Trinity physicists have potentially answered the age-old question of how Santa Claus manages to deliver billions of presents every year. The answer, they say, lies in quantum physics. Prof John Goold and Dr Mark Mitchison – both physicists in Trinity – say that Father Christmas may be using quantum mechanics, which allows Santa, his reindeers and his sleigh to be in many places at once. This is called superposition. In a press statement, Goold said: “Experiments show that these weird states describe tiny things – like atoms – but also much larger things too. In fact, an important part of our job as physicists is … Continue reading Santa Uses Quantum Mechanics to Deliver Presents, Say Trinity Researchers
