for what it is worth: physics is not easy, never was, never will be. the painfully slow invention (or is it discovery?) of the mathematical machinery required to understand physical phenomena is one of the most astonishing feats of the human brain. In my view it sets it apart from anything remotely "AI"-sh. Starting with early calculus, to differential geometry, Hilbert spaces and whatnot, the brain doesn't fit models to data, it is making up categories and concepts (new classes of metamodels if you wish) as it goes along (as improved experimental devices augment our sensory inputs). To cope and explain these totally indirect information flows the brain conjures up symmetries in invisible abstract spaces, invariants and visual imagery from alien internal worlds, pursues "thought experiments" to restore sanity... Machine learning style fitting of "model" to data is just one of the final steps. Important but hardly defining the process. The "AI" folks oversold their goods by a breathtaking factor and are now exposed to the entire planet. No physicist will ever be able to bail you out :-)
