Graduate & undergraduate, upper division. This course is an introduction to computational algorithms to solve realistic problems in many branches of classical and modern physics, with an emphasis on methods that are directly relevant to current research. In the lecture component, the instructor will develop the theoretical basis for various algorithms and highlight applications to relevant physics problems. In the laboratory component, students will implement the algorithms and investigate applications. Topics may include: numerical differentiation & integration; parameter fitting to experimental data; coupled ordinary differential equations for initial value problems; Fast Fourier Transforms (FFTs); finite-difference and spectral methods for partial differential equations (diffusion and wave equations); Monte Carlo techniques for statistical physics.

Undergraduate, lower division. This course is an introduction to Newtonian mechanics, which is the study of motion of macroscopic objects (at speed\ s much less than the speed of light). Topics include: vector algebra, kinematics (position, velocity, acceleration, linear motion, projectile moti\ on, circular motion, relative motion), Newton's Three Laws of Motion (inertia/inertial frames, F=ma, action-reaction) & the concept of force (weigh\ t, gravity, normal forces, tension, spring forces, friction, etc.), impulse & linear momentum, work & kinetic energy, potential energy & conservati\ on of energy, elastic & inelastic collisions, torque & angular momentum, planetary motion, rigid body statics & dynamics, and oscillatory motion (s\ prings, pendulums).

Graduate level. Introduction to the physics of plasmas, often called the fourth state of matter. A plasma is an ionized gas, a "soup" of positive a\ nd negative ions. Particles are accelerated by electric and magnetic fields; in turn, the motion of ions generates currents and magnetic fields. Be\ cause of the long-range nature of electromagnetic forces, plasmas exhibit "collective" effects. Topics include: what are plasmas, single-particle m\ otion, plasmas as fluids (magnetohydrodynamics), waves in plasmas, diffusion & resistivity, equilibrium & stability, kinetic theory, and nonlinear \ effects in plasmas. Applications include both laboratory (fusion research, laser produced plasmas, propulsion systems) & geophysical/astrophysical \ plasmas (geodynamo, solar wind/magnetosphere interactions, star formation, pulsars, intergalactic medium).
