Physics is a hugely successful branch of science, but there are some things it has trouble getting a handle on. It is a bit hazy on some of the things we learn about in the physics classroom, such as temperature, heat and work. It has trouble linking up with the science that describes life, and it can't define one of the most important features of life, namely information. When it comes to things like consciousness and the ability of conscious beings to make free choices, the fundamental laws of physics don't offer any clues at all.
This is why physicists from the University of Oxford have developed a new framework for looking at the physical world, called constructor theory. In these articles we explore the theory and look at some of the problems it may be able to help with.
