How to make someone enjoy programming if they don't like the products they make?
I don't normally answer questions that I've voted to close, but I'll make an exception here. I think your quest is doomed. Sorry. 

I also think that pressing is just going to make it worse. Perhaps you can impress that on the mother. 

One can be successful in applied math or physics without programming. It is a helpful tool, but not essential for everything. She can be a success without it, most likely. 

But, the time will, perhaps, come when she needs to use programming to solve some problem that really drives her interest. That is the time that you might be of help, but not now. It is now just a distraction. Wait for the need to become obvious to her. 

In Tai Chi we learn to be soft in our actions and movements. But that doesn't mean they are ineffective.
