Hey, Look at this! You can link up with your colleagues and have some phun talking about what ever you want to with the UIUC Society for Physics Students. Here's a link to see what's going on there:

New Homework assignments will be published on this page on Wednesdays and discussed briefly in the next class meeting (Friday). They will be due on Fridays of the next week at 1159 pm. Just to be clear, that is 9 days after the homework is assigned. You can submit your homework up to two days later (Sunday evening at 1159pm) for 90% credit. After that late deadline, no credit can be earned. On Tuesdays at 5 pm we will have an office hour to discuss the assignment due on Friday of that week. Between the discussion in class on Fridays and the HW office hour on Tuesdays, you should be able to avoid spinning your wheels unproductively.

To hand in HW assignments, we use Gradescope. If you do your HW on paper, carefully scan your solution pages to produce a clean and legible pdf file. If you use an electronic tablet for your work, use it to produce a pdf file. Submitt your file to the Gradescope HW depository. It is important that your file can actually be read and graded. Illegible files will not be graded and will result in zero credit.

Starting on Monday Jan 23, 2023, we will use iClickers to poll the class on questions on topics we have are covering in class. As of right now, we will not grade the responses, but participation in this activity will feed into the classroom participation grade. You need to register your iClicker for this class using your Gradebook page.
