# Lectures & Recitations

Take the course at your own pace. A "week" below can be spread out to a longer period, e.g., 10 days or two weeks, to fit your schedule. We recommend you follow the chronology of how we actually taught this class: with alternating lectures and recitations.

The teaching style for this course is rather unique. We believe learning is best done by engaging with the material at multiple levels – from abstract math to practical demonstrations. With this in mind, the class is organized into "lectures": where we introduce broad concepts, developed using basic examples and lots of in-class demonstrations to show you the physics live-in-action. The other aspect of our teaching is "recitations", holistically intertwined with the lectures, where we explore ideas in further depth, look at various examples and subtleties, and talk about interesting applications along the way.

The course is ideally covered over a span of 10 weeks, with two lectures and two recitations each week. The first lecture each week makes heavy use of demonstrations to introduce and illustrate topics of instruction. The second lecture is more analytic, deriving and exploring the basic results in detail. The recitations provide further analysis, sometimes with additional demonstrations, as well as provide a forum for our students to clear up points of confusion.
