Angular momentum rules in the NFL.

Think of the angular momentum vector for Jerome Simpson making this TD.



Excellent.

Chuck Norris bonus

I just finished uploading Chuck Norris bonus points:

1. Chuck Norris Day mega-review clicker session (2 points max)
2. Chuck Norris Mega-combo homework (2 points max)

However, I am still working on last minute changes and updates. More work to do before grades are due at noon!

Morning Sec. 0001 scores UP.

You all in the morning lecture section 0001, your scantron scores are up now. Also, your clicker scores are up, making your Final Exam score complete. Now you can get your final semester points total worked out.

Sec. 0002, I am still working on your clicker points.

ALSO: for all sections, I am still processing Chuck Norris data (iClicker and HW) plus several lectures worth of iClicker data. So it will be rolling into place in the next few days.

Point totals now in effect

Per the syllabus, the following point totals are now in effect for figuring out semester grades.

Letter grade	Points needed
A	216
B	180
C	144
D	120
F	<120

Note: nobody has final tally yet -- finals still being uploaded etc., iClicker data from last two weeks of lecture, etc. are still in flux. But this table shows what we are shooting for, and eventually your semester point total will be complete, falling into one of the above ranges.

ALSO: I do not round off anything other than the HW and clicker pointage. Do not confuse yourself by referring to percentages. Only points determine your semester grade.

Afternoon sec. 0002, your final scantron scores are up!

Scantron scores are now UP for the afternoon section 0002. Max possible was 79.

I am still working on the clicker points, so hold your fire on that for a little while longer.

You guys in the morning sec. 0001, it will be a while on your scantrons.

Bonus points subtotal

THere is a new row on your My Grades page in Webcourses, "Bonus points subtotal," which tallies up all the bonus point opportunities.

I will be working on bonus points for the next few days, so your subtotal in this row might change up or down, disappear, reappear then disappear again.

I have exam scores from Sec. 0002, the afternoon section. I will try to get them posted this morning or this afternoon. Keep an eye on your My Grades page.

Final Exam today
1:00 PM, sec. 0002

One spot open in Tanner's group

A spot has opened up in Tanner's SSG. Maybe one of you reading this will notice it and NAB that spot.

Chuck Norris HW

The Chuck Norris Homework assignment, a mega-combo review set, will activate at 5 PM.

Signups will start tomorrow afternoon for Saturday, Sunday and Monday SSG's.

You can click in there now and view the schedules for all but Matt's and Tanner's groups, then decide which to shoot for when signups open.

Chuck Norris Day

Be ready for Chuck Norris Day tomorrow:

1. Chuck Norris mega-review in lecture, using i>Clicker 2, and
2. Chuck Norris mega-combo review homework Friday afternoon.

Make sure that you are ready for action and do not give Chuck Norris any guff.

iClicker points

I have a bunch of catching up to do in i>Clicker 2 data. Keep an eye on that on your My Grades page over the next few days.

Icy finger of doom. Excellent.

Excellent video of ice forming, salt separating out. Sorry, I could not figure out how to embed the video, but it is pretty nice.

BBC Nature - 'Brinicle' ice finger of death filmed in Antarctic bbc.in/tEbfXa

Homework 25, Mount Vesuvius

Homework 25, concerning magma pressure underneath Mt. Vesuvius, is now ready!

Enjoy!

Who has #8004D753 for an iClicker serial number?

If your i>Clicker 2 has serial number

8004D753

then you had better re-register it in Webcourses. It is not registered and it will not correlate to your semester grade without registration. The i>Clicker 2 software cannot handle unregistered clickers.

Homework and iClicker pointage

The conversion of your iClicking and homework to pointage on your semester grade is getting down to the wire. I have just activate the iClicker pointage row of your My Grades page in Webcourses.

The iClicker pointage is tricky to compute correctly in Webcourses, because it is not a real spreadsheet. For this reason, I cannot totally guarantee that your iClicker pointage will not change as we click through the last lectures of the semester. But for now, it is looking OK.

You can add up best three midterms, HW and iClicker pointage, then divide by 160 for your percentage going into the final exam.

Fast fast fast

Amazing. Today the test scoring center is moving fast FAST FAST! I can hardly believe it is the same red stapler guys.

Anyway, the afternoon section's scantron data will be up in Webcourses directly. Good.

Exam 4 scores, best 3 midterms are UP.

Students in the morning section, you can now see what your best three midterm exams are, a few lines below the score for Exam 4.

Students in afternoon section, your "best three midterms" will not be kosher until we get your exam 4 grades back. They are still in the possession of the red stapler guys in test scoring. Maybe by tomorrow we will have them back.

Light

Which form of light seems most interesting in this video?

Earth | Time Lapse View from Space, Fly Over | NASA, ISS from Michael König on Vimeo.

Bonus point questions OPEN

I just opened up the bonus point opportunity in Discussions.

1. Construct a multiple choice question about a concept from the covered chapters and lectures.
2. Label the correct option with an * asterisk.
3. Below the question, skip a few lines and then type in the day of lecture, the homework assignment, or the page in the textbook that gave rise to your question -- this way other students can study up on this concept.
4. In the "Subject:" box, type in a short phrase that describes the concept in your question.
5. If your question is good enough to use on the exam, I will award you a bonus point, plus
   1. you will already know the right answer to it (one question on the exam guaranteed that you know the answer), and
   2. so will anyone who studies through this discussion area!

Take a look at my example question, be creative and make your question a good one.

Sorry for SSG delay

We had a football injury in my family today, trip to doctor for stitches etc.

So....

The SSG signups did not get activated at noon as I expected. However, I will get them opened at 7 PM, tomorrow night, 7 PM, and this time for sure!

Isotope in the news

Radioactive iodine, ¹³¹I, in the news.

Nuke agency reports unusual radiation in Europe Associated Press Vienna, Austria

The International Atomic Energy Agency says the "very low levels of iodine-131 have been measured in the atmosphere over the Czech Republic" and elsewhere on the continent.

Look at Webelements.com and see if you can tell why the last sentence in this article mentions a specific number of days.

Volcanic outgassing, Canary Islands

Carbon dioxide. Notice the dead fish -- maybe too much CO₂ dissolved in the water?

SSG signups will commence on Saturday at noon.

Signups for special study groups (SSG) will commence on Saturday at noon.

For now, you can look over the schedules of the groups and see which group fits your schedule. Then on Saturday at noon, I will set the group size to 7, and you'll be able to sign up.

Gloria's S.I. review prior to Exam 4

Give the S.I. review session a try, if you really want to crush Exam 4.

Exam 4 S.I. Review

Monday, Nov. 14

7:00 - 9:00 PM

MAP260, Math and Physics Bldg.

Note:

1. Gloria's review sheet and study guide will be posted by Sunday evening.
2. To find out when the final exam review is, come to S.I.!!

Homework 23

You can begin homework assignment #23 now. It will go over several of the concepts in chapter 17 related to lecture. Make sure you have done the reading before you burn through all of your attempts.

Image: lunar meteorite NWA 032

Podcast

There seems to be a gap in the podcast for morning lecture, mainly during the iClicker questions. So just wait it out and my voice will come back in when the notes return.

ALSO: You could listen in on the afternoon lecture.

Special office hours for Rylee

Rylee will be having a set of special office hours next week on Tuesday afternoon from 3-5 at the Starbucks in the Bookstore! This is on account of classes being cancelled today for football.

Homework 21

We are on a roll, more lovely homework! Homework 21 is due on Friday at the beginning of your lecture, as usual.

Image: Allende meteorite

Homework, so handy and yet so lovely

More homework will activate at 3 PM today: Homework 20, concerning bonds between atoms etc.

It is due on Wednesday, at the beginning of your lecture, as usual.

Homework 19

You can now view the mini-study guide for homework 19 over the weekend. Look in Nitro's homework folder on the Webcourses homepage.

Exam 3 scores are all UP.

Exam 3 clicker and scantron scares are now UP, for both sections.

Lecture today is ON.

Morning section, you have homework, even though we got locked out.

Afternoon section, we will have lecture as usual, and this time let the early birds from Sec. 0001 catch up with you instead of the other way around.

Image: Action photo of student from PSC1121 morning section today.

Exam 3 is in the pipeline.

I have started looking at the clicker data for both sections and the scantrons are cooking. More on Friday, hopefully sooner.

Oh, boy!

What a test you will have tomorrow! All I can say is: make sure your cranium muscle is ready!

Bonus point opportunity

The special discussion area is now open for earning bonus points with a GOOD question of your own creation.

GO! GO! GO!

NOW the two groups are ready

NOW you can get into the two new SSG's. Look for the blue and white icon in the Webcourses home page.

Sorry for the delay.

Noon or so, two more SSG's to sign up for

About noon today, we expect to have two additional SSG's running, for which you can sign up.

So be ready at noon or so. We will announce it here, then open it for signups.

HW 18 is ready!

You can now tackle quantum physics concepts in Homework 18. It has a YouTube that you should view:

GO for SSG signups, noon today!

1. SSG signups activate at noon today for the first group, as discussed in lecture on Friday. Click into the SSG folder on the course home page, and you will see this blue and white SSG icon in the SSG folder when you are cleared for signups.
2. You all in the second group, you will be activated for signups at 6 PM, Sunday evening.... if there are any spaces left!

SSG signups, Saturday midday

I expect to activate SSG signups for the first group of students about midday on Saturday. Be ready to move fast around noon or so and make sure you snag a spot in a good SSG.

Homework 17 is running now.

You can now get to work on HW 17. It is due as usual, on Friday, at the start of your lecture.

Weirdness in HW 15

I corrected a typo in Homework 15 this morning, changing "proton" to →→ "proton 1" and it goofed up the scoring for some reason.

To correct for it, the do-over in tonight's HW 16 is for 8 points, double what it was for HW 15. If I can't get it squared away on HW 15, then do not fret about it. I will adjust the points total at the end of the semester, and even if I were not to do so, 4 points out of a few hundred is not going to change anyone's HW pointage by much if anything.

GO

Homework 16 is ready.



All brain-burners! But are you ready for it? Will you get Rick Roll'd or will it be Gino Time for you?

Homework 15 ready

Homework 15 is ready to launch, which it will do at 3 PM today. There are two brain burners that will challenge everyone!

Due on Monday.

Typo in morning section's exam 2

I just re-graded exam 2 after finding a typo in one of the true/false questions. For those of you who noticed it, bravo! The "..Exam 2 scantron" score is now up to date. Most of the class gained one more point.

Uh oh

Confound it! My plan has failed. I have to cancel tonight's homework. Not enough time.

But everyone can read section 6.1 to prepare for lecture on Friday and the gigantic HW you will definitely have this weekend.

Heads up: Homework about supper time

HW tonight is going to be a bit later than I told you this morning. Look for it maybe about supper time.

Logs

If you want to start estimating your semester grade -- as if I were to award it now -- you can refer to these two new files in Webcourses:

1. Homework log, which gives you a rundown of the homework points we have had so far this semester. These homework points will be converted to 20 points on your semester grade, as discussed in the syllabus. The homework log is linked to the homework folder, at the top of the page.
2. i>Clicker 2 log, which does the same thing for how many clicker questions we have asked in class so far. The number of i>Clicker 2 questions you answer will also be converted to another 20 points on your semester grade, as discussed in the syllabus. Look for this log file linked to the course home page, with the little i>Clicker 2 icon.

The HW subtotal and i>Clicker 2 subtotals you have earned are also on your My Grades page in Webcourses. With your subtotals and the log files, you can get an estimate of your clicker and HW pointage.

In addition to the HW and clicker pointage, you have exam pointage that goes straight into the semester grade without conversion.

Homework 14 is UP.

You can start working on Homework 14 at 3:45 PM. It is due, as usual, at the beginning of your lecture on Wednesday.

It behooves you to read the remainder of chapter 5 before tackling this HW.

Doppler shift, freight trains

There are tons of rail fans uploading to YouTube, and many of their videos let you listen to a nice Doppler shift. Here is one we listened to in lecture today -- one among zillions that you could listen to.



Listen to the trains blow their horn, in the first 45 sec. or so, then a bell ringing at 5:20 and and an excellent horn at 7:15.

Standing waves from spring semester

Take a look at the standing wave demonstration from last spring, Gloria and Lee operating the Slinky.
You can read more about standing waves and harmonics on pp. 129-130 of our present textbook.

Here is another YouTube, with Amanda and Rylee. They actually get up to the 2nd excited state. Nice.

Sound fights

Unfortunately, the morning lecture is chopped into three parts, the middle part being slides but no audio. I am not sure what happened, but I will make sure the afternoon podcast is a good replacements.

Exam 2 scores are UP.

I just uploaded the scantron scores for everybody. You can now look at the clicker score, the scantron score and the total Exam 2 score.

Go have a look.

Clicker question #38 is UP.

I just posted the iClicker question points for Exam 2. It was a "heat-melt-heat" calculation.

Also, there is a new row with the actual answer you sent, plus an indication of whether it was correct or incorrect. About half of each section got it correct.

P.S. three students with unregistered iClickers did not get points.

Exam over!

WHEWWWW!

Exam 2 is over. Exams are in at the test scoring center, so we will wait for a while.

So for now, rest your brains and get some ZZZ. And I will see you all for Friday regular lecture, where we will continue talking about waves and oscillations. AND more homework for the weekend.

Exam 2 today

Midterm Exam 2 today

Expect the unexpected

Notes on heat

These two goombahs were supposed to be studying for midterm exams, but instead, they got in trouble with Chuck Norris.



Study for Exam 2, and check out the set of study notes on heat. It is linked to the homework page.

Homework 11 extends.

I am extending HW 11 to Wednesday morning, and I am setting it for one more attempt, 5 attempts available, so that everyone can get at least one more shot at the heat concepts.

This will allow you all to tie together my final remarks on heat from Monday lecture.

Homework 10 is ready.

You are GO for launch with HW 10. Have it squared away before your lecture on Friday.

L15 calculation

I just uploaded your clicker data from Monday. Also:

1. I made the calculation a two-pointer, so that I could award partial credit for a few people who rounded off incorrectly.
2. As a study help, I inserted your actual answer, as you typed it in, in the row marked "Your answer to L15 calculation" on your My Grades page.

Afternoon podcast substitute

Substitute procedure for afternoon podcast:

Listen to the first 9:30 of the afternoon podcast	→ → →	switch over to the morning podcast, which follows the same basic outline.
Also: view the two doc cam PDFs, from morning and afternoon lectures. They cover the same basic ground, but slightly different numbers for the wheel example and the clicker question.

Monday afternoon podcast troubles.

I understand that the audio goes OUT on the Monday afternoon podcast, at about the 9:35 mark.

Alternate: download the morning podcast and the PDF of the morning doc cam. That was a slightly different lecture, but the same basic outline.

Homework, homework, number nine

Your homework assignment for tomorrow, HW 9, is now ready in Webcourses. Look for the video about Daryl Dawkins, a.k.a., Chocolate Thunder.

No homework, again!

In a shocking development, I have decided once again to assign no homework this weekend.

Try not to scream in agonizing mental pain without any HW for the weekend!

Exam 1 roundup

Your Exam 1 scores are up. Look at your My Grades page in Webcourses.

However, the scores for a few students are not posted yet -- special situation like your PID or exam form out of order. We will be putting those in by hand, probably tomorrow.

Homework 8 is ready.

By popular demand, homework is back in action. HW 8 is now up on Webcourses, and it will go active at 3 PM today.

Go for it!!!

Exam blurb sheets are UP.

If you look for the dancing banana on Webcourses, you can click in and get the blurb sheet for your exam form. Along with the printout we have handed back the past two lectures, the blurb sheets make a nifty study tool.

No homework tonight

I decided not to give any homework tonight.

But Wednesday, look out! We will have a ton of HW.

Office hours for Dr. B

Here are the office hours I will hold for the rest of the semester, up until the last week of the semester:

Monday	Tuesday	Wednesday	Thursday	Friday

In late Novermber, I will announce some additional office hours for final exam week.

Brain burners ahead

The exam is ready for tomorrow, including some nifty brain burners.

Excellent.

You will not be getting any cliclker points until these are registered through Webcourses and only through Webcourses.

Exam 1 coverage

I was not able to get as much into Friday's lecture as I wanted, so we will keep Exam 1 to the following two areas:

1. the parts of Chapter 24 covered in the first few lectures, and
2. Chapter 2.

I will start Ch. 3 on energy on Friday.

Study lecture notes/podcasts. Homework and i>Clicker questions make a good mini-study guide. Don't forget the doc cam PDFs from Sept. 2, Double check the readings I mention in lecture, and then expand your reading from there.

Homework 7 about jumbo egg

Your jumbo egg homework assignment is ready now in Webcourses. It is Homework 7, due Monday before YOUR lecture section meets.

Your clicker is unregistered if it is on this list.

Here is a set of serial numbers of clickers that are attempting to click in lecture but which have no name attached.

#814561A5
#81A488AD
#81BDCFF3

Homework 5 is ready.

Callahan was not ready.

Are you ready? Homework 5 is ready for your studying pleasure. Due on Wednesday, Sept. 7th.

iTunes and doc cam, sec. 0002

I just finished up the podcast of today's afternoon lecture, plus the doc cam PDFs. GO! GO! GO!

Doc cam files

When I use the doc cam in lecture, you can take notes and sketch with me. Later I will scan my work and post it in PDF on Webcourses. Look in the folder with this icon.

Morning section 0001, your doc cam file is up. Afternoon section 0002, be ready to sketch and diagram.

L5 data are up for afternoon section 0002.

Students in afternoon section 0002 may now view today's clicker data in their My Grades page on Webcourses.

L5 clicker scores are up, for morning section.

I just uploaded the iClicker scores for today, for section 0001. Look toward the bottom of the page, where you'll see the "L5 answered" and "L5 correct" rows.

Every time we use clickers, I will upload the data in this manner.

You guys in Sec. 0002, you'll have to wait til after lecture, maybe tonight, to see your clicker data. So hold your horses, but be ready for clicking in class at 1:30 PM!

S.I. schedule

Gloria Scott just gave me the Supplemental Instruction schedule. Here it is:

Day Time Location Monday 10:30 - 11:20 AM HPA 110 Tuesday 12:00 - 12:50 PM MAP 407 Tuesday 4:30 - 5:20 PM CL1 212 Wednesday 5:30 - 6:20 PM CL1 212

As always, S.I. is optional: make it if you possibly can. It will help with your semester grade.

Shorebird migrates through Hurricane Irene – USATODAY.com

Interesting article about distance scales relative to Orlando. We study climate objects like North Icelandic Jet and Hurricane Irene that operate on scales that reach from West Africa to Iceland. This bird actually flies on the same distance scales. Amazing.

Grade book

The grade book seems to be having conniptions today, like last week. So your early clicker bonus point will have to wait until tomorrow (Tuesday) before it shows up on your My Grades page.

This morning's experiment

Here is a quick YouTube of our experiment with Asa this morning: what is his motion on the skateboard, in terms of distance, time and speed?

Friday lecture, oooops!

For some reason, we lost the recording of the Friday morning podcast. But no worry. I always record the afternoon lecture, too, and it is now up in iTunes U.

So everybody, both sections, listen to the Aug. 22 afternoon lecture in iTunes U.
