One more ch. 21 podcast, concerning circuits.

YAY. Another chapter 21 podcast, for Exercise 18, p. 445, which is about circuits. You can also use the podcast to tackle exercise 17, 19 and 20, which are very similar to exercise 18.

Plus, the podcast ends with an open-ended brain-burner that we can talk about in Webcourses discussions.

New podcast plus two digital videos

The Uvision visual podcast site has a new podcast about batteries and currents, based on two conceptual questions from chapter 21.

Also, I have got the links re-established for two digital videos on static electric field behaviors.

1. Static cling shows the electric field, even field lines, for a toy balloon. This to the concept of induced attraction and field lines in chapter 20.
2. Electromagnetic interaction is a digital video of the polarization demonstration shown in Fig. 20-5.

New podcast about subterranean mammals

New podcast on our alternate podcasting site. It concerns exercises 9 and 10 on p. 225, which some of you have queried in discussions.

Maximum overlap waveforms spreadsheet file is now in Photons module

As promised, the spreadsheet mentioned in the visual podcast on superposition is now in Webcourses. The spreadsheet is called max_overlap.xls, and it has two access links.

You can change the snapshot time from t=5 sec to any other time, and the waveform will re-calculate and re-draw itself. Pretty slick. Try it out and see if it makes sense to you. Look in the "Photons, electromagnetic waves and energy" module.

Brand new podcast episode at Uvision; ex. 13

There is a brand new podcast episode for brain-burner exercise 13, p. 311. It is at out Uvision podcast site. It is a visual podcast, so it is best viewed in iTunes or an iPod. Your web browser might be OK. Always toggle to full screen.

The Uvision podcast site is linked in our Webcourses homepage. Look for the globe-on-page icon on the homepage. Enjoy.

Sketching podcast

Today's lecture on campus was highly appropriate to you Albert Einstein learning module. It is all about sketching in exercises 1, 2 and 3 of Ch. 17. I set up its visual podcast this afternoon. It has all the sketches from my lecture embedded in the visual track. You will find it on the lectures side of the Uvision website.

Also, I have set up links to the four large scan files, 700 x 540 pixels. Click on each image below to open out the large size file.

Michael Faraday Learning Module is ready to go.

I just set up our second main learning module, the Michael Faraday Learning Module, which covers topics from electromagnetism and molecules. You will find the icon in the upper left of the course content home page. There are two mini-quizzes ready today and, of course, the concept guides.

I have included a special new mini-concept guide on waves, covering a slice of chapter 15.

This learning module has the advantage that you can move around in it almost at random, instead of the strict sequence of the Sir Isaac Newton Learning Module. So you can study for a few days in chapter 20 on the electric field, then skip over to chapter 12 to look over the states of matter - solid, liquid and gas - and then back to chapter 20.

There will be some new visual podcasts, so keep an eye on the Uvision site.

Try to work through the mini-concept guide on waves before launching into chapter 22.

You are now GO for launch!

Podcast update

I just published some more exercise podcasts at Uvision. There are exercises up to and including chapter 6, even numbered exercises. I will be creating a few strategic podcasts for exercises in chapter 7 and 8.

There is also a lecture on projectile motion and gravitation on the lecture side of Uvision.

Podcasting of lectures and exercise helps

I have set up a visual podcasting site for my lecture classes that you online students might find helpful. It is called Uvision.

Uvision

Take a look at it, subscribe to the two visual podcasts (lectures and exercises) with iTunes, and see how you like it. There are basic instructions for new users on the welcome page.

A few parts of the lecture podcasts might not make sense to you, like mentions of CPS, but the main part: yes, it ought to help you learn. Give it a shot.
