The scientist on why studying elementary particles is only one way of explaining phenomena, how the 3D printer could change the world, and her optimism about women in science<\/p>\n

Chiara Marletto<\/a> is a research fellow at Wolfson College, University of Oxford. Her research is in theoretical physics \u2013 especially quantum computation, thermodynamics and information theory. Her broader interests include theoretical biology, epistemology and Italian literature. The Science of Can and Can\u2019t: A Physicist\u2019s Journey Through the Land of Counterfactuals<\/a><\/em> attempts to forward a new foundational basis for physics. It is her first non-academic book.<\/p>\n

You argue for a radically different approach to physics, which you call the science of can and can\u2019t. What does that mean?
<\/strong>It\u2019s a new mode of explanation. Since Newton, traditional physics has been using laws of motion, describing how objects move in space and time \u2013 what happens to an apple if you set it in motion in this or that way. With one exception: thermodynamics. The laws of thermodynamics prescribe the impossibility<\/em> of perpetual motion; by doing so, they put powerful constraints on all<\/em> laws of motion \u2013 those known and those yet to be known. Constructor theory<\/a> follows the same logic, but it extends to a much broader context. We express all fundamental laws as constraints about what transformations are possible and impossible. This apparently simple switch is very powerful. For example, it can capture entities that traditional laws of motion cannot handle exactly: information, the physics of life, and even the mind.<\/p>\n
