Theorectical Physics: The ‘Constructor Theory’ Of Oxford’s Chiara Marletto

“Declaring something impossible leads to more things being possible,” writes the physicist Chiara Marletto. “Bizarre as it may seem, it is commonplace in quantum physics.”

Chiara Marletto is trying to build a master theory — a set of ideas so fundamental that all other theories would spring from it. Her first step: Invoke the impossible.

Constructor Theory is a new approach to formulating fundamental laws in physics. Instead of describing the world in terms of trajectories, initial conditions and dynamical laws, in constructor theory laws are about which physical transformations are possible and which are impossible, and why. This powerful switch has the potential to bring all sorts of interesting fields, currently regarded as inherently approximative, into fundamental physics. These include the theories of information, knowledge, thermodynamics, and life.

Political Analysis: Is Taiwan Part Of China?

If countries were people, the relationship between China, America and Taiwan would be a love triangle like no other.

Taiwan is by some reckoning the most dangerous flashpoint between China and America. Though Taiwan is in most respects an independent country, China insists it is part of the People’s Republic and is not ruling out taking the island by force. If that were to happen it could ignite an all-out war between America and China. This film explains how this precarious situation came about and how might it play out.
