TA: Reece Elling  (ReeceElling2022@u.northwestern.edu)

Structure: This online version is being used because of the COVID-19 pandemic. It’s an experiment, being built in real time. Not everything is ready, so things won’t be perfect and will evolve. We’ll all have to be flexible in this tough time. Still, we can have a good time and learn a lot.

Lectures (labeled as “including audio” once completed) are prerecorded, so you can download them and watch the power points at your own convenience and pace. You can also download a pdf to print. Contact us if you have difficulties.

We’ll have Zoom meetings at the scheduled time (1100 central) Tuesday and Thursdays for for discussion of class questions and homework due that day, aspects of the material, and homework help.

You may work (presumably remotely) with other students on the homework problems and class questions, as long as at the beginning of each assignment you list whom you worked with and on which parts. Please turn in problems and questions on Canvas. Computer problems can be done by writing programs or using Matlab, Excel or equivalent.

Despite the hassle, let’s bear in mind that this is a neat topic and is fun learning!
