## Welcome to Physics 4B, Fluids, Waves, and Heat, Spring 2018

You will learn about fluids, thermodynamics, and waves 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.

## Announcements

• You can pick up your final this Friday at instructor (half) office hour 1:30pm to 2pm.
• Final histogram is posted

• For final exam you can have 1 sheet of formulas (both sides). Some words next to the formulas are ok. No figures, no examples. PLEASE BE ON TIME. Please bring a new blue book, a calculator (preferably non-graphics-non-programmable), and a pen. Constants will be given. Please note that calculators that are also communication devices (e.g. iphone with a calculator app) are strictly forbidden. Please write all your work in your blue book, no credit will be given for results without justification

## Course Format

HOMEWORK ASSIGNMENTS: Problems from the book will be assigned every week, solutions will be posted on the web page. To fully understand the material, you should work most of the problems on your own without help of the solution key. Homeworks will not be graded.
QUIZZES: Closed-book quizzes will be given on alternate Mondays, the first one on April 9th. There will be lectures on the other Mondays. There will be no make-up quizzes.
COURSE GRADE will be computed from the average of the 5 quizzes (50%) and the (closed book) final exam (50%). If you need to miss a quiz due to unavoidable circumstances AND notify the instructor beforehand, the weight of the final and other quizzes may be adjusted accordingly.
