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...

Das Higgs-Teilchen und das dazugehörige Higgs-Feld sind für unsere Welt und den ganzen Kosmos von grundlegender Bedeutung. Das Higgs-Feld, welches das ganze Universum durchdringt, sorgt dafür, dass Elementarteilchen Masse haben. Erst wenn Elementarteilchen Masse haben, können sie sich mit...

Logo World Conference on Physics Education
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...
Higgs potential and fundamental physics

Physics associated with the Higgs potential is rich and very interesting. I
believe it deserves efforts aimed at explaining it to high school students even
though the subject may appear complex, even formidable at times. Before we
embark on this task we might benefit from an...

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...
