revision

I revised the assignment slightly, so that you can use both sides of the paper, this assignment only. The new PDF has replaced the one from last night.

By the way, both PDFs include the answer for the scattering angles in the problem we started in lecture. SO.... if you can finish that problem we started, getting the right scattering angles, you can then apply the same method to the actual homework to hand in.

Scattering

Your written homework #7 is a scattering problem similar to the one we tackled in lecture today. The PDF is now available in WebCourses2.

Deluxe scattering machine in Geneva, Switzerland.

Last week's podcasts

I have embedded the doc cam work from Wednesday and Friday into the lecture podcasts, which are uploading now. Lots to learn.

This and that

I am working on some odds and ends in Webcourses2, including updating the iClicker 2 data. Friday's lecture data is now up, and that makes the semester's question count 44, as of Friday's lecture.

I also created a new line on your Grades page, showing the estimate of your class participation points on the semester grade, out of 48 possible, as if I were to compute semester grades today. If you have more than 37 answers (i.e., more than 85%), then your pointage is 48/48. Otherwise it is scaled following the method on our syllabus.

Note: This is a preliminary estimate. Your iClicker 2 participation pointage can definitely change, because there are a lot more iClicker 2 questions between now and the end of April.

Get going on Monday's WebAssign homework.

There is a smorgasbord of two-dimensional collision problems in your WebAssign homework for Monday. Your are GO for launch.

Homework 6 is ready.

Your written homework #6 in PDF is now ready for download. GO! GO! GO!

Normal operations resume at noon.

Just got the all clear from UCF:

UCF Main campus will resume normal operations at noon. Tower 1 remains evacuated.

I will see you at lecture, 3:30 PM.

Main campus closed until noon, Monday.

Emergency alert:

University of Central Florida’s main campus is closed for classes and employees until noon. Essential personnel should report to work.

Any class scheduled to begin before noon today, is cancelled.

I hope we will be cleared for our lecture meeting at 3:30 PM. Be prepared to attend.

updates

Next WebAssign homework is ready.

Your WebAssign homework is ready to activate at 10:00 AM this morning.

Study in chapter 9 as far as the center of mass concept, p. 254.

The first two exercises are about center of mass. Problem 6 is one we worked on in lecture, Friday afternoon. The last exercise in this assignment is one of the brain burners that you have to work on sequentially and finish -- or get no points.

Remember to use your eyes and diagram carefully.

We will take Friday off today.

We are quite a bit ahead of where my class was last semester at midterm. Good.

That being the case, we can take this Friday off from lecture, and I will see you on Monday, after spring break.

Keep your eye on Webcourses2, however, because I will be grading the exam and posting scores in the next few days.

So keep your pocket protectors squared away, and enjoy your spring break!
