A (Gentle) Introduction to Holographic Duality: Part 1

Here -- in Part 1 of a two-part lecture -- I give a gentle introduction to the idea in theoretical physics called holographic duality. The target audience is undergraduate students in physics, but I think it should be accessible to anyone with some exposure to basic ideas in physics (like thermodynamics and entropy).

Part 2 of this lecture is here:    • A (Gentle) Introduction to Holographi...  

Holographic duality -- also called AdS/CFT, or gauge-gravity duality -- states that certain theories of quantum gravity are exactly equivalent to systems of particles with no gravity, but living in one lower dimension. In this talk I motivate these ideas by explaining some peculiar things that happen when you think simultaneously about quantum mechanics, black holes, and thermodynamics.
