I want to "test" my books before publishing them. I want them to be books suitable for self-study. If you want to study physics and math for free through my books, let me know. I will send you a rough draft of my books. Then, you can study them, and solve exercises there. If you have difficulties understanding the contents in my books or solving exercises, we can either meet each other or chat through internet or Kakaotalk. My books cover high school math, high school physics, calculus, linear algebra, freshman physics, undergraduate physics, general relativity and quantum field theory.
I have a bachelor's degree from Harvard university and a master's degree in physics from Seoul National University.
