The Nobel Prize in Physics 1999
The Royal Swedish Academy of Sciences has awarded the 1999 Nobel Prize in Physics jointly to
Professor Gerardus ‘t Hooft
and
Professor Emeritus Martinus J.G. Veltman
for “elucidating the quantum structure of electroweak interactions in physics.”
 |
The structure of particle physics is described using the Standard Model. In this model electromagnetic and weak interactions are unified and together called electroweak interactions. It is theoretical studies of these interactions that have been rewarded with the 1999 Nobel Prize in Physics.
