24. Feb 2014 — A narrow staircase, guarded by a bust of grim-looking Ludwig Boltzmann, connects the rest of the world to the cellar of the historic building that houses the faculty of physics. The cellar, dominated by rattling recirculation pumps and dust-covered heating tubes, radiates an almost morbid charm that immediately evokes the famous underground scenes in the movie The Third Man. And the people who work in this underground vault are also in hot pursuit of a double agent — matter. Just as the movie’s protagonists, who used the underground network of tunnels to roam the occupied zones in post-war Vienna, matter can change sides and switch its identity from the wave form to the particle form and back as the situation demands.
