Just because you don't understand modern physics does not make it useless. Do you understand how nuclear magnetic resonance works? It's a good thing your MRI machine will still work regardless of your understanding. Do you think most people have any idea how transistors store a state value? These examples, along with countless other discoveries made by physicists, should make it pretty clear that your understanding of physics (and mathematics) in no way affects its usefulness or value.

The reason for pursuing physics is not to bestow new information on the general population, that's a completely different area called physics education.
