 You are what they call a source, a massive object somewhere deep in space, sending out its signals.
\textbf{First}, write your name on the front. Then check the info about yourself and start looking for \textbf{detectors} that can detect your messengers. The messengers in \textit{italics} haven't really been seen yet from that source, but we will play as if they have.
Count how many times you've been detected like so: \includegraphics[height=1em]{graphics/countingmarks}. 
And any time you're wondering what all these crazy words actually mean, just ask one of the \textbf{physicists}.

% Vous êtes ce qu'on appelle une source, un objet massif quelque part dans l'espace profond, envoyant un signal.
% \textbf{D'abord}, écrivez votre nom à l'avant. Ensuite, lisez les informations vous concernant et commencez à chercher un détecteur qui peut observer vos messagers. Les messagers en \textit{italique} n'ont pas encore été observés en provenance de cette source, mais nous jouerons comme s'ils l'avaient été.
% Comptez le nombre de fois où vous avez été détecté comme suit : \includegraphics[height=1em]{graphics/countingmarks}.
% À chaque fois que vous vous demandez ce que ces termes un peu barbares signifient, n'hésitez pas à questionner un des \textbf{physiciens} présents.
