-flow language Lustre,
which takes the block diagrams used by control engineers to model
and simulate their controllers and enriches them with concept taken
from Computer Science (semantics, functional languages, compilation),
leading to the commercial tool SCADE, now used all over the world
for the design of critical embedded software.  Paul was a very
modest person and an original thinker, bringing fruitful ideas to
various domain such as dependability analysis, formal verification,
programming languages and embedded systems. His interests were not
restricted to these domains and extended to Philosophy, Economy,
Society and Culture in general.  For us, his colleagues, he was
a source of inspiration, an example, and the dearest friend. He
leaves a huge void in our community.
