Spring term, 2021

PLEASE NOTE that tutorials start the FIRST week of classes: January 12 and 13, 2021

Lectures: 11:00-11:50am Mondays, Wednesdays and Fridays in Henn 201.
Classes/lectures start on Monday January 11.
We use Zoom, access via link in PHYS 108 Canvas
I will record lectures in Zoom and they get posted in Canvas after they are processed, typically 2-8 hours after the lecture ends. (sorry I have no control the Zoom processing time).
Tutorials: Tutorials will start Tuesday January 12. Everyone should be registered in one section of the tutorials. I'm at all tutorials, joined by one of our TA's.

Professor: Janis McKenna ( email caveat: I read my email only once or twice during the day and I typically read/answer most email 10pm-1am. Put "PHYS 108" in your email subject header if you want higher priority.
Teaching Assistants: Our TAs Physics are all students who took (and did very well in!) PHYS 108 several years ago: Alex Choinski, Alexandra Qi, and Tim Tueschen
Alex: T2C, class meetings (alex243 at ,
Alexandra: class meetings duofu.qi at

UBC CANVAS: Online UBC Canvas:
I will be posting my lecture slides and course materials in UBC's Canvas. My lecture notes will be posted as soon as I've finished them - usually around midnight the night before each lecture. Class discussion boards, simulations, links to videos and fun resources, announcements, your grades, online weekly chapter reading assessments, weekly homework assignments, course calendar, help/links are all in Canvas.
Janis' Office Hours: Mondays 3-4pm and Wednesdays 2-3pm, in course Zoom room (access via Canvas). I also stay in the tutorial Zoom room immediately following each of the tutorials:
1:30-1:50pm Tuesdays, and 4-4:20pm Wednesdays and I stay for the full hour, 2-3pm, in between the two Wednesday tutorials.
I'm at all of the tutorials and I'm available immediately following each one, afterwards until your questions are answered. You can drop by after any of the tutorials, (not just the one in which you are registered). If none of these times work for you, email me to make an appointment to meet.
TA's Office Hours: We'll set up extra office hours for TAs just before each midterm exam and just before the final exam.
Text: Electronic Text: Fundamentals of Physics by Halliday, Resnick and Jearl Walker.
Available from the UBC Bookstore - I asked for them to order only the electronic textbook, with WileyPlus online homework: (includes full electronic textbook, plus online homework, plus study resources). This all-electronic version is $64.50 from the UBC Bookstore, which is about 65% less than the price of the hardcopy textbook + WileyPlus (which I didn't order). This e-textbook is also 25% cheaper if you buy it from the UBC Bookstore, rather than from the WileyPlus website.
UBC E-Bookstore: PHYS 108 ebook plus WileyPlus from UBC Bookstore.
-- Note: if you want to have a hardcopy, ANY first year calculus-based Physics textbook with the Electricity and Magnetism is fine. Older editions of our textbook are also great, and often you can find inexpensive second hand older editions. If you are in Vancouver, the UBC Library has
several copies of older editions which you can borrow.
Clickers: I'll be using the online iClicker Cloud. You don't need to buy anything, just use your own computer or mobile device, and set up a free UBC iClicker account, see: iClicker Cloud Student Guide
Labs: There are no labs in PHYS 108. All programs/specializations in Physics, Astronomy, Biophysics require you to have the PHYS 119 lab just to be eligible to apply for any of our specializations for 2nd year. A few other specializations in the Faculty of Science will also require you to take the PHYS 119 lab - if you are not sure, please consult the UBC Calendar or Science Second year specialization guide for specific requirements for the 2nd year BSc programs which interest you.
If you are not sure which program you plan to enter next year, you are strongly encouraged to take the PHYS 119 lab in order to keep many more options open for next year. All BSc degrees have a Laboratory Science Requirement, and PHYS 119 satisfies it.
If you took PHYS 107 here at UBC, you take PHYS 109 lab (it's a continuation of the PHYS 107 lab): You can look up lab sections from the PHYS 119 Course listing .
