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:

  1. What we currently know...
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...
