In summary, David Deutsch's paper "Constructor Theory" discusses the concept of which physical transformations can occur and which cannot, and why. He argues that this theory has the potential to unify various fields of physics and solve problems, and that the second law of thermodynamics may be more of a philosophical law than a scientific one. However, the paper has been criticized for being filled with useless definitions and not being scientifically rigorous.

Constructor Theory
David Deutsch
(Submitted on 28 Oct 2012)
Constructor theory is the theory of which physical transformations can be caused to happen and which cannot, and why. Several converging motivations for expecting it to be a fundamental branch of physics are discussed. Some principles of the theory are proposed and its potential for solving various problems and achieving various unifications is explored.

20 pages in and it's all useless definitions and garbage, as expected from what is apparently a philosophy department?

I might not understand Deustch's talk in Edge, but it seems he argues that the second law of Thermodynamics is a philosophical law and not a scientifical one, cause we can always argue for some invisible force acting there to correct for violation of the second law. (It's in 14-15 min).
 

1. What is Constructor Theory by David Deutsch?

Constructor Theory is a theory of physics proposed by physicist David Deutsch, which seeks to explain the fundamental laws of nature in terms of what physical transformations are possible and impossible.

2. How does Constructor Theory differ from other theories of physics?

Constructor Theory is unique in that it focuses on the physical transformations that are possible, rather than the fundamental laws that govern them. It also has a more philosophical approach, seeking to explain why the laws of physics are the way they are.

3. What are some practical applications of Constructor Theory?

Currently, there are no direct practical applications of Constructor Theory, as it is still a relatively new and developing theory. However, it has the potential to revolutionize our understanding of the universe and could potentially lead to new technologies in the future.

4. What are the criticisms of Constructor Theory?

Some critics argue that Constructor Theory is too abstract and lacks empirical evidence to support its claims. Others argue that it is too philosophical and does not provide concrete predictions that can be tested.

5. How does Constructor Theory relate to other theories of physics, such as quantum mechanics and general relativity?

Constructor Theory is still in its early stages and its relationship to other theories of physics is still being explored. However, some physicists believe that it could potentially provide a more fundamental and comprehensive explanation of the universe, incorporating both quantum mechanics and general relativity.
