You can earn a bonus point by contributing a question for Exam 2. If it is good enough for me to use on the exam, you will earn one bonus point. Nice.

Mini-quiz for chapter 15, waves
Chapter 15 on waves is a mini-chapter. There is a mini-quiz associated with it, in the Week 7 learning module. I just activated this mini-quiz. It's very basic -- taking you over the basics of waves and oscillations: wavelength, amplitude, frequency, speed etc.

Ten degrees
It is interesting to view the tilt angle of the space shuttle main engines.
In this NASA video, you can see about ten degrees of tilt away from the central axis. Think of why this must be done when the solid rocket boosters are still strapped on. Lots of physics concepts show up in this one video.

Last module for Exam 2 prep.
Your last learning module preparing for exam 2 is now up. The focus now skips to chapter 11.
Apologies
I apologize that the the rows in your My Grades page are all scrambled. I have tried everything to square them away, to no avail!
Every semester it becomes discombobulated, but for some reason, this semester is the worst ever.
