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...

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.

My Life As A Proton

The talk was given to a public audience at Le Scandale in Geneva (21 May 2014), during an event called Pint of Science.  The talk tells the story of a proton from birth in the Big Bang to joining the LHC, including all of the embarrassing steps in between.

The discovery of the Higgs boson came at the end of a long journey, where the direction was marked, but the road had to be built. What now? Now the physicists are looking out onto a world we don’t know, where there are no paths, and even the directions to be followed aren’t very clear. They know...
