Physicists hope that CERN’s Large Hadron Collider, the world’s most powerful particle accelerator, will help answer some of the most intriguing and pressing questions in physics. Steven Weinberg shared the 1979 the Nobel Prize for physics with Sheldon Glashow and Abdus Salam ‘for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including inter alla the prediction of the weak neutral current’.
In this lecture Weinberg discusses the standard model of particle physics – to which he made major contributions – the Higgs boson, the nature of dark matter and the theory of supersymmetry.
Emma Sanders chaired my talk in April at the Edinburgh International Science Festival. A trained astronomer and science communicator, Emma is a press officer at CERN and she gave me a copy of her brilliant pop book Voyage to the Heart of Matter: The ATLAS Experiment at CERN. My 8 and 12 year-olds loved it, but it’s a great book whatever your age.
