Cosmology Class – Teaching Assistant
I served as a Teaching Assistant (TA) for Prof. Jounghun Lee's advanced undergraduate courses in the Department of Physics & Astronomy at Seoul National University. These courses represent some of the most advanced offerings in the astronomy program, requiring extensive prerequisite coursework in physics, mathematics, and astronomy.
The instructors requested me for these courses. Teaching assistants in the department are normally assigned at random. For all three of my TA appointments (these two courses and Introduction to Astrophysics 1), the instructor reviewed the TA roster before the assignment and asked for me by name.
Modern Cosmology
This is the most advanced undergraduate course in the Astronomy program. The course covers key concepts and theoretical background of modern concordance cosmology, including the origin, evolution, and final destiny of the universe.
Understanding the Principles of Information Universe
This course aims to inspire non-astronomy major students (particularly non-science majors) who are curious about popular topics like the multiverse, parallel universe, and simulation universe—collectively called the "information universe." Students learn how these ideas developed, their true meanings, and their implications for consciousness, culture, and society.
