## Welcome to Physics 2C, Fluids, Waves, Thermodynamics, and Optics, Winter 2018

You will learn about thermodynamics, fluids, waves, and optics in this course (in that order).

To do well in this course it is important to attend all lectures, discussion and problem sessions, pay attention during them, ask questions when you don't understand, and take notes. Also, to work on the problem assignments every week, to come to office hours especially if you are falling behind, and to read the textbook as well as other books on reserve.
