The Nobel prize-winning British physicist Peter Higgs has died aged 94. The confirmation in 2012 of the existence of the Higgs boson particle, five decades after Higgs had first theorised its existence, paved the way for his 2013 Nobel win. Nicknamed ‘the god particle’, the Higgs boson was part of an attempt to explain why the building blocks of the universe have mass. Ian Sample and Madeleine Finlay look back on the life and legacy of a giant of science.
