There is no crisis in Physics. Physics is doing well, thank you. The crisis is in the minds some people who do not get the idea. The reason for this is that it has gotten hard and takes longer to get the idea.
QM works as well as when it was started. So does Relativity. There were problems with QM in terms of interactions so Q field theory was worked out by Feynman and Schwinger. There were strange kinds of relations between mass and spin so strings were suggested. [Spin seems to increase with mass squared. Regge trajectories.] Gravity was a problem and it turned out that strings have answer to the problem of gravity.
The thing is to know Physics today takes a lot of time and effort. Lots of "Girsa" [saying the words and going on] and lots of Iyun (Review of one section many many times.]
