Where do we live ? What are we made of ? Why are we here ? When did it all start and when is the end ? A key for possible answers to these vital questions of life may lie in a captivating connection of an infinitesimally small and an immensely big. Physicists are persistently banging on the door...

DIY cloud chamber material

Particles coming from the universe are crossing the earth all the time – they are harmless but invisible to us. Cloud Chambers are detectors which make the tracks of the particles visible. Some decades ago these detectors were used at CERN in the first particle physics experiments. The following...

A Question of Survival

This presentation was given at TEDxTUM 2015 in front of a large public audience and was recorded and published on the TEDxTUM site, as well as on their YouTube channel.  It attempts to answer the question of why we do basic research by describing it as a necessary facet of human survival.
