Exam 1 results

I will release Exam 1 results first thing tomorrow morning. For now, I think you can see you score.

Good night, gotta catch up on ZZZZ.

Exam 1 is ready to go.

Your Exam 1 is now published and ready to go for 10:05 AM. You will have 60 minutes to complete it, so block out a solid one hour from your schedule that

1. starts sometime after 10:05 AM and
2. ends before 11:59 PM.

GO! GO! GO!

Δt and what it means

Have you been wondering, what's the use of this Δt interaction time that Dr. B keeps gassing about?

How about looking at it like a car driver?

1. Is it better to stop short, like this driver...
   
   
2. or to stop long like this guy?
   
   

That can be a life and death proposition. You definitely like long stopping time when driving.

Next learning module is ready.

Your learning module C is now ready. The mini-quiz will open at supper time tonight.

This is the last module that we will cover on Examination 1, although I will activate learning module D next week.

Learning module B is up.

Your learning module for this week is now functioning.

Remember to keep your mental composure at an even keel as we fight back against the machines, including the new Terminator known as Webcourses2. :D

New podcast

There is a new podcast in our iTunes U area. It is over the Chapter 2 topics of gravitational weight force and "g" which are in pp. 43-44.

Please forgive my weak voice on this podcast and the lisp and inability to pronounce the letter G! I just had surgery in my mouth, all kinds of stitches plus pain, so talking is semi-discombobulated right now. I hope it will be better in a few days, especially this maddening lisp!

Look for the new podcast with the Boeing 747 carrying the space shuttle. Click the little square icon that is inside the progress bar on the left, and then all the diagrams, equations, formulas and notes will pop out into full screen.
