This course focuses on the fundamentals of fluid dynamics as applied to astrophysical and geophysical systems. We will deal with: a kinematic understanding of fluid flows (how do we describe flows?, the continuum hypothesis, Eulerian and Lagrangian descriptions, etc); a dynamic understanding of fluid flows i.e. the various equation sets describing inviscid and viscous flow derived from conservation laws; dynamic similarity and scale analysis; inviscid potential flows; gravity waves; exact solutions of Navier-Stokes equations; boundary layer formulations; and a selection of more advanced topics such as numerical simulations, compressible flows and some introductory discussions of fluid instabilities, waves, chaos, nonlinear equilibration, and turbulence.
The course is aimed at providing the student with a basic understanding of fluid dynamics, both intuitively and from an applied mathematics point of view.
By the end of the course, you will know how to fly and how to throw a good curve ball in baseball!
The regular lecture material will be augmented with video presentations and experimental demonstrations.

- 11/30: Get your vote in regarding the structure of the class final evaluation! Due 5pm TODAY!!
- 12/01:
- Class voted unanimously to have one last HW instead of an in-class final and to have the grades set by the set of homework grades
- Homework 8 is therefore now set and ready to go! Due in before 5pm on Tues 6th Dec.
