HW 16 is going.

You can now try out a brain burner deluxe in Homework 16, due on Monday.

Homework 15 UP.

Homework 15 is now available. However, since it is late, I will make it due on Monday, 10:30 AM.

Office hour this morning

We will have office hour this morning, 10 to 11 AM, room PS158 in the first floor of the Physical Sciences building (PS), right by the main entry.

Homework 14 is running.

Your next homework assignment, #14, is now running. It is due on Wednesday, 10:30 AM.

Your clicker points are UP.

There were plenty of students who got the clicker calculation correct yesterday, for 3 points. The answer was 1815 calories to prepare that nice cup of tea.

Also, after eyeballing every answer, I decided to award 1 or 2 partial credit points, depending on what you sent in for an answer.

All of this is now posted in Webcourses, on your My Grades page, including whether you got partial credit or not.

Bonus points question opportunity

For those of you that would like to try to earn another bonus point, the discussion area for that is now open in Webcourses. If your questions is good enough to include on Exam 3, then you will earn a bonus point.

Dr. B highway disasterness, but Exam 3 on schedule for Wed.

Sorry that I had to cancel lecture today. My vehicle had a slight disaster on the highway on the way to campus.

We will have Exam 3 on Wednesday according to the normal schedule.

Look in Webcourses for a review sheet -- we were going to do it in lecture today using iClicker, but you can use it on your own as a study sheet.

Trouble in HW 13

I have been having trouble getting Webcourses to activate your homework. I should get it squared away soon. Hold your hat and be ready for some HW about waves.
