Nobel Prize in Physics

Swedish

During this week before the Nobel Prize ceremony in Stockolm and Oslo, December 10, we present the Nobel Prize winners and what they have received the prize for.

The Nobel Prize in Physics is awarded to François Englert and Peter W. Higgs.It was in 1964 when the two of them, independently of each another suggested a theory on how particles acquire mass. In 2012 the theory was confirmed by the discovery of the so called Higgs particle at CERN laboratory in Switzerland.

The importance with the discovery is that the mechanism for how particles acquire mass is a central part in the Standard Model in physics. This model describes how the world is built. According to it all things consists of matter particles which are governed by force particles which make everything work as it should. The Standard Model needs just one more particle, namely the Higgs particle, to be complete. Like all matter particles have their matter field the force particles have their force field and Higgs particle has Higgs field. This field can be described like a sort of vibration which gives the other particles mass, which in turn is important for how atoms and moleules are built and held together. If Higgs field wasn’t there all materia would collapse.

CERN has been working to find the Higgs particle. Last year, July 4th 2012, they announced the discovery of the Higgs partile and Engelrts and Higgs theory was confirmed.

François Englert is born 1932 in Etterbeek, Belgium. Today he is Professor emeritus at Université Libre de Bruxelles, Belgien

Peter Higgsis born 1929 in Newcastle, Storbritannien. Today he is Professor emeritus at University of Edinburgh, Storbritannien.
