In an interview for the BBC, Nobel Prize-winning scientist Professor Peter Higgs has revealed he did not know he had won the award until a woman congratulated him in the street.
Professor Higgs, who does not own a mobile phone, said a former neighbour had pulled up in her car as he was returning from lunch in Edinburgh.
The 84-year-old emeritus professor at the University of Edinburgh was recognised by the Royal Swedish Academy of Sciences for his work on the theory of the particle which shares his name, the Higgs boson.
