The question about saying that learning math and physics is a part of learning Torah [according to those rishonim [Mediaeval authorities] that hold that way] is where is the numinous [holy] aspect of it? Answer is that there are paths towards holiness that have been revealed only after great tzadikim opened them up. They were not just hidden before that but in accessible. Sometimes you need a tzadik to go into the jungle and carve out a path before others can follow.
At least I can depend on the Gra who held "One who lacks knowledge in any degree in any of the 7 wisdoms will lack in Torah knowledge a hundred times more." So at least to that degree math and physics are important. [That quotation is from the translation of Euclid done by a disciple of the Gra in his introduction.]
[You can see this opinion in the Obligations of the Heart [shar habehina chapter 3 where he makes a distinction between learning about the spiritual aspect of things and the actual learning of their physical workings. And both are necessary to learn.]
