I I think that's kind of a rel a relative division.
Um physics studies the world on lots of energy scales.
Um
Some of the systems it studies have relatively few moving parts and can be studied in a relatively complete way.
Some of them have an extremely large number of moving parts and have to be studied by
uh the techniques of statistical mechanics and other sort of approximative methods.
Um, generally speaking, we tend to use fundamental
to refer more to the first sort of physics than the second.
But
In the strict sense that philosophers tend to talk about, they tend to mean fundamental physics.
I I d I don't like this usage, but to go with it they tend to use fundamental physics to mean something like that branch of physics which is concerned
with, you know, the most f even this is dodgy for activity, but the most fundamental constituents of nature.
Nature exactly without approximation on
All energy scales.
And in that sense of fundamental physics.
No fun there is no theory of fundamental physics that has any experimental support.
Mm-hmm.
String theory genuinely is aspirationally a fundamental theory in that sense.
String theory aspires to be a theory of everything in the classic sense.
Um not not in the sense that it will predict all the interesting goings on.
