L6 data is UP.

Both sections of L6 clicking data are up, AM and PM.

Have a great weekend with the William Hung Fanboy Convention, or wherever it is you are headed. :D

See you next Wednesday!

Next homework is UP.

The next homework assignment is now UP in Webcourses. HW 2 will activate at 3 PM today, and it will be due on Wednesday next week at the beginning of your lecture.

PDF of Monday lecture

I just set up a page for PDFs of lecture slides for last Friday and this Monday, which were not in the podcast. Look for "Lecture PDFs, emergency mode" in the right hand side bar of Webcourses.

I just placed the Monday PDFs. The PDFs from Friday, I will work on directly.

L5 PM is up.

The clicking data from yesterday afternoon is up, L5 PM.

HW 1 is ready.

Make sure to have skimmed Ch. 2, if possible, before tackling HW 1, our first homework assignment of the semester.

Data from morning participation is UP.

There are several new rows in your Grades page in Webcourses. Each row starts with the 12th letter, L, for "lecture", then a number to indicate which lecture.

Today's data is L5.

Additionally, the data indicate

1. how many questions you answered and
2. how many of the ones you answered were actually correct.

Afternoon section, you will always have zero for anything that reads "L5 AM..." But your data this afternoon already has a slot ready for it, and I will upload that sometime after lecture.

Ignore the Grades page's percentages.

The percentages at the bottom of your Grades page are useless and misleading, but I cannot turn them off. Unfortunately, for some of Canvas' features, it is Canvas' way or the highway.

That being the case, it is good for you to simply ignore that stuff in gray at the bottom of your Grades page, e.g.,

Water in motion

Interesting video of a sink hole breaking out. Check the change in the waterline at the end of the video.

Bonus point up; iTunes U

I posted the bonus point from today's lectures IF your iClicker2 was registered via Webcourses. YAY.

For the rest of youse, NO MORE SNOOZING! Get those rigs registered up, in Webcourses, asap, and then you will get a bonus point on Friday, if you come to lecture.

ALSO: the afternoon podcast is UP in our iTunes U area.

Session data, morning section

I just uploaded raw scores from this morning's i>Clicker2 session. It will show up in your Grades page, if

1. you clicked properly, and
2. your i>Clicker2 is registered in Webcourses, as of about 10 AM.

Section 0002, at 1:30 PM, you'll have your shot. Be ready.

Morning lecture podcast is UP.

You can now download and view the 8:30 AM Wednesday morning lecture, in our iTunes U area. Look in Webcourses for the "iTunes U" page, right hand sidebar.

You can get an eBook, now.

You can now purchase the eBook version of the Tillery Physical Science textbook. Look for the "eBook etc." page, in the right hand side bar of Webcourses, then follow the instructions. You can use a credit or debit card.

Bonus points: Early iClicker registration

These students have already registered their i>Clicker2s.

1. Erica C.
2. Natalya C-Z
3. Robert D.
4. Cory G.
5. Ja'Far K.
6. Daniel K.
7. Kari-Ann L.
8. Zachary M.
9. Baily S.
10. Andrew S.
11. Casey S.

Excellent!

Tomorrow, Friday and Monday we will have some simple practice sessions on i>Clicker2 in lecture. For students who have registered in Webcourses, like the students listed above, they will get one bonus point on their semester grade for each lecture they have been registered before Wedneday next week. That is potentially 3 bonus points, more than 1% on semester grade.

Nice.

eBook soon

The McGraw Hill eBook site is still processing our request for the textbook. They've been slow and 503 a lot, being as how it was the first day of school yesterday for so many places, tons of students.

I am hoping it will be squared away and available to you all sometime today.

Webcourses is my friend.

NOT.

But even if Webcourses/Canvas is not our friend, we will persevere and use all of our skills to defeat it this semester.

No homework tonight, but do try to get the textbook and your i>clicker2.

Welcome aboard, everybody!

Cold ocean water, from size of your hand to size of Pacific Ocean

Incredible finding!

The cold surface sea water that keeps the Galapagos dry is part of a basin-scale structure called the equatorial cold tongue, and is known to originate from beneath the surface.

...the equatorial cold tongue [figure above] is a tale of remarkable interactions across eight orders of magnitude, from turbulence (10^-1 m) to the size of the vast Pacific Ocean (10⁷ m).

Climate science: Unequal equinoxes
by Shang-Ping Xie

This is amazing once you consider the size scales involved. The extent of the equatorial cold tongue reaches from about the Galapagos Islands west to about Jarvis Island, an arc of about 69°. If you factor in the average depth of the Pacific ocean, about 2000 meters, it looks about like this scale diagram:

OH, brother! What a textbook, from the master!
