LECTURE MATERIALS

Lecture Hours: Tuesday, Thursday 8:30-10:00 am in Phys-150
Office Hours: Thursday, Friday 11 am to 3 pm

Materials for the lecture will usually be uploaded 12 hours before the lecture.
Please print out these lecture materials beforehand - just in case we run into unanticipated technical problems. Please see the Class Log table below.

Please note the important dates:
In-class Term Test #1 on Feb 13 (Thur), and in-class Term Test #2 on Mar 12 (Thur).
Please work around these dates as these dates are now fixed.

Coming Soon
Course materials are intended for private use by the students in this course and they are not for distribution or any commercial purposes. Use at your own risk.

Details of the take-home final exam will be released at LEARN by noon on April 13 (Monday).
This final exam will be due at 3:00 pm on April 23 (Thursday).

All lecture videos are available at LEARN. Please go over these as soon as they become available as these videos will not be available after April 10. The final exam will cover materials not covered in TT1 and TT2. More detail to come at LEARN.

Key to TT2 is avaiablbe below.

All library reserves are available in the Davis Centre Library.
