[EN] ATLAS: a titan amongst particle physics experiments - with Christian Gutschow

Meet Christian Gutschow, particle physicist and research software engineer at UCL (University College London, UK). Christian is one of the scientists working on the ATLAS experiment at CERN. And together we try to give you a glimpse of what is going on in this massive experiment that tries to unlock the secrets of matter. Software plays a crucial part in this - and at all levels.
