I am a Masters student of math interested in physics. When I was an undergraduate, I took the introductory course of physics, but it is just slightly harder than high school physics course. To be precise, it just taught us how to use calculus in physics, without involving the higher knowledge of math such as manifold, PDE, abstract algebra and etc. By the way, the knowledge in that course is "discrete", the connections between fields of physics is omited.


My question is, what I should do to learn "real physics" by myself? What books or materials should I read?



How does a Masters student of math learn physics by self?
I can recommend Leonard Susskind's [Theoretical Minimum](https://theoreticalminimum.com):

The name "theoretical minimum" is a reference to the notoriously rigorous [exam](https://arxiv.org/abs/hep-ph/0204295) a student needed to pass in order to study with Lev Landau. See also this [discussion.](https://physics.stackexchange.com/questions/13861/lev-landaus-theoretical-minimum)
