**New study highlights importance of context to physical theories**

In doing so, we consider the framework of general probabilistic theories, a unified tool that comes very handy for constructing generic physical theories.” ” In his study Contextuality of General Probabilistic Theories Dr Shahandeh examines what structural property of a theory like quantum mechanics makes it prone to contextuality. He said: “In this work we determine the geometrical characteristics that give rise to either noncontextuality or contextuality of a physical theory. ” Physicist Dr Farid Shahandeh said: “Imagine a physical theory whose explanation for the trajectory of an apple falling from a tree differs for Gala and Pink Lady. He added: “The techniques and results obtained in this work can be extended and applied to quantum information processing tasks that aim for non-classical advantages.” But, we know that if we try to interpret quantum mechanics in classical terms, it becomes contextual, and consequently counterintuitive. A Swansea University scientist’s research into the geometrical characteristics of a physical theories is highlighted in a new paper.
