Particle physics probes the basic building blocks of matter and their interactions, which determine the structure and properties of the extreme diversity of matter in the universe. The web portal makes the fascinating research understandable to an interested public.more

Modern physics relies on an elegant «Standard Model of particle physics», a quantum field theory based on three symmetries and a symmetry breaking. This theory describes and explains magnificently all experimental results obtained so far. With the discovery of the Higgs particle in 2012 at the Large Hadron Collider at CERN, the last missing piece of the Standard Model has been experimentally confirmed. Experiments at CERN and at other international laboratories now continue to test the validity and limits of the Standard Model in ever widening scope. However, for a comprehensive understanding of the laws of nature a theory beyond the Standard Model is needed, which should include gravitation and explain the presence of dark matter and dark energy in the universe.

Quantenphysik Vortrag NGT
  • Lecture

100 Jahre Quantenphysik - warum ist das Themenfeld aktueller denn je?

Die erste «Quantenrevolution» erfolgte Anfang des 20. Jahrhunderts. Was passiert heute, rund 100 Jahre nach den bahnbrechenden Erkenntnissen von Max Planck, Albert Einstein, Werner Heisenberg, Erwin Schrödinger und vielen anderen?
