liudr:
Not interested in your particular branch of physics.
I don't like to think that physics (or science) really has distinct "branches". Of course, people work on different subjects and total reductionism doesn't work in parctice (which is why these branches look very different), but, unless proven otherwise, it actually all boils down to excitation of fields (particles) behaving in a certain way (via fondamental interaction(s)), that can be mathematically described with a lagragian (which is not yet completed, if ever, but there's hope). Now, it turns out that, in suitable conditions (low energies, many degrees of freedom, etc), the emerging phenomenas can be described without having to resort to all the standard model artillery. I would also add that many of the "branches" of physics fruitfully borrow ideas from each other.
But, that's only my (probably biaised) opinion
