* If the final class average falls below 70%, a curved scale will be used, with the class average set at or near 78%.
Homework Policies:
Homework will be due in class at the second class meeting after it is assigned. Late homework will be subject to a penalty of 10% per day unless an extension has been arranged with the instructor prior to the due date. No late homework will be accepted after a solution set has been made available.
Homework must be legible, with questions answered in numerical order, and stapled if more than one page long. Please: no spiral-bound paper, or pages connected by folding the corners. Students may consult with one another on the homework, but what is handed in must be each student's original, individual work. Homework assignments (or portions thereof) from different students that appear to have been copied or that otherwise appear to be identical may be returned to all the submitters with zero credit.
The purpose of the homework is to illustrate, apply, and reinforce key topics, not to serve as dry runs for exams.
Exam Policies:
Students may bring pencils or pens, erasers, calculators and straight edges to the tests. The mid-term and final exam will be open-book and open-notes. Computer/Pad is also allowed. However, internet and communication softwares/devices in any form are not allowed. During the 3 h exam time, students are not allowed to discuss/consult with anyone and what is handed in must be each student's original, individual and hand-written (hand-drawing) work. If there is any hint that the content is copied, zero credit will be given.
Mid-term exam will cover the lectures and reading assignments from the preceding parts of the course. The final exam will cover material from throughout the course. Some of the test questions will be similar to the homework problems in style (i.e., short-answer; calculations; explanations of concepts), but some questions will require the student to apply previous material to new situations.
Unless for definitions, memorizing (complicate) equations is not required because one can always look it up. However, understanding the correlation between factors and the physics behind is crucial.
COVID-19 Measures
It is pretty much impossible for me to wear mask and talked non-stop for three hours - it is difficult to breath and the mask will keep shifting so that I have to keep moving it back instead of focus on teaching. Therefore, I will not wear a mask when teaching but will try to keep distance as far as possible. For those who are worried, please feel free to use distance learning by watching records. The date of slide (PDF file) and video (last one in each section) uploaded is noted on the website. Nevertheless, if you have questions and we do one-on-one discussion, I will follow CDC guidelines to wear mask if it is required.
For exams, if we are still required not to gather in classroom, I will send out questions via e-mail on 2:20 pm. Hand-write your answers and staple pages together following the sequence of the question. No credit will be given to copied or out-of-order content. Please drop your work (with homework) at the departmental office before 5:30 and late submission will not be accepted. I will try to collect them for grading ASAP.
Syllabus
Lecture topics, readings, and dates of homework assignments are subject to change and slides may be updated as we go along. Tests will cover the lecture content and the reading assignments.
