• Quantum Gravity
  
• Fundamental Physics
  

The first is about Quantum Gravity (mostly string theory and things like toy models inspired from it), and the second is about already empirically established frameworks like general relativity and quantum field theory. I would like to edit these 2 notes forever, unlike below old notes that were specific to a single undergrad semester.

You can find some of my old notes and useful links below.
