Understanding Physical Systems

These are short presentations I've given over the years on topics that I found interesting.  They are informal, educational, and accessible to a physics audience . They emphasize basic understanding and simple mental models, mostly mimicing how I learned to think about these systems. 

Controlling small quantum objects

Phenomena in physics

Simplifying Theoretical Formalisms

Physics is full of baggage and complicated terminology, some topics more than others. These are my attempts to cut through the noise. 

Interactions in quantum mechanics

Statistical mechanics
