Do physicists know the fundamental structure? They have some mathematical approximations that work for some measurements. They can make some predictions in some areas, but the same approximations break down in other areas. So the fundamentals aren't 'known'.
Some think measurements is engineering. So are the physicist that focus on building an apparatus to measure a theory, they are engineers? So only the theoretical people doing math are physicist? Even thought at that point they are only doing math?
Is Information Theory and Entropy a Computer Science subject or a Physics subject?
Physicists have learned quite a bit about the fundamental structure of the cosmos in the last 500 years. We can get into philosophical quibbles over what is knowledge and the relationship between approximations to reality, but we have clearly developed a very rich understanding of how the world works. A lot of the fundamentals are very clearly known. Entropy and statistical mechanics have been part of physics for 150 years and have clearly enhanced our understanding of the universe. Claude Shannon’s work definitively helped us understand the world more deeply. I think deep learning is interesting but it would be a stretch to claim that this has enriched our understanding of the universe by a large margin. Definitely not as much as Shannon’s work.
Funny, on same day there is a post from this guy that seems to think the nature of reality is computation. That the fundamental structure is computation and cellular automata.
Maybe it isn't 'machine learning' but definitely the lines are blurring between physics and other fields of information.
