Since this week I am member of two ATLAS experiments … besides being member of the ATLAS collaboration at CERN since 2005, I now joined the ATLAS network of RIPE. While in the former one we try to answer all sorts of questions related to the fundamental physics of the world around us, from the creation and evolution of the universe to the reason(s) for massive particles; the latter one has the slightly less ambitious goal to create a real time map of the internet infrastructure by deploying probes all around the world.
