    Einen Teilchenbeschleuniger zu bauen, der noch grösser ist als der Large Hadron Collider am Cern, ist nicht abwegig. Bis anhin tun die Physiker aber noch viel zu wenig, um die Öffentlichkeit davon zu überzeugen.(Building a particle accelerator even bigger than the Large Hadron Collider on Cern is not out of the question. Until now, however, the physicists are still doing too little to convince the public.)

    Si les projets post-LHC dont nous allons détailler les enjeux au fil de ces lignes, nous laissent entrevoir de nouvelles découvertes dans les prochaines décennies, la Chine et le Japon sont eux aussi dans les starting blocks. (If the post-LHC projects that we will detail the issues along these lines, let us see new discoveries in the coming decades, China and Japan are also in the starting blocks.)
