Webcourses errors Thursday

There were bunches of hiccups in the Webcourses server Thursday afternoon that affected the exam performance for some of you. I am asking the site administrators how-what-when-why. I will let you know what I learn. Stay tuned.

Optics mini-quiz ready to roll

Students, there is now an optics mini-quiz for the Einstein Learning Module. It covers concepts and sketching from chapter 17.

In case you are wondering and worrying, our entire module is now just chapter 17, on account of my lecture sections could not catch up to you guys. They are not even to chapter 21!!! You all are way ahead.

So your exam on Thursday is going to be chapter 17 only, and a bit smaller than usual: probably

1. 12 multiple choice questions, 3 points each;
2. One or two brain-burner matching questions to generate another 14 points between them.
3. Total pointage = 50, as needed for the syllabus.

Go try that mini-quiz and be ready to think visually!
