Claire and Christophe are two compatriot postdocs at the university of Oslo, mathematician for her and physicist for him. Christophe works in the same institute as Olivier, where geologists and physicists share very good time and good fun, even if sometimes they don't understand each other. By proposing himself to take care of the website, Christophe probably did not know the huge task he accepted to face after the messy Olivier. Thanks again, and we wish you very good luck!
