Example of a question
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...

The Universe as a glass of beer

This talk was given at TEDxOporto 2016 to a large, general public audience.  It attempts to address the question, posed by a young student: "How do we measure what we can't see?" The talk addresses this in three parts:

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.
