Nobel in Physics

In this section you will find presentations and explanations of the Nobel annual award in Physics by teachers from the Faculty of Physics.


2020

Roger Penrose, Reinhard Genzel, Andrea Ghez
"for the discovery that black hole formation is a robust prediction of the general theory of relativity"

2019

James Peebles, Michel Mayor, Didier Queloz
"for theoretical discoveries in physical cosmology" and "for the discovery of an exoplanet orbiting a solar-type star"

2018

Arthur Ashkin, Gerard Mourou, Donna Strickland
"for groundbreaking inventions in the field of laser physics"

2017

Rainer Weiss, Barry C. Barish, Kip S. Thorne
"for decisive contributions to the LIGO detector and the observation of gravitational waves"

2016

David J. Thouless, F. Duncan M. Haldane, and J. Michael Kosterlitz
"for theoretical discoveries of topological phase transitions and topological phases of matter"

2015

Takaaki Kajita, and Arthur B. McDonald
"for the discovery of neutrino oscillations, which shows that neutrinos have mass"

2014

Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura
"for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources"

2013

Francois Englert, and Peter W. Higgs
"for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider"
