So applied math, math, applied math, applied math, and maybe some others.
That makes sense, although I'd argue that at least in the realm of HEP theoretical physics has extraordinarily expensive kit compared to what scientists make. See: The LHC.
Reducing all these fields to mathematics is incredibly reductive. I don't think it's in good faith.
