In summary, scientists are working to axiomatize physics, but it is still a work in progress. There are many principles that must be accepted as true before physics can be axiomized.

"Can Physics be Axiomized?"

The question "Can physics Be axiomized?" is one of Hilbert's 23 unsolved problems : http://www.andrews.edu/~calkins/math/biograph/199899/tophilpr.htm

What are your ideas on this particular one?

1) Relativity and relativistic Em have been axiomatized.
2) Discrete particle quantum mechanics, including Dirac's relativistic one have been axiomatized.
3) There exists a set of axioms, the Wightman axioms, for Quantum Field Theory, but AFAIK it has not been successfully applied to gauge field theory, such as Yang-Mills theory, which is the type of theory that supports the Standard Model. Axiomatizing Yang-Mills theory would settle the questions about it for which a Clay prize has been offered.
4) Thermodynamics is an axiomatic system.
5) Work goes on to axiomatize string theory and quantum gravity.
6) We don't have a "final theory" yet, so the question of axiomatizing it is moot.

Unlike mathematics physics is concerned also with the truth about natural facts,being guided by empiricism,namely the correspondence theory of truth.Thus physicists seek first the correspondence between their enunciations about the world and the observed facts to consider them objective knowledge.Unfortunately there is no way to begin from a (known with certitude) true set of [premises] and,step by step,to deduce true theories,larger and larger in scope,about the world;there is no way to find some first,true, principles,the dream of Aristotle.This is why science has to reside on some basic assumptions,self evident,accepted without demonstration,in order to assure itself consistency in the most economic way (as indicated by the principle of sufficient reason,the base of human rationality).The big difference from mathematics,since physics account for natural facts,is that,in doing so,we do not consider them less fallible,that is if some new data contradicted them then they would be discarded.

Apart from those basic assumptions axiomatization in science is possible (as a matter of fact it is very often applied in practice in different sciences) in the form of principles from which,in conjunction with other premises (enunciations accepted as representing objective knowledge,not falsified yet,or even other principles) we can deduce novel predictions,corroborated later,about the world.For example,as others have already pointed out,Relativity rest on such principles,there are many other examples.But again it should be clearly stressed that they are considered fallible,if Relativity in the current form would be falsified then the principles should at least be altered (or perhaps other auxiliary assumptions should be introduced) if not dropped altoghether.Thus we do not deal with a fixed scheme buidling over some [more] basic levels,not even the basic assumptions are exempted from being discarded.

[PS]Though Godel's incompleteness theorems put serious problems for science (since artihmetics is included in the set of enunciations accepted by science) this does not mean that a 'theory of everything' cannot be complete.Indeed there are variants of arithmetics which are complete and currently there is no reason to think that the complete set of Peano axioms [is] needed to obtain such a theory.

1. Can all of physics be reduced to a set of axioms?

Currently, it is not possible to axiomatize all of physics due to the vast complexity and diversity of physical phenomena. However, some fundamental theories such as quantum mechanics and general relativity have been successfully axiomatized.

2. How do axioms in physics differ from those in mathematics?

In mathematics, axioms are statements that are assumed to be true without proof, and they serve as the foundation for building logical arguments. In physics, axioms are used to describe observed physical phenomena and make predictions about their behavior. They are based on empirical evidence rather than abstract reasoning.

3. Are axioms in physics subject to change?

Yes, axioms in physics are not set in stone and can be subject to change as new evidence is discovered. For example, the discovery of the Higgs boson led to the modification of the Standard Model of particle physics.

4. Can axioms in physics be proven?

No, axioms in physics cannot be proven as they are the starting point for understanding the physical world and cannot be derived from anything more fundamental. However, they can be supported or falsified through experimental evidence.

5. How important is it to have a complete and consistent set of axioms in physics?

Having a complete and consistent set of axioms is crucial in order to accurately describe and understand the laws of nature. Inconsistent axioms can lead to contradictions and inaccuracies in predictions. However, it is important to note that axioms are always subject to refinement and modification as our understanding of the physical world evolves.
