Semester:Spring 2021
Instructor: Cemal Yalabık
Office: Room SA-228 Phone 1316
This will be a 100% online course! The best way to contact the instructor out of class is through email at and arrange for a zoom meeting if necessary. My Office Hours this semester will be Fridays 12:30 - 13:30 and I would prefer to have the meetings during those times, but we can arrange other times if necessary.

Introduction to Quantum Mechanics by Griffiths

Homework for this week: There will be weekly homework assignments for this course in this course.

You can view your grades through the Stars system.

FZ Policy
In order to get a D grade from this course, a student must show an overall achievement level of %. An important part of this achievement must be accumulated through regular studying, before taking the final exam. The student must demonstrate this by accumulating sufficient pre-final points from the first and second exams such that (s)he will not need more than twice this pre-final performance in the remaining assessments (i.e. Homework+Quiz+Final) to bring the overall average to %.

Therefore a student cannot get a D grade if the pre-final achivement level is below % from the first and second exams .

This means, a student will receive the FZ grade (and will not be able to take the final exam) if the average is lower than % from the first and second exams! (If the grade is , the student will need to receive at least from the remaining assesments [Homework+Quiz+Final] to get a D grade.)

Relevant links:

Now that you have learned quite a bit of Quantum Mechanics, you can use this background to expand your knowledge in basic physics. In particular, there is a large amount of scientific presentations available on the internet. I am listing links to some of them below. Don't worry if you do not understand everything in the talks - neither do I. But it will give you an idea about what questions exist in fundamentals of physics, what scientists think are interesting topics to work on and what methodologies are used.
