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.

GO for learning module

Your learning module for this week, concerning angular momentum, is now available. It covers chapter 8, and I have attached a mini-blurb on chapter 15, too, which we can start looking at now.

Webcal to which you can subscribe

I set up a simple calendar for the class, and I published it to me.com, the Apple site. There is a link to it on our home page now, too, and you can subscribe to it if you have a calendar app. I will be adding blurbs to it as we go through the semester, but for now the data extends up to the week of Exam 2. Eventually, I will load up blurbs extending to Exam 3 and then extending to the final exam.

Let me know how you like it.
