(Read more...) ProjectsEnergy is Made Up: Interesting Conceptual Discussions around Energy and its Definition. I discuss how energy is nothing more than a helpful ‘bookkeeping method’ for multi-object systems. This leads to interesting discussions, especially for students who have already taken chemistry.

(Read more...) ProjectsHolograms: The Boundary Between Geometric & Wave Optics. We will use the geometric definitions of conic sections to explore the properties of concave, convex, and hyperbolic mirrors and then use this to demonstrate how holography takes advantage of wave interference in order to construct what is essentially a geometric phenomenon.
